Atlantic Hurricane Outlook – August 10, 2025: Multiple tropical waves crossing the Atlantic; development chances gaining

Multiple tropical waves are moving across the Atlantic today, but Saharan dust, wind shear, and dry air are keeping development chances low. Warm ocean temperatures could allow for changes later this week.

Atlantic Basin Overview

TLDR Version; Jump Here

As of this morning, no named tropical cyclones are active in the Atlantic. Several tropical waves are traveling westward across the Main Development Region (MDR), but most are struggling with environmental challenges that limit development. Sea surface temperatures are amply warm, so these waves will continue to be monitored as they move toward more favorable conditions later this week.

Key Systems We’re Watching

  • Central Atlantic Tropical Wave (~40°W):
    Moving west at 10–15 knots with scattered convection. Organization remains limited due to dry air and moderate wind shear. Low chance of development over the next 7 days.

  • Eastern Atlantic Tropical Wave (~23°W, off Africa):
    Recently emerged from the continent with convection along its southern flank. Battling Saharan dust and dry air, keeping development chances low in the near term, potentially gaining strength in next 7-days.

  • Monsoon Trough Low (~08N44W):
    Embedded within the monsoon trough, sparking intermittent thunderstorm activity. No immediate signs of organized development.

Environmental Conditions

  • Sea Surface Temperatures (SSTs):
    MDR running 28–29.5°C (82–85°F), with 29–31°C (84–88°F) in the Caribbean and Gulf of Mexico—plenty of fuel for storms if other conditions improve.

  • Wind Shear:
    Moderate to high shear in the central Atlantic is tilting storm structures and preventing vertical stacking of thunderstorms, slowing development.

  • Moisture:
    Humidity is increasing in the western tropical Atlantic, but dry air still lingers across much of the MDR.

  • Saharan Air Layer (SAL):
    Dry, dusty air extends across the eastern and central MDR, suppressing convection and capping short-term development potential.

Atlantic Hurricane Outlook – August 6, 2025: Dexter Weakens Over Open Atlantic; Two Systems Now Under Watch

Tropical Storm Dexter continues weakening in the open Atlantic, while two systems—off the Southeast U.S. coast and near Africa—are now under watch. SAL and wind shear are still limiting major development, but warm SSTs raise future potential.

*Those who like data, continue reading. Those it prefer the quick version, jump to the TL;DR here.

Tropical Storm Dexter continues moving northeast and weakening, while the National Hurricane Center is now monitoring two additional disturbances—one off the Southeast U.S. coast and another tropical wave across the eastern Atlantic—with modest development potential over the coming week.

Atlantic Basin Status

  • Tropical Storm Dexter is currently well north of Bermuda, sustained winds near 40–45 mph, moving east-northeast at ~13 mph. It's expected to transition to a post-tropical cyclone by mid-week and present no threat to land.

  • Disturbance near Southeast U.S. coast (“Invest AL95”): Located offshore of Florida, now has a 40% development chance over the next 7 days. While significant intensification is unlikely, it may bring increased rain and marine impacts along the Mid-Atlantic and Southeast coastal areas.

  • Tropical wave near ~30°W off Africa: Moving west-northwest, scattered convection observed. NHC assigns a 50% chance of development within 7 days, as it enters warmer seas and potentially weaker shear zones.

Key Environmental Conditions

  • Sea Surface Temperatures (SSTs): Gulf and Caribbean waters remain very warm (29–31 °C), offering the thermal fuel necessary for storm development as conditions evolve.

  • Wind Shear: Moderate to high shear prevails across much of the central Atlantic, limiting organization of existing systems. Models hint that shear may ease near the western MDR later this month.

  • Saharan Air Layer (SAL): A dry, dusty SAL plume still covers much of the eastern and central Atlantic, suppressing mid- to upper-level moisture and inhibiting thunderstorm persistence.

  • Atmospheric Moisture: Improving across the western basin, especially near the Caribbean, though heavy dry air remains in many parts of the Atlantic.

Atlantic Hurricane Outlook – August 5, 2025: Dexter Weakening, Two Other Areas Monitored

Tropical Storm Dexter weakens far from land, while two other systems—one off Africa and one near the Southeast U.S.—are being watched. Although development chances remain modest, conditions are expected to become more favorable later this month.

Tropical Storm Dexter is slowly weakening but not yet dissipated, while two additional disturbances now carry up to a 30–50% chance of development within the next week. Environmental conditions remain a limiting factor for most areas, but shift slowly toward greater activity as August progresses.

