Atlantic Hurricane Outlook – August 9, 2025: Quiet Tropics with More Waves Brewing

Tropics stay quiet as Invest 96L weakens, but a fresh African wave is gaining attention with a 30% development chance in the next week. Peak season conditions are setting up.

*TLDR Version, Jump Here!


The Atlantic remains calm, but early signs indicate a potential ramp-up in activity. One tropical wave is weakening, while another emerging off Africa is attracting attention due to improving environmental conditions.

Atlantic Basin Overview

  • Invest AL96 (Central Atlantic):
    The tropical wave associated with AL96 has seen its convection collapse in recent days, largely due to dry, Saharan-influenced air. Development chances remain low at 0–2 days, though gradual organization may become possible in the middle of next week as the system moves northwestward .

  • New African Tropical Wave:
    A fresh tropical wave just exiting the African coast has been designated an area of interest. The NHC currently assigns a 30% chance of development over the next 7 days. Long-range models depict a perhaps more favorable environment, suggesting potential development beyond a week and possible impacts in the eastern Caribbean around August 16–17.

Atlantic Hurricane Outlook – August 4, 2025: Tropical Storm Dexter Forms; Two Other Systems Under Watch

Tropical Storm Dexter forms off the East Coast with no land threat. Meanwhile, a tropical wave off Africa and a low near the Southeast U.S. are being monitored as conditions slowly shift toward a more active period.

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

Tropical Storm Dexter has developed in the western Atlantic, while two additional systems are being monitored for potential development. Conditions across the basin remain dynamic—with storm formation possible in coming days.

Atlantic Basin Summary

  • Tropical Storm Dexter: The fourth named storm of the 2025 season formed late Sunday night, now located ~255 miles northwest of Bermuda. Maximum sustained winds are 45 mph, and the system is moving east-northeast. It’s expected to remain over open water and become post-tropical by Wednesday with no threat to U.S. land.

  • Disturbance AL95: A non-tropical low pressure area off the Southeast U.S. coast is being monitored with medium (30%) development chance over 7 days. Movement is east-northeast under weak shear, and formation may remain offshore.

  • New tropical wave emerging off Africa (~30°W): Forecast to track westward with scattered convection. The formation chance is 50% over 7 days, indicating growing potential for a tropical depression if favorable conditions develop.

Environmental Conditions

  • Sea Surface Temperatures (SSTs):
    Waters in the Gulf of Mexico, Caribbean, and MDR remain warm at 29–31°C (84–88°F)—providing ample energy if atmospheric conditions become supportive.

  • Wind Shear:
    Still moderate to high across much of the Atlantic, limiting vertical storm structure. However, shear may relax in the western basin later this month.

  • Saharan Air Layer (SAL):
    Persistent dry, dusty air continues to suppress convection, especially over the eastern and central Atlantic. This remains a major inhibiting factor for newly emerging systems.

  • Moisture:
    Improving moisture levels seen in the western Caribbean and Gulf, though much of the basin remains too dry for sustained disturbance development.

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.

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.

Meteorological models forecast these systems might strengthen if wind shear declines and dust regresses later this month.

TL;DR – August 3 Hurricane Summary

  • No storms currently in the Atlantic basin.

  • AL95 (off North Carolina): 30% chance of development over the next week. (Fish Storm)

  • African wave near 30°W: 20% chance of development within 7 days.

  • Factors are currently favoring disorganization.

  • SSTs are warm and moisture is increasing—conditions may improve in early August.

  • Immediate risk remains low; now is a good window for storm preparedness.

Atlantic Hurricane Outlook – July 19, 2025: Disturbance in the Deep Tropics Eyes Development

A tropical wave southwest of the Cabo Verde Islands shows a low chance of development as it moves westward. Conditions remain mixed across the Atlantic, but signs of activity are increasing.

The Atlantic Basin remains relatively quiet today, but there’s a new player on the map. A tropical wave in the central tropical Atlantic—labeled Disturbance 1—has a low but notable chance of development over the next week. This marks the first sign of deeper tropical activity emerging from the Main Development Region (MDR) as we move closer to peak hurricane season.

