Atlantic Hurricane Outlook – October 16, 2025

On October 16, Tropical Storm Lorenzo continues to weaken while tracking northeast over the central Atlantic with winds around 40 mph. Increasing wind shear, cooler waters, and dry air are causing the system to lose strength. No other tropical development is expected across the basin, and Florida and the Gulf of America remain quiet aside from minor marine swells and rip current risks.

Tropical Storm Lorenzo continues weakening over open waters; no new systems developing

Atlantic Basin Overview

  • Tropical Storm Lorenzo
    Lorenzo is weakening while maintaining a general north to northeast track over the central Atlantic. Lorenzo has maximum sustained winds of about 40 mph, with tropical-storm-force winds extending outward roughly 60 miles from the center.
    Lorenzo will shift toward the northeast later in the week and gradually dissipate, with no landfall expected.

  • Other Tropical Activity
    There are currently no other active tropical cyclones in the Atlantic, Caribbean, or Gulf basins. The NHC’s 7-day outlook indicates no additional tropical cyclone formation expected in that timeframe.

Environmental Conditions

  • Sea Surface Temperatures (SSTs):
    Lorenzo is traversing moderately warm waters supportive of tropical structure, though as it moves northward it will encounter cooler SSTs that accelerate decay.

  • Wind Shear:
    The system continues to face moderate to strong vertical wind shear, which is limiting deep convection and contributing to its weakening trend.

  • Dry Air / SAL (Saharan Air Layer):
    Surrounding dry air and intrusions of dust remain factors, suppressing convection in outer bands and preventing reintensification.

On October 14, Tropical Storm Lorenzo remains active in the central Atlantic, moving northwest with sustained winds of 60 mph. The storm is expected to turn north and then northeast, staying over open water as it contends with moderate wind shear and dry air. No other tropical systems are active, and the Gulf of America and Florida remain calm aside from routine marine swells.

Tropical Storm Lorenzo active over open waters; no land threats identified

Atlantic Basin Overview

  • Tropical Storm Lorenzo
    As of the 5:00 AM AST advisory, Lorenzo is centered near 17.3° N, 44.1° W, roughly 1,330 miles west of the Cabo Verde Islands.
    Lorenzo is moving northwest at about 15 mph (13 kt).
    Maximum sustained winds are near 60 mph (50 kt), with tropical-storm-force winds extending outward up to 175 miles (280 km) from the center.
    The minimum central pressure is about 1000 mb.
    The forecast track calls for Lorenzo to continue northwestward today, followed by a turn north tonight, then northeast by Wednesday–Thursday.
    Little change in strength is expected over the next several days.

  • Other Systems / Disturbances
    No other tropical cyclones are active in the Atlantic or Caribbean at present.
    The 7-day outlook shows no additional tropical cyclone development expected in that period.

Environmental Conditions

  • Sea Surface Temperatures (SSTs):
    SSTs along Lorenzo’s projected track remain sufficiently warm to support continued tropical storm strength.

  • Wind Shear:
    Lorenzo is contending with moderate wind shear, which is contributing to a somewhat disorganized structure.

  • Dry Air / Saharan Air Layer (SAL):
    Dry air and Saharan dust are present in surrounding areas, which may suppress convective expansion, especially in outer bands.

Gulf of America & Caribbean

These regions remain quiet, with no organized tropical systems. The typical October pattern of scattered showers and thunderstorms continues.

Florida & Eastern U.S. Forecast

No tropical threat to Florida or the U.S. East Coast is foreseen. Lorenzo is expected to remain over open ocean, turning away from land.
Marine concerns—swells, surf, and rip currents—may extend across portions of the Atlantic as Lorenzo propagates energy westward, but no direct impacts are anticipated for coastal U.S. areas.

TL;DR – October 14 Snapshot

  • Lorenzo is active in the central Atlantic with 60 mph winds.

  • Steering pattern to turn it north, then northeast; no land threat.

  • Environmental conditions limit strong intensification.

  • Gulf and Caribbean quiet.

  • Florida & U.S. East Coast: no tropical impacts expected.