Atlantic Basin Summary

Tropical Storm Dexter
Located roughly 250–275 miles north-northwest of Bermuda, Dexter has maximum sustained winds near 45 mph and is moving northeast at ~12–15 mph. While it is weakening, it may reintensify as a post-tropical cyclone late this week, posing no direct land threat.

Other Areas Under Watch

  • A low-pressure area offshore of the Southeast U.S. (Invest AL95) carries a 30% chance of development over 7 days. Slight organization is possible as it moves eastward, but land impacts are unlikely.

  • A tropical wave near ~30°W off Africa shows scattered convection and is assigned a 50% chance of development within 7 days, reflecting improving model support.

Key Environmental Conditions

*In the upper right corner of the below screens, toggle with the +/- icons

  • Sea Surface Temperatures (SSTs):
    Gulf of Mexico, Caribbean, and MDR waters range between 29–31 °C (84–88 °F)—ample heat energy for storm formation if atmospheric conditions cooperate.

  • Wind Shear:
    Wind shear remains moderate to high across much of the Atlantic, especially in the central basin, limiting storm organization despite occasional lower-shear pockets emerging near the western Gulf.

Atlantic Hurricane Outlook – August 3, 2025: Two Areas Now Under Watch

The Atlantic remains calm with no named storms, but two areas—one off the U.S. coast and another off Africa—are now under watch for potential tropical development. Here's today's scientific hurricane outlook.

*Those who like data, continue reading. Those it prefer the quick version, jump to the TL;DR here.

As early August continues, the Atlantic remains without any active tropical cyclones. However, two areas have emerged as brown disturbance watches, as forecasters monitor subtle signs that could impact the Atlantic if conditions shift.

Atlantic Basin Highlights

  • No active tropical storms in the basin.

  • Two areas are now under National Hurricane Center scrutiny:

    Invest Area AL95: Expected to be a fish storm, it’s a non-tropical low just off the North Carolina coast—producing disorganized thunderstorms. (The orange X on the chart)
    Chance of development: Medium (30%) over the next 2–7 days.
    Movement: Toward the east-northeast at ~10 mph, expected to stay offshore.

    Emerging tropical wave off Africa: Near 30°W, forecast to move westward with scattered convection.
    Chance of development: Low (30%) within 7 days.

GOES-19 - Sector view: North Atlantic - Sandwich - August 3, 2025

GOES-19 - Sector view: Tropical Atlantic - Sandwich - August 3, 2025

Key Environmental Conditions

  • Sea Surface Temperatures (SSTs):
    The Gulf of Mexico and Caribbean Sea remain very warm, with temperatures ranging from 29–31°C (84–88°F). The Main Development Region (MDR) is also running slightly above average. These warm waters provide abundant fuel for tropical development — if other atmospheric factors allow.

  • Wind Shear:
    Moderate to high vertical wind shear persists across the central Atlantic, particularly along the latitude band where Disturbance 2 is located. This disrupts the vertical alignment of developing systems and limits the ability of convection to consolidate around a center.

  • Moisture:
    Mid-level moisture is gradually increasing across the western tropical Atlantic and Caribbean. However, the central Atlantic remains drier overall, especially in areas affected by Saharan dust, limiting deep convection and thunderstorm persistence.

  • Saharan Air Layer (SAL):
    A robust SAL is sweeping across the central and eastern Atlantic, characterized by dry, dusty air and suppressed vertical motion. The SAL also contributes to a stable atmosphere, effectively capping thunderstorm development and working against tropical wave organization.

Dust & SAL data from Windy.com

Implication for Disturbance 2:

While ocean temperatures are favorable, the combined influence of high wind shear, limited moisture, and widespread SAL intrusion is expected to stall or inhibit further development of Disturbance 2 as it continues westward across the tropical Atlantic. Until it reaches a more favorable environment, organization remains unlikely.

Gulf of America (Mexico) & Caribbean Region

  • No disturbances active in the Gulf, and high-pressure conditions support light winds and minimal rain outside normal sea‑breeze showers.

  • Eastern Caribbean: A wave near 68°W is producing localized storms over Hispaniola and Venezuela but remains disorganized.

Atlantic Hurricane Outlook – July 22, 2025: Tropics Stirring, But Development Remains Gradual

Tropical activity is picking up across the Atlantic, with multiple waves being monitored. While no storms are expected yet, conditions are slowly becoming more favorable for development.

The Atlantic basin remains free of named storms this morning, but the deep tropics are showing increased activity. Multiple tropical waves are marching across the basin—some with disorganized convection, others with early signs of circulation. While none are forecast to develop imminently, the atmospheric stage is being set for a more active period as we approach late July.