Atlantic Basin Overview: One Area to Watch

As of 8:00 AM EDT Saturday, July 19, 2025, the National Hurricane Center is monitoring:

  • No named tropical cyclones

  • One disturbance in the central Atlantic

  • Tropical development chances:

    • 10% over 48 hours

    • 20% over 7 days

Disturbance 1 is a tropical wave located about 900 miles west-southwest of the Cabo Verde Islands, interacting with a broad area of low pressure. Showers and thunderstorms remain disorganized, but marginally favorable conditions could support slow development as the system moves west to west-northwest around 10 mph.

However, by mid-week, environmental conditions are expected to become less favorable, limiting its window for intensification.

Sea Surface Temperatures: Fuel in Place

Waters remain very warm across much of the Atlantic:

  • Gulf of Mexico: Holding above 86°F (30°C) in many areas

  • Western Caribbean: High SSTs remain steady

  • Main Development Region (MDR): Warm enough to support tropical wave development—an important factor as more systems emerge off Africa

These warm waters are key to supporting systems like Disturbance 1.

Sea Surface Temperature data courtesy of Windy.com

Wind Shear & Moisture: Still Mixed

  • Wind Shear: Moderate in the eastern Atlantic near Disturbance 1 but lower closer to the Caribbean

  • Moisture: Rising across the western Atlantic, but dry air from the Saharan Air Layer (SAL) is still suppressing deeper convection across much of the MDR

While the disturbance has some support for development, these mixed upper-atmospheric conditions could limit growth.

  • Rain: 60–70% chance of scattered storms in parts of Florida, especially in the afternoon and evening

  • Winds: Light southeast winds, with occasional gusts during storms

Prep Tip of the Day: Review Flood Insurance Coverage

Standard homeowners insurance does not cover flood damage. Use this calm window to:

  • Check your flood zone designation

  • Review your current policy limits

  • Confirm your coverage start date (flood insurance usually has a 30-day waiting period)

With warm SSTs and an increasingly favorable atmosphere, inland and coastal flood risk rises as we move deeper into hurricane season.

Looking Ahead: Watchful, Not Worrying

Although July 16 brings no immediate storm threats, all eyes remain on the broader Atlantic:

  • The ingredients for development are aligning: warm water, weakening shear, and increased moisture.

  • The next two weeks may see the first organized systems forming in the western Caribbean or Gulf of Mexico.

Now is the time to stay informed and finalize preparations—not when a storm is already on the map.

Atlantic Hurricane Outlook – June 20, 2025: Tropics Hold Quiet as Atlantic Patterns Begin to Shift

The Atlantic remains calm with no storms expected, but warm waters and shifting atmospheric patterns hint that the quiet may not last. A developing Atlantic Niña could hit a reversal and amplify activity later this season.

As we close out the third week of the 2025 Atlantic hurricane season, the basin remains quiet. No named storms or tropical disturbances are being monitored by the National Hurricane Center (NHC), and no development is expected over the next 7 days. However, behind this calm lies a subtle shift in Atlantic patterns that may influence storm activity in the weeks ahead.

Daily Hurricane Update June 20, 2025 with Hurricane formation in the Atlantic being suppressed by Atlantic Niña

Atlantic Basin: All Clear—for Now

As of the latest NHC update (8 AM EDT, June 20):

  • No active tropical cyclones

  • No areas of interest

  • No tropical development expected through late June

This type of quiet is typical for mid-June, historically a transitional period before activity ramps up in July and peaks from August to October.

Sea Surface Temperatures: Still Hot, Still Fuel

Sea surface temperatures (SSTs) across much of the Atlantic remain well above normal:

  • Gulf of America (Mexico): Mid to upper 80s°F (29–31°C), 2–4°F above average

  • Western Caribbean: Similar anomalies, particularly near the Yucatán and Cuba

  • Main Development Region (MDR): Still warming gradually, trending toward conditions that could support long-track storms later this season

Warm SSTs are a critical energy source for hurricanes—and the heat is already in place.

