TL;DR – August 7 Snapshot
Tropical Storm Dexter is becoming extratropical and poses no land threat.
Invest 96L carries a 60% chance of development this week.
Another disturbance offshore the Southeast U.S. has 30–40% development odds but remains away from land.
Warm ocean temperatures and easing shear are creating a more favorable environment.
The active season is ramping up—stay prepared and stay tuned.
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.
Gulf & Caribbean Update
No disturbances in the Gulf or Caribbean seas.
High-pressure dominance maintains generally dry conditions, with scattered showers typical of early August.
Expect stable marine conditions without organized tropical activity.

Atlantic Hurricane Outlook – June 1, 2025: Opening Day, But All’s Quiet… For Now
June 1 marks the official start of the 2025 Atlantic hurricane season. No storms are currently active, but rising sea surface temperatures and favorable patterns suggest a potentially busy season ahead.
The Atlantic hurricane season officially begins today, June 1, and while the tropics are currently quiet, forecasters are already eyeing the environmental conditions that could lead to a very active season. For residents in hurricane-prone regions, now is the time to prepare—not relax.
Atlantic Basin: Calm Start to the Season
As of the latest update from the National Hurricane Center (NHC), there are no active tropical systems, no areas of concern, and no immediate threats expected over the next seven days.
This quiet opening is not unusual. Early June often sees little activity in the deep tropics. However, this calm is not expected to last. Sea surface temperatures are running well above average, and the atmospheric setup is trending toward conditions favorable for development later this month.

Sea Surface Temperatures: Running Hot
The Atlantic basin is notably warm for this early in the season, providing more than enough fuel for potential tropical cyclones.
Gulf of America (Mexico): 2 to 4°F above normal, with widespread areas exceeding 86°F (30°C)
Caribbean Sea: Similar temperature anomalies, especially in the western basin
Main Development Region: Continues trending above average
Historically, warmer-than-average waters correlate with more frequent and intense storms.

ENSO Neutral: La Nada Takes Over
The El Niño–Southern Oscillation (ENSO) is now in a neutral phase. With El Niño in the rearview and La Niña not yet in play, we enter what meteorologists call "La Nada"—a neutral state that often removes inhibiting influences on hurricane formation.
Decreased wind shear is expected across the Atlantic basin
A neutral ENSO often correlates with average to above-average storm development
Other patterns, like the Madden–Julian Oscillation (MJO), may become more influential later in the month
Saharan Air Layer: Dust Still in Play
The Saharan Air Layer (SAL) continues to stream across the Atlantic from Africa, bringing with it dry, dusty air that temporarily suppresses tropical development.
Inhibits cloud formation and convection
Increases atmospheric stability
Introduces vertical wind shear
The SAL typically begins to weaken later in June, removing one of the key atmospheric barriers to tropical development.

Eastern Pacific: Alvin Weakens
Tropical Storm Alvin, the Eastern Pacific's first named storm of the season, formed earlier this week and is now weakening.
Location: Approximately 710 miles south of Baja California
Movement: Northwest at 13 mph
Maximum Winds: 50 mph, weakening
Forecast: Expected to dissipate within 36 hours
Though Alvin poses no threat to land, its formation signals that tropical systems are beginning to stir in the broader region.

Florida Forecast: Statewide Conditions Typical for June
Across the state of Florida, today's weather reflects classic early summer patterns.
North Florida: Highs in the upper 80s, lows in the mid-60s, low humidity, mostly clear skies
Central Florida: Highs near 90°F, afternoon humidity and a slight chance of thunderstorms
South Florida: Highs in the mid-80s, lows in the upper 70s, muggy with isolated afternoon storms
These are the kinds of conditions that typically precede the onset of more frequent tropical activity in late June and July.
