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.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.

Prep Tip of the Day
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.

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.

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.

Florida Weather Outlook
Highs: Near 90 °F under sticky, humid conditions.
Conditions: Scattered afternoon thunderstorms from sea breeze interactions.
No tropical impacts expected today.

Prep Tip of the Day: Know Your Warning Signals
Test your alert systems today:
Confirm subscription to NOAA alerts and local county emergency systems.
Test NOAA weather radios and storm tracker apps.
Make sure household members know hurricane communication plans and locations of essential documents.
Outlooking Ahead
Invest Area AL95, while moving away from land, bears watching if it gains tropical characteristics. Meanwhile, the wave off Africa will pass into warmer waters—another early‑August indicator. 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.