Atlantic Basin: Several Waves Under Watch

As of the 8:00 AM EDT Tropical Weather Outlook from the National Hurricane Center (NHC):

  • No active tropical cyclones

  • Two tropical waves of interest:

    • Central Atlantic wave near 45°W: Still disorganized, no longer showing on NOAA Seven-Day TWO , moving westward at 10–15 knots. Scattered convection continues, and models suggest a more favorable environment as it approaches the Caribbean later this week.
      Chance of development over 7 days: Low (20%)

    • Far Eastern Atlantic wave near 27°W: Recently emerged off Africa. Some associated convection along its southern flank, but no signs of organization yet.

Both systems are embedded in the broader Monsoon Trough, which is supporting shower and thunderstorm development across the deep tropics.

Sea Surface Temperatures: Favorable and Climbing

Ocean waters remain well above average in key areas:

  • Gulf of Mexico: 86–90°F (30–32°C) across most of the basin

  • Western Caribbean: Steady warming, ideal for storm fuel

  • Main Development Region (MDR): 1–2°C above normal across much of the eastern and central Atlantic

These conditions provide a supportive foundation for any systems that organize over the coming weeks.

Wind Shear and Atmospheric Conditions: Mixed Signals

Wind Shear Courtesy of https://tropic.ssec.wisc.edu/

  • Wind shear is moderate across much of the Caribbean and central Atlantic, but is beginning to weaken in pockets—especially south of 20°N.

  • Moisture levels in the mid and lower atmosphere continue to rise, supporting the recent uptick in convection.

  • Dry air from the Saharan Air Layer (SAL) still lingers across parts of the eastern Atlantic but is beginning to fragment—reducing one of the main inhibitors to development.

Thunderstorm Activity: Widespread in the Deep Tropics

Clusters of convection are active:

  • Along the monsoon trough from 10°N to 15°N between 25°W and 50°W

  • In the western Caribbean, especially south of Jamaica, where upper-level support is creating isolated thunderstorms

  • Over Central America and the Yucatán Peninsula, where diurnal heat is triggering inland storms

These are not organized tropical systems—but they reflect a broader shift toward a more favorable convective environment.

Florida Forecast: Hot, Humid, and Stormy

Expect a classic Florida summer day:

  • North Florida: Highs in the upper 80s to low 90s°F, scattered PM storms

  • Central Florida: Around 91°F with heat index nearing 102°F; thunderstorms likely between 2–7 PM

  • South Florida: Mid-to-upper 80s, muggy, with pockets of heavy rainfall inland

Localized flooding is possible in low-lying areas during heavy downpours.

Prep Tip of the Day: Recheck Insurance Coverage

Use this quiet window to review your insurance:

  • Verify your hurricane deductible and coverage limits

  • Make sure flood insurance is in place—it typically has a 30-day waiting period

  • Store digital copies of policies in a secure cloud folder

  • Photograph your home’s exterior and interior for pre-storm documentation

Looking Ahead: No Immediate Threats, But the Tropics Are Heating Up

While no storms are expected in the next 48 hours, the increasing wave activity, warm ocean waters, and weakening SAL suggest the tropics are transitioning into a more active phase. Late July into early August is a known ramp-up period for development.

Stay alert, stay ready, and check back tomorrow for your Cat5Prep.com hurricane update.

Atlantic Hurricane Outlook – July 21, 2025: Tropics Active with Waves, But No Imminent Threats

The Atlantic remains cyclone-free, but several tropical waves are moving across the basin. Conditions are gradually becoming more favorable for development as July progresses.

The tropical Atlantic is becoming increasingly active, with multiple tropical waves progressing westward across the basin. While none are expected to develop in the short term, the setup is a reminder that we are entering a more climatologically favorable period for storm formation.

Atlantic Basin Overview: No Cyclones, But Multiple Waves

As of the 8:00 AM EDT update from the National Hurricane Center:

  • No active tropical cyclones

  • No systems with high development potential at this time

  • Disturbance 1: A tropical wave near 40°W is producing scattered convection, but environmental conditions remain only marginally favorable.

    • Formation chance (7 days): 20%

    • Movement: West to west-northwest at 10–15 mph

  • New Wave Introduced: A second tropical wave near 23°W, just offshore of Africa, is showing scattered moderate convection on its southern flank.

    • Too early to determine development potential, but it will be watched over the coming days.

  • Monsoon Trough Low: A weak low embedded along the monsoon trough near 08N44W is sparking convection, but not currently organized.