Atlantic Hurricane Outlook – October 13, 2025

On October 13, Tropical Storm Lorenzo formed in the central Atlantic with maximum winds near 45 mph and favorable conditions for further development. The system is expected to strengthen steadily as it moves west-northwest over warm 29–30°C waters. Meanwhile, post-tropical Jerry continues east of Bermuda, and Florida remains clear of tropical threats aside from elevated surf along the Atlantic coast.

Tropical Storm Lorenzo forms in the central Atlantic; Jerry now post-tropical east of Bermuda

Atlantic Basin Overview

  • Tropical Storm Lorenzo (formerly Invest 97L)
    The National Hurricane Center has officially designated Tropical Storm Lorenzo (AL17) in the central tropical Atlantic, located near 12°N, 38°W, or roughly 900 miles southwest of the Cabo Verde Islands.
    Lorenzo is moving west-northwest at around 15 mph, with maximum sustained winds near 45 mph and minimum central pressure near 1005 mb.

    Organization has improved significantly over the past 24 hours, with persistent convection consolidating around a developing center. The storm’s cloud structure shows banding features and outflow beginning to improve on its western flank.

    Forecast & Track:
    Lorenzo is expected to continue moving west-northwest for the next several days, gradually turning more northwest by midweek under the influence of a mid-level ridge.
    Environmental conditions—warm sea surface temperatures (29–30°C), ample mid-level moisture, and low vertical wind shear (10–15 kt)—favor steady strengthening, and Lorenzo could become a hurricane by Wednesday or Thursday if current trends continue.

    Model guidance (ECMWF, GFS, and HWRF ensembles) indicates Lorenzo will likely remain over open waters through the week, though some long-range uncertainty remains regarding a possible westward bend late in the period.

  • Post-Tropical Jerry (east of Bermuda)
    The remnants of Tropical Storm Jerry are now an elongated trough east-southeast of Bermuda. Gale-force winds (35–40 kt) persist along the northern edge, but the system lacks tropical characteristics and is not expected to redevelop. Seas near the trough remain 10–14 feet, gradually subsiding through Tuesday.

  • Subtropical Storm Karen (north Atlantic)
    Karen continues to weaken over the far North Atlantic, with maximum winds near 40 mph. The system is expected to lose its subtropical structure and dissipate within 24 hours over cold waters.

Environmental Conditions

  • Sea Surface Temperatures (SSTs):
    SSTs across Lorenzo’s path remain well above average (29–30°C) — highly favorable for sustained deep convection and intensification.

  • Wind Shear:
    Current shear is low to moderate (10–15 kt) in the central Atlantic, allowing Lorenzo to organize further. Slight increases in shear may occur later this week as the storm tracks northwest.

  • Humidity & Dry Air / SAL:
    The Saharan Air Layer remains present north and east of Lorenzo but has receded sufficiently to the northeast. Moisture surrounding the storm’s core is increasing, limiting dry air intrusion and supporting vertical growth.

Gulf of America & Caribbean

The Gulf of America and Caribbean remain quiet. No tropical development is expected in these regions through at least the next 5–7 days. Afternoon convection and sea-breeze thunderstorms continue as typical for October.

Florida & Eastern U.S. Forecast

There are no immediate tropical threats to Florida or the U.S. East Coast. Lorenzo is far out in the central Atlantic, and current steering patterns favor a northwest track away from land.

Residual swell energy from past systems, combined with seasonal transitions, will continue to produce high surf and rip current risks along the Southeast and Mid-Atlantic beaches.

Otherwise, Florida remains under typical early-fall conditions—warm, humid afternoons with isolated sea-breeze storms.

TL;DR – October 13 Snapshot

  • Tropical Storm Lorenzo (AL17) has officially formed in the central Atlantic, moving WNW with 45 mph winds.

  • Favorable conditions (warm SSTs, low shear, and increasing moisture) support strengthening—could reach hurricane strength midweek.

  • Post-tropical Jerry continues east of Bermuda with lingering gales.

  • Karen dissipating in the North Atlantic.

