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 – June 6, 2025: Quiet Tropics, No Development Expected

June 6, 2025: No named storms or tropical threats in the Atlantic basin today, but signs of change are emerging. Sea surface temperatures continue to climb, and wind shear may weaken in the coming weeks. Now’s the time to review your hurricane prep plan.

The 2025 Atlantic hurricane season continues with a calm week, as no tropical cyclones or areas of concern are present. The National Hurricane Center (NHC) confirms no tropical development is expected over the next seven days, marking a quiet yet cautious start to June.

Daily Hurricane Update 6-6-25

Atlantic Basin: Clear Skies for Now

From the 8 AM EDT Tropical Weather Outlook issued June 6:

  • No active tropical cyclones

  • No areas of concern

  • No development expected in the next seven days

The NHC’s maps and guidance reflect this assessment, indicating a continued quiet period. Notably, previous offshore coastal disturbances have been dropped and are no longer being tracked.

Sea Surface Temperatures: Stable But Still Warm

Warm SSTs persist in regions key to hurricane development:

  • Gulf of America (Mexico) & Western Caribbean: Remain seasonally warm (low to mid-80s°F)

  • Main Development Region (MDR): Still trending above normal for early June

While SSTs provide essential fuel, other atmospheric factors currently suppress development.

Wind Shear & Moisture: Conditions Not Yet Favorable

  • Wind Shear: Moderate across much of the basin, particularly in the western Caribbean and central Atlantic

  • Atmospheric Moisture: Rising gradually, but not yet supportive of storm formation

These conditions reduce the likelihood of tropical development in the immediate future.

Saharan Air Layer: Suppression in Full Effect

A strong plume of Saharan dust continues to suppress Atlantic convection:

  • Dry air and elevated shear persist across the eastern tropical Atlantic and MDR apnews.com

  • The SAL remains a key barrier to any early-season system development

  • Expect this barrier to weaken later in June

Thunderstorm Activity: Localized, Non-Tropical

  • Florida & Southeastern U.S.: Scattered afternoon thunderstorms—normal for this season

  • Western Caribbean: Isolated, disorganized showers and storms with no rotation

  • Eastern U.S. Coast: No significant organized convection detected

These are routine summer thunderstorms—not tropical systems.

Florida Forecast: Typical Early Summer Conditions

Expect another classic June day:

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

  • Humidity: Moderate to high, creating muggy conditions

  • Rain: Scattered afternoon and evening showers likely

  • Winds: Light and variable

Prep Tip of the Day: Emergency Alerts and Insurance

Take advantage of today’s calm to:

  • Confirm your emergency alert subscriptions, including text and email

  • Review your insurance coverage and update policy details if needed

  • Gather digital and physical copies of critical documents

  • Familiarize yourself with evacuation zones in your area

Looking Ahead: Still Calm, But Stay Vigilant

NHC projections show no tropical development through June 13–14, but underlying conditions—particularly warm waters and gradually weakening shear—will become increasingly favorable. The primary barriers are the Saharan dust layer and fluctuating atmospheric moisture.

Remember: hurricanes can form quickly when conditions align. Continue to monitor daily forecasts at Cat5Prep.com.
