Atlantic Hurricane Outlook – June 5, 2025: A Weak Low, a Wet Southeast, and a Watchful Eye

June 5 brings continued calm in the Atlantic, with no named storms and no areas of concern. But warm sea surface temperatures and slowly shifting atmospheric conditions suggest more activity may be on the way later this month.

The fifth day of the 2025 Atlantic hurricane season begins with calm skies and no tropical activity on the horizon. While this early June quiet is typical, forecasters are closely watching for subtle atmospheric shifts that may usher in increased activity later in the month. Now is the perfect time to double-check your emergency plans while the weather remains cooperative.

Daily Hurricane Update for day of June 5, 2025

Sea Surface Temperatures: Warming Trend Continues

Ocean heat—an essential ingredient for tropical storm formation—is building across the Atlantic:

  • Gulf of America (Mexico): Widespread low to mid-80s°F (28–30°C), running above average

  • Western Caribbean: Seasonally warm, primed for potential development in coming weeks

  • Main Development Region (MDR): Temperatures are climbing faster than usual for early June, laying a foundation for future storms

Wind Shear & Moisture: Still Mixed, Slowly Improving

Atmospheric conditions aren’t yet fully supportive of tropical formation, but change is underway:

  • Wind Shear: Still moderate to high in the western Caribbean and central Atlantic—strong enough to disrupt organization. Long-range models show a gradual easing expected later in June

  • Moisture: Mid- and lower-atmosphere humidity is rising in the Gulf and Caribbean, hinting at increasing thunderstorm potential

Saharan Air Layer: Strong, But Temporary Barrier

The Saharan Air Layer (SAL) remains a major suppressing force across the tropical Atlantic:

  • Dry, dusty air and associated wind shear prevent tropical waves from organizing

  • This layer is expected to weaken by mid-to-late June, removing a key obstacle to development

Thunderstorm Activity: Typical Early Summer Patterns

No tropical cyclones—but thunderstorm activity continues in familiar places:

  • Florida: Scattered afternoon storms expected from daytime heating

  • Western Caribbean: Some disorganized convection is present but lacks structure

  • Off the U.S. East Coast: No significant organized convection at this time

Florida Forecast – Early Summer Vibes Across the Peninsula

Expect a classic early summer day throughout Florida:

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

  • Humidity: Elevated levels bringing a muggy, tropical feel all day

  • Rain: Scattered afternoon thunderstorms likely, mostly brief and localized

  • Winds: Light and variable, with gentle breezes in many areas

Stay hydrated and be prepared for brief showers if you’re out and about this afternoon!

Atlantic Hurricane Outlook – June 3, 2025: Conditions Ripening Beneath the Calm

The 2025 Atlantic hurricane season starts quietly, but today, June 3, 2025, the National Hurricane Center identifies a new low-pressure area off the Southeastern U.S. coast. Conditions are slowly becoming more favorable for storm development this week.

The third day of the 2025 Atlantic hurricane season begins much like the last—quiet skies and no named systems. But meteorologists are watching closely. While there are no storms on the map, the ingredients for tropical cyclone formation are slowly assembling. Sea surface temperatures are rising, atmospheric inhibitors are weakening, and thunderstorm activity is beginning to build in key regions. It’s still early—but don’t get too comfortable.

Atlantic Basin: New Area of Interest and Overall Quiet

As of yesterday afternoon’s update from the National Hurricane Center (NHC), a new area of low pressure has been identified just off the southeastern United States coast:

  • A non-tropical area of low pressure is expected to form near or offshore of the southeastern U.S. coast in the next couple of days.

  • If it remains offshore, it could gradually acquire subtropical or tropical characteristics later this week while tracking northeastward at 10 to 15 mph.

  • Formation chance through 48 hours: Low (near 0%)

  • Formation chance through 7 days: Low (10%)

While development is currently unlikely, this is the first flagged area of interest in the Atlantic this season — a reminder that conditions are slowly trending more favorable. Models will continue to be monitored for any shifts in track or intensity.

At this time, no direct impacts are expected for the U.S. mainland, but boaters and beachgoers along the Southeast Coast should monitor local marine conditions later this week.

Otherwise, the basin remains quiet:

  • No active tropical cyclones

  • No other areas of interest

  • No tropical development expected in the next 7 days

A quiet start like this is typical for early June but it’s not a signal to let your guard down. The long-range outlook hints at increasing activity potential by mid-to-late June, especially in the western Caribbean and Gulf of America (Mexico).

Sea Surface Temperatures: Storm Fuel Is Already in Place

Warm waters are the engine that powers hurricanes, and the Atlantic is already running hot:

  • Gulf of America (Mexico): 2–4°F above average, with widespread 86°F+ (30°C) readings

  • Western Caribbean: Elevated SSTs continue to build near Central America and Cuba

  • Main Development Region (MDR): Trending warmer than normal, with the potential to support long-track storms later this season

These above-average temperatures are primed to support rapid intensification once storm systems begin to form.

Wind Shear & Moisture: A Shifting Balance

Wind shear—the atmospheric force that disrupts hurricane development—is weakening, especially in the Caribbean and Gulf. At the same time, moisture levels in the lower and mid-atmosphere are rising.

This combination supports stronger thunderstorms and vertical cloud development—key precursors for tropical formation.

Saharan Air Layer: Dust Is Holding Steady—for Now

A broad stretch of the Saharan Air Layer (SAL) is still active across the central and eastern Atlantic:

  • Dry, stable air disrupts tropical wave development

  • Increased wind shear limits vertical convection

  • Dust particles reduce storm cloud organization

While the SAL continues to offer some protection in the eastern Atlantic, it’s expected to weaken later this month—removing one of the last early-season barriers to storm growth.

Thunderstorm Activity: Not Just Summer Weather

While today’s thunderstorms aren’t tropical, their growing presence is important:

  • Western Caribbean: Clusters of convection are forming, though currently disorganized

  • Southeastern U.S. & Gulf Coast: Expect afternoon storms, fueled by heat and humidity

These storm systems help prime the atmosphere for eventual tropical development and are often the earliest signs of areas of interest.

Florida Forecast: A Classic, Stormy Summer Day

Expect another typical early June day across the Sunshine State:

  • North Florida: Upper 80s, low humidity, mostly clear

  • Central Florida: Around 90°F with building humidity and scattered PM storms

  • South Florida: Mid-80s, muggy, with increased chances of storms after 2 PM

Though today’s storms are not tropical, the overall pattern is signaling a slow seasonal transition.