  • No tropical threats to Florida or the U.S. mainland at this time.

  • Marine impacts (swells, rip currents) remain the primary concern along Atlantic beaches.

Atlantic Hurricane Outlook – October 10, 2025

On October 10, Tropical Storm Jerry is weakening as it turns northward in the Atlantic, while a developing Nor’easter off the U.S. East Coast brings flooding rains, high surf, and coastal winds to the Mid-Atlantic and New England. Subtropical Storm Karen continues to fade over the northern Atlantic, and no new tropical systems are expected. Florida and the Gulf of America remain calm aside from elevated surf.

Tropical Storm Jerry weakens; Subtropical Storm Karen fading; Nor’easter developing off the U.S. East Coast

Atlantic Basin Overview

  • Tropical Storm Jerry
    Jerry is located about 80 miles north-northeast of the Northern Leeward Islands, moving northwest at ~17 mph, with maximum sustained winds of 50 mph. Tropical-storm-force winds extend outward nearly 185 miles to the east of center.
    Jerry continues to battle moderate to strong wind shear and dry mid-level air, keeping its convection displaced from the low-level center. Gradual weakening is expected as it curves north, and Jerry could lose tropical characteristics by Saturday, becoming post-tropical as it interacts with an upper trough.

  • Subtropical Storm Karen
    Karen, in the far North Atlantic, is weakening over cooler waters and increasing shear. It will transition to a post-tropical low within 24 hours and pose no threat to land.

  • Non-Tropical Coastal Storm / Nor’easter (Western Atlantic)
    A strengthening non-tropical low has formed just off the Mid-Atlantic and Northeast U.S. coastline, drawing deep Atlantic moisture into the region.
    This hybrid system—not yet tropical but highly impactful—is producing:
    • Heavy rain and coastal flooding from New Jersey through New England
    Gale- to storm-force winds along the coast and offshore waters
    Dangerous surf, rip currents, and beach erosion extending through the weekend
    The system will likely intensify further as it moves north-northeast, behaving more like a Nor’easter than a tropical cyclone. While not classified as tropical, its impacts on populated areas are as significant as a weak hurricane, and it should be treated with equal caution by coastal interests.

Environmental Conditions

  • Sea Surface Temperatures (SSTs):
    Warm (28–29 °C) near Jerry’s current location, but cooling rapidly northward. The Nor’easter’s energy source is baroclinic (temperature-gradient driven) rather than tropical heat.

  • Wind Shear:
    Strong upper-level winds dominate the western Atlantic—one reason Jerry is weakening and why the Nor’easter is deepening outside the tropics.

  • Humidity & Dry Air / SAL:
    Dry Saharan air continues to limit convection around Jerry’s western flank; mid-latitude dry slots are also influencing the Nor’easter’s structure.

Gulf of America & Caribbean

The Gulf of America and Caribbean remain calm, with no organized tropical activity. Conditions are dominated by localized thunderstorms and standard early-October convection.

Florida & Eastern U.S. Forecast

  • Florida: No tropical threats. Expect humid, stormy afternoons and increased rip current risk from Atlantic swells.

  • Eastern Seaboard (Mid-Atlantic to New England): Impacts are already underway from the non-tropical coastal storm / Nor’easter—including gusty winds, heavy rain, and flooding tides. Residents should monitor local advisories and coastal flood warnings.

TL;DR – October 10 Snapshot

  • Jerry: 50 mph tropical storm curving north, expected to weaken and turn post-tropical soon.

  • Karen: Subtropical storm weakening over the North Atlantic.

  • Nor’easter: Powerful non-tropical coastal storm developing off the Eastern U.S.—causing flooding, wind, and surf hazards through the weekend.

  • Gulf & Caribbean: Quiet.

  • Florida: No direct threats but increased surf.

Atlantic Hurricane Outlook – October 9, 2025

On October 9, Tropical Storm Jerry continues to strengthen in the central Atlantic with sustained winds near 65 mph. The storm is forecast to become a hurricane within 24–48 hours as it tracks west-northwest toward the northern Leeward Islands. Meanwhile, a disturbance in the Bay of Campeche carries only a 10% development chance. Florida and the Gulf of America remain calm aside from elevated surf and rip currents.