Sea Surface Temperature (ECMWF Analysis) via Windy.com

Atmospheric Conditions: Neutral ENSO, but Atlantic Cooling Briefly

While the Pacific remains in an ENSO-neutral phase, a rare “Atlantic Niña” has recently emerged—marked by cooler-than-average sea surface temperatures in the eastern tropical Atlantic off the coast of Africa, as seen in the NOAA Coral Reef Watch chart below with a pocket of blue.

  • This can temporarily suppress early-season hurricane formation by reducing convection and stabilizing the atmosphere

  • However, models indicate that this pattern may reverse in July, shifting into a warmer Atlantic Niño phase, which typically boosts tropical activity

So, while the Atlantic Niña may be limiting development now, forecasters are closely watching the timing of this transition. Safe money would be on a reversal, which could super charge storm breeding.

Thunderstorm Activity: Mostly Seasonal and Local

While no tropical organization is underway, convection continues to pop up in key regions:

  • Florida and Gulf Coast: Afternoon storms due to heat and humidity

  • Western Caribbean: Scattered convection, but unorganized

  • Eastern Atlantic: A few tropical waves exiting Africa remain weak and embedded in dry air

These thunderstorms are typical for the season and do not currently show signs of tropical development.

Thunderstorm Forecast (ECMWF) via Windy.com

Florida Forecast

  • Highs: Upper 80s to low 90s°F (31–33°C)

  • Humidity: High

  • Afternoon Storms: Scattered area of thunderstorms likely after 2 PM

  • Winds: Light and variable, with storm gusts possible

Flooding in low-lying areas is possible if storms linger over one area.

Prep Tip of the Day: Restock Pet Supplies

Don’t forget your furry family members when preparing for hurricane season:

  • Have a two-week supply of pet food, medications, and water

  • Keep vaccination records and vet contact info in your go-bag

  • Prepare a small pet first-aid kit

  • Label pet carriers clearly and store them where they’re easy to grab

Looking Ahead: Transition Coming

For now, the Atlantic basin is calm. But forecasters continue to watch:

  • Warm SSTs

  • Easing wind shear

  • Gradual return of moisture

  • Potential reversal from Atlantic Niña to Atlantic Niño

All signs point to a more active environment forming as we move into July. Stay alert, stay prepared, and check back tomorrow for your daily hurricane outlook from Cat5Prep.com.

Atlantic Hurricane Outlook – June 19, 2025: Still Down South – Pacific Watches Erick

The Atlantic remains storm-free, but Hurricane Erick—a powerful Category 4 storm—gains strength in the Eastern Pacific. Learn what this means for the Atlantic basin and why now is the time to prepare.

The Atlantic basin remains quiet today, with no active tropical cyclones and no development expected over the next 7 days, according to the National Hurricane Center’s latest 2 AM and 8 AM EDT outlooks nhc.noaa.gov. While the Atlantic sleeps, attention is turning to a powerful system in the Pacific.

Atlantic Basin: Calm Waters, No Alerts

There are still no named storms or areas under tropical monitoring. The graphical and textual 7-day outlooks show zero development chance, meaning the basin continues its quiet stretch early in the season . Early June silence isn’t unusual—but with warm seas in place, conditions could shift quickly.

Pacific Perspective: Erick Now a Category 4

In the Eastern Pacific, Hurricane Erick has rapidly intensified into an “extremely dangerous” Category 4 storm with 145 mph sustained winds, now only about 70 miles west-southwest of Puerto Ángel, Mexico, heading for landfall.
This storm is expected to bring destructive winds, brutal rainfall (8–16 inches), mudslides, and severe coastal flooding across southern Mexico.


Sea Surface Temperatures: Atlantic Warming Continues

  • Gulf & Western Caribbean: SSTs remain warm at 84–88 °F, maintaining energy supply for potential tropical systems.

  • Main Development Region (MDR): Ocean temperatures are also above normal, setting the stage for Atlantic activity later in the season.
