Atlantic Hurricane Outlook – August 5, 2025: Dexter Weakening, Two Other Areas Monitored
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.Saharan Air Layer (SAL):
A large SAL plume continues across the eastern and central Atlantic. Its dry, dusty air suppresses convection and hampers the vertical growth of tropical disturbances.Moisture:
While mid-level humidity is increasing over the western tropical Atlantic, SAL and shear are keeping much of the central MDR too dry for sustained thunderstorm development.
Gulf of America (Mexico) & Caribbean Overview
No disturbances are currently being monitored.
A stationary front and ridge of high pressure maintain light to moderate winds and calm seas across the Gulf and Caribbean.
Scattered showers remain typical for early August and are not linked to tropical systems.

Florida Forecast
Highs: Near 90 °F with high humidity.
Afternoon thunderstorms: 40–50% chance from sea breeze activity.
Winds: Light and variable inland, shifting southeast near the coast.
No tropical storm impacts are expected today.

Coleman Classic Cooler
Leak-resistant, insulated, and built to keep ice up to 5 days — available in multiple sizes for all your adventures.
Make sure your alert systems are working and up-to-date: test county-level emergency alerts, NOAA weather radios, and storm tracking apps. Confirm evacuation plans with household members and review where supplies are stored.
Outlook
Dexter poses no threat to land, but the tropical wave near Africa and Invest off the U.S. Southeast coast warrant close attention. August is historically when activity ramps up; conditions may become more favorable later in the week.
TL;DR – August 5 Snapshot
Tropical Storm Dexter weakening, drifting north but may reintensify offshore.
Two areas monitored: AL95 (30% chance) and African wave (~50% chance) for potential development.
SSTs remain warm, but SAL and wind shear continue to suppress many systems.
No tropical threats to Florida today—just typical summer storms.
Expect activity to increase as August progresses.