Tropical Storm Jerry continues west-northwest; likely intensification ahead; Gulf disturbance still low probability

Atlantic Basin Overview

  • Tropical Storm Jerry
    Jerry remains active in the Atlantic, located about 355 miles east-southeast of the northern Leeward Islands, moving west-northwest at ~20 mph, with sustained winds near 65 mph.
    The system is expected to strengthen into a hurricane by Friday or Saturday, as conditions favor further intensification.
    A tropical storm watch is in effect for islands such as Antigua, Barbuda, and St. Kitts as Jerry approaches.

  • Gulf / Bay of Campeche Disturbance
    A broad area of showers and thunderstorms continues in the Bay of Campeche with only a 10% chance of development per current outlooks over the next 48 hours and 7 days.

Environmental Conditions

  • Sea Surface Temperatures (SSTs):
    SSTs ahead of Jerry remain warm enough to support further strengthening into a hurricane, particularly over the central Atlantic.

  • Wind Shear:
    Moderate wind shear is present and may temper the rate of intensification, but not enough to prevent Jerry from likely becoming a hurricane under favorable alignment.

  • Humidity & Dry Air / SAL (Saharan Air Layer):
    Dry air and Saharan dust remain in portions of the eastern Atlantic, and these factors may limit convective expansion on Jerry’s flanks. The core appears better insulated from these effects currently.

Gulf of America & Caribbean

These regions remain relatively quiet. The Bay of Campeche disturbance is not expected to develop substantially, and no other tropical systems are showing strong signs of formation.

Florida & Eastern U.S. Forecast

Florida and the broader Eastern U.S. remain outside the immediate threat zone of Jerry. However:

  • Coastal and marine areas should remain alert for increasing surf, rip currents, and ocean swells as Jerry intensifies.

  • If Jerry curves northward later, Eastern U.S. coasts—especially the islands and the Leeward chain—could face tropical storm forces and heavy rain.

  • Inland Florida continues typical early-October weather: humidity, scattered storms, and localized downpours.

Rain forecast visualization courtesy of Windy.com

TL;DR – October 9 Snapshot

  • Jerry is intensifying, moving WNW, with top winds ~65 mph and is expected to become a hurricane soon.

  • The Bay of Campeche disturbance remains weak, with only 10% development odds.

  • SSTs support intensification; moderate shear and dry air may limit strength on the periphery.

  • Gulf of America and Caribbean remain calm.

  • Florida and U.S. East Coast currently face no direct land threat, but marine impacts are ongoing and may increase.

Atlantic Hurricane Outlook – October 8, 2025

On October 8, Tropical Storm Jerry has formed from Invest 95L in the central Atlantic and continues to strengthen on its west-northwest path toward the Leeward Islands. The National Hurricane Center has also noted a weak disturbance in the Bay of Campeche with only a 10% chance of development. Jerry remains no threat to Florida or the U.S. mainland, though dangerous surf and rip currents may develop along the East Coast as the storm intensifies.

Tropical Storm Jerry strengthens; Gulf disturbance has low odds of development

Atlantic Basin Overview

  • Tropical Storm Jerry
    The disturbance Invest 95L has now officially become Tropical Storm Jerry, located several hundred miles east-southeast of the northern Leeward Islands. Jerry continues its west-northwest track, and a tropical storm watch has been issued for parts of the northern Leeward Islands as the system is forecast to strengthen further.

  • Gulf / Bay of Campeche Disturbance
    A broad area of disorganized showers and thunderstorms persists over the Bay of Campeche. Some slow development is possible before the system moves inland over southern Mexico. However, the NHC currently assigns it only about a 10% chance of development over both the next 48 hours and 7 days.

Environmental Conditions

  • Sea Surface Temperatures (SSTs):
    SSTs ahead of Jerry remain warm enough (around 28–29 °C) to support continued intensification.

  • Wind Shear:
    Jerry is in a region of moderate shear which may slow rapid strengthening. If it can consolidate its core, further intensification is possible.

  • Humidity & Dry Air / SAL (Saharan Air Layer):
    Dry air and dust from the Saharan Air Layer are present across parts of the eastern Atlantic, which could limit convective coverage in Jerry’s outer bands.

Atlantic Hurricane Outlook – October 7, 2025

On October 7, Invest 95L continues to consolidate in the central Atlantic, now with a 90% chance of development according to the National Hurricane Center. The disturbance is likely to become a tropical depression or named storm within 24–48 hours as it moves west-northwest through warm 29–30°C waters. No immediate land threats are expected, and Florida and the Gulf of America remain calm.

Invest 95L shows rapid organization; 90% chance of tropical development in the central Atlantic

Atlantic Basin Overview

  • Invest 95L (High Chance of Development)
    The National Hurricane Center has increased development odds for Invest 95L to 90% over the next 7 days, as satellite imagery shows rapidly improving organization in the central tropical Atlantic, about halfway between the Cabo Verde Islands and the Lesser Antilles.

    The disturbance continues to consolidate with:
    • Expanding convection around a developing low-level center.
    • Stronger curvature in cloud bands.
    • Favorable oceanic and atmospheric support for intensification.

    If current trends persist, this system will likely become a tropical depression within 24–48 hours, and could be named Tropical Storm Jerry soon after.
    Model guidance continues to favor a west-northwest track through midweek, gradually turning more northwest by the weekend as it encounters subtropical steering.

    No immediate land threats are expected, though long-range trends will be monitored closely for potential shifts toward the western Atlantic later this week.

  • Other Atlantic Activity
    No additional organized systems are currently being monitored.

Environmental Conditions

  • Sea Surface Temperatures (SSTs):
    SSTs in the central Atlantic remain very warm (29–30 °C) — more than sufficient to support strengthening if the disturbance maintains convection.

  • Wind Shear:
    The system is positioned in a region of low to moderate vertical wind shear (10–15 kt), favorable for gradual intensification over the next few days. Shear may increase slightly later in the week as the system moves northwest.

  • Humidity & Dry Air / SAL:
    Moisture levels have improved, and the surrounding Saharan Air Layer (SAL) has thinned significantly, creating a more favorable pocket for development. Only minor dry air entrainment remains on the northern flank of the disturbance.

Atlantic Hurricane Outlook – October 6, 2025

On October 6, a tropical disturbance in the central Atlantic maintains a 70% chance of development according to the National Hurricane Center. The system remains disorganized but is moving through warm waters conducive to gradual formation. Environmental factors like dry air and moderate wind shear are slowing intensification. Florida and the Gulf of America remain free of direct tropical threats.

No active tropical systems; a disturbance in the central Atlantic bears watching

Atlantic Basin Overview

  • No Active Tropical Cyclones
    Currently there are no named storms or hurricanes in the Atlantic, Caribbean, or Gulf of America per the latest NHC outlook.

  • Disturbance Under Monitoring
    The NHC continues to track a tropical wave / disturbance in the central Atlantic with increasing organization and favorable parameters. This system retains a 70% chance of tropical development over the next 7 days as earlier reported.

Environmental Conditions

  • Sea Surface Temperatures (SSTs):
    SSTs across much of the tropical Atlantic and the disturbance’s projected path remain warm, generally supportive for development if other conditions align.

  • Wind Shear:
    Elevated vertical wind shear remains a limiting factor across broad parts of the Atlantic. That shear may slow intensification or disrupt organization of the monitored disturbance.

  • Humidity & Dry Air / SAL:
    Mid-level dry air and Saharan dust intrusions persist in portions of the basin. Those dry air inclusions and SAL effects continue to suppress convective vigor in developing systems, especially farther east.

Atlantic Hurricane Outlook – October 5, 2025

On October 5, a tropical disturbance in the central Atlantic is showing improved organization and now carries a 70% chance of development according to the National Hurricane Center. The system may become a tropical depression or storm early this week as it moves west-northwest across warm waters. Imelda’s remnants continue to fade, and the Gulf of America and Florida remain quiet aside from minor marine impacts.

Tropical disturbance in central Atlantic gains strength; 70% development chance in coming days

Atlantic Basin Overview

  • Invest Area – Central Atlantic Disturbance (High Chance of Formation)
    The National Hurricane Center is closely monitoring a well-defined tropical wave located in the central tropical Atlantic, roughly halfway between the Cabo Verde Islands and the Lesser Antilles.

    The system has shown improving organization over the past 24 hours with:
    • Persistent clusters of deep convection.
    • Increasing low-level rotation visible in satellite imagery.
    • A pocket of lighter wind shear and higher mid-level humidity supporting development.

    The NHC now gives this system a 70% chance of tropical cyclone formation within 7 days, and it may become a tropical depression or storm early this week as it moves west-northwest at 10–15 mph across warm 29–30 °C waters.

    Long-range model guidance suggests the system will stay well east of the Caribbean for the next 5 days, though trends bear monitoring.

  • Post-Tropical Imelda
    Imelda remains a strong post-tropical cyclone over the open Atlantic. It is racing east-northeast and poses no threat to land, though it continues to generate residual swell and rough seas over parts of the North Atlantic.

  • Other Waves / Disturbances
    No additional organized systems are present. A weak wave emerging from western Africa remains broad and disorganized under dry air.

Environmental Conditions

  • Sea Surface Temperatures (SSTs):
    SSTs across the central and western tropical Atlantic remain above average (29–30 °C), easily supportive of development if convection persists.

  • Wind Shear:
    The disturbance lies in a localized pocket of lower shear (10–15 kt), which is helping convection consolidate. Stronger shear farther west may slow development later in the week.

  • Humidity & Dry Air / SAL:
    The Saharan Air Layer (SAL) continues to influence the eastern Atlantic but has weakened around the current disturbance. Improved mid-level moisture is aiding its gradual organization.

Atlantic Hurricane Outlook – October 3, 2025

On October 3, Imelda has transitioned into a post-tropical cyclone while racing east-northeast after impacting Bermuda. While no longer tropical, Imelda continues to drive dangerous swells and rip currents along the U.S. East Coast. Humberto has dissipated, and other Atlantic disturbances remain suppressed by dry air and wind shear. Florida and the Gulf of America remain free of direct tropical threats.

Imelda now post-tropical, swells and rip currents remain key concern for East Coast

Atlantic Basin Overview

  • Post-Tropical Imelda
    Imelda has transitioned to a post-tropical cyclone after passing near Bermuda. While it no longer maintains full tropical structure, it continues to generate strong winds, rain, and ocean swell. Impacts are now mostly marine and coastal in nature rather than landfall risks.

  • Humberto & Other Waves
    Humberto has lost tropical characteristics and merged with mid-latitude systems, but its residual energy still contributes to elevated surf and rip current conditions along the U.S. East Coast. Other Atlantic disturbances remain weak and suppressed by environmental constraints.

Environmental Conditions

  • Sea Surface Temperatures (SSTs):
    SSTs beneath Imelda’s path remain moderately warm, but cooler waters ahead are aiding its weakening and limiting further tropical regeneration.

  • Wind Shear:
    Increasing vertical wind shear is disrupting Imelda’s convection and hastening its transition away from tropical structure.

  • Humidity & Dry Air / SAL:
    Dry mid-level air and Saharan dust continue to intrude, especially around weaker disturbances, suppressing convective activity and impeding new development.

Florida & Eastern U.S. Forecast

Florida will remain outside the core of Imelda, though elevated surf, swell, and rip current conditions persist along Atlantic beaches. The broader Eastern U.S. coast should continue to monitor marine impacts and occasional squalls driven by Imelda’s remnants.

Rain forecast visualization courtesy of Windy.com

TL;DR – October 3 Snapshot

  • Imelda is now post-tropical but still influencing coastal waters.

  • Humberto has transitioned to an extratropical system, but contributes to marine hazards.

  • Environmental factors (cooling waters, shear, dry air) continue to weaken Imelda and suppress new development.

  • Gulf and Caribbean remain quiet.

  • East Coast marine impacts (surf, rip currents) are the primary hazard now.

Atlantic Hurricane Outlook – October 2, 2025

On October 2, Hurricane Imelda has weakened to Category 1 while racing east-northeast away from Bermuda after bringing damaging winds and power outages to the island. Humberto has transitioned into an extratropical system, but swells and rip currents will persist along the U.S. East Coast. Environmental factors—cooler waters, rising wind shear, and Saharan dust—are driving Imelda’s decline and limiting new development. Florida and the Gulf of America remain quiet.

Imelda weaker but still impactful; Humberto dissipates; hazardous marine conditions persist

Atlantic Basin Overview

  • Hurricane Imelda
    Imelda passed near Bermuda, causing widespread power outages, downed trees, and strong winds. It has since weakened to Category 1 status with sustained winds near 80 mph and is moving east-northeast at 30 mph. No U.S. landfall is expected as Imelda continues to track away.

  • Hurricane Humberto
    Humberto has merged with frontal systems and lost tropical characteristics, transitioning into an extratropical cyclone. Its circulation is no longer classified as a hurricane, though its remnant energy continues contributing to swells and marine hazards along the Atlantic.

  • Other Disturbances / Waves
    Additional Atlantic waves are being watched, but none currently show robust development or trajectories toward U.S. coasts under present forecasts.

Environmental Conditions

  • Sea Surface Temperatures (SSTs):
    SSTs near Imelda and Bermuda remain warm enough to support tropical cyclone strength, but cooler waters lie ahead along its projected path, which will continue to weaken it.

  • Wind Shear:
    Vertical wind shear is increasing across Imelda’s circulation, eroding convection and weakening structural organization.

  • Humidity & Dry Air / SAL:

Atlantic Hurricane Outlook – October 1, 2025

On October 1, Hurricane Imelda has strengthened to 90 mph as it accelerates toward Bermuda, where a hurricane warning is in effect. The storm is forecast to bring damaging winds, heavy rain, and coastal flooding to the island tonight. Meanwhile, Humberto remains offshore, producing hazardous surf and rip currents across the Atlantic. Environmental conditions—warmer SSTs but rising shear and Saharan dust—support Imelda’s current strength but will limit its future intensification. Florida and the Gulf of America remain calm.

Imelda attains hurricane strength en route to Bermuda; Humberto adds to oceanic hazards

Atlantic Basin Overview

  • Hurricane Imelda
    As of 8:00 AM EDT, Imelda is located near 30.7°N, 71.3°W, about 395 miles west-southwest of Bermuda. It’s moving east-northeast at 21 mph with maximum sustained winds around 90 mph and a central pressure near 974 mb. A hurricane warning remains in effect for Bermuda. Imelda’s core is expected to pass near or over Bermuda tonight before heading away.

  • Hurricane Humberto & Other Disturbances
    Humberto remains active farther east in the Atlantic, contributing to dangerous marine conditions (swells, rip currents) that extend toward the U.S. East Coast. No new significant tropical developments are imminent per the latest outlooks.

Hurricane Imelda

Environmental Conditions

  • Sea Surface Temperatures (SSTs):
    SSTs along Imelda’s projected track remain warm enough to support hurricane intensity as it approaches Bermuda, though cooler waters ahead will begin to weaken it over time.

  • Wind Shear:
    Moderate to increasing shear is expected, especially as Imelda accelerates east-northeast. This shear will work against further intensification and eventually strip its convection.

  • Humidity & Dry Air / Saharan Air Layer (SAL):
    Dry mid-level air and dust intrusions from the Saharan Air Layer continue to challenge Imelda’s outer circulation. These environmental suppressors reduce convective vigor, particularly in its outer bands. The combined influence of shear and dry air will limit how strong Imelda can become.

Atlantic Hurricane Outlook – September 24, 2025

On September 24, Hurricane Gabrielle is a powerful Category 3 storm moving east-northeast toward the Azores, where a hurricane warning is in effect. While no direct landfall is expected in the U.S., Gabrielle’s swells are producing dangerous surf and rip currents along the East Coast. Other Atlantic disturbances remain suppressed by wind shear, dry air, and Saharan dust. Florida and the Gulf of America remain calm, experiencing only late-summer heat, humidity, and afternoon thunderstorms.

Gabrielle weakens slightly but remains a major hurricane as it approaches the Azores; East Coast seas stay rough

Atlantic Basin Overview

  • Hurricane Gabrielle
    Gabrielle is now a Category 3 hurricane with maximum sustained winds near 115 mph. It is centered at 35.8° N, 50.2° W, moving east-northeast at about 25 mph. The storm is expected to weaken gradually as it encounters cooler waters, but it remains dangerous. A hurricane warning is in effect for the Azores, where Gabrielle will pass over or very near the islands late Thursday into Friday.

    Swells from Gabrielle continue to spread westward, producing life-threatening surf and rip currents across Bermuda, the U.S. East Coast from the Carolinas through New England, and into Atlantic Canada.

  • Other Waves / Disturbances
    The NHC is monitoring additional tropical waves across the Atlantic. None are currently well-organized, and environmental conditions are limiting immediate development. Forecast guidance suggests these waves are not a threat to the Eastern U.S. coastline in the near term.

Environmental Conditions

  • Sea Surface Temperatures (SSTs): SSTs beneath Gabrielle remain warm enough to support a major hurricane, but cooler waters lie ahead along its northeastward track, which will drive weakening in the coming days.

  • Wind Shear: Vertical wind shear is beginning to increase, disrupting Gabrielle’s inner core and capping further rapid strengthening. The eastern Atlantic waves are also encountering moderate to high shear, preventing better organization.

  • Humidity & Dry Air (SAL): Pockets of mid-level dry air and dust from the Saharan Air Layer are feeding into parts of Gabrielle’s circulation and heavily suppressing convection for the monitored waves farther east. This continues to be a key factor in limiting new development.

Atlantic Hurricane Outlook – September 23, 2025

On September 23, Hurricane Gabrielle is at Category 4 strength with winds near 140 mph as it moves northeast over the open Atlantic. While no direct land impacts are expected, Gabrielle is producing hazardous surf and rip currents along the Eastern Seaboard. The NHC is monitoring two waves in the Atlantic with medium to high development potential over the next week. Florida and the Gulf of America remain quiet with only routine late-summer weather.

Hurricane Gabrielle peaks as a powerful Category 4 storm; two waves being monitored

Atlantic Basin Overview

  • Hurricane Gabrielle
    Gabrielle has reached Category 4 intensity with sustained winds near 140 mph. It is centered east-northeast of Bermuda, moving northeast at ~13 mph. The system is expected to remain a powerful hurricane through Tuesday before gradually weakening as it tracks into cooler waters. No direct land impacts are forecast, though Gabrielle is generating dangerous swells and rip currents along the U.S. East Coast.

  • Other Tropical Waves / Disturbances
    The NHC is monitoring two waves in the central and eastern Atlantic:
    • A disturbance about 1,000 miles east of the Lesser Antilles has a high chance (~80%) of development over 7 days.
    • A second wave, east of the Leeward Islands, has a medium chance (~50% over 7 days), though it remains disorganized.
    Both systems are expected to track generally west-northwest, with no immediate threat to the Eastern U.S. coastline.

Environmental Conditions

  • Sea Surface Temperatures (SSTs): Warm waters in the central Atlantic continue to support Gabrielle’s intensity, while also providing fuel for the two monitored disturbances.

  • Wind Shear: Gabrielle is beginning to encounter stronger upper-level wind shear, which should promote gradual weakening. Moderate shear is also affecting the waves farther east, slowing their organization.

  • Humidity & Dry Air (SAL): Mid-level dry air and Saharan Air Layer dust are suppressing convection in the eastern Atlantic, limiting the short-term development potential of the monitored waves.
