Atlantic Hurricane Outlook – July 14, 2025: Gulf Disturbance Signals Season’s Shift
A weak trough near Florida could organize as it moves into the Gulf of Mexico this week. While not yet a named system, heavy rain and flooding may impact Florida and Gulf Coast states. Stay informed and prepared.
The Atlantic basin remains mostly calm, but the tropics are waking up. A trough of low pressure is moving off the Southeast U.S. coast and entering the Gulf of Mexico, where it's now being monitored for potential tropical development later this week.
Atlantic Basin: Early Signs of Activity
No named tropical cyclones currently.
The trough is producing disorganized clouds and showers along the Southeast coast and across Florida.
According to the NHC, this system has about a 30% chance of organizing into a tropical depression or storm over the next seven days, with a 10% chance in 48 hours.
If it develops, it could move west across the Gulf toward Louisiana and Texas by late week.

Foundation: Ocean & Atmosphere Basics
Sea Surface Temperatures (SSTs) are 2–4°F above average in the Gulf, Caribbean, and Main Development Region—providing the warm fuel needed for development.

Wind shear remains moderate-to-strong across much of the basin; however, conditions in the northeastern Gulf may become more favorable for storm organization.
Saharan dust continues to suppress development in the eastern Atlantic, but this trough is well west of that region.

Local Weather: Rain and Thunderstorms Ahead
Florida: Expect multiple rounds of heavy rain and thunderstorms today through Wednesday as the trough crosses the peninsula.
Gulf Coast (AL, MS, LA, TX): Showers, thunderstorms, and flooding potential increase by mid-to-late week.
Attention zones: Tampa, Orlando, Dolphins could see over 6″ of rain; Houston and Mobile might experience heavy downpours and gusts.

Prep Tip: Heavy Rain Trumps Wind Now
With flooding as the primary threat:
Ensure your home’s drainage systems are clear.
Prepare sandbags and supplies if you live in low-lying or flood-prone zones.
Keep flashlight, battery-powered radio, and emergency kits on hand.
Continue monitoring NOAA Weather Radio and local alerts as storms advance.
Looking Ahead: Watch This Week Carefully
As the trough moves into the Gulf, developing into a tropical depression or storm is possible.
Even without full tropical development, heavy rain and localized flooding pose a risk to the Southeast U.S. and Gulf states.
This activity could become the season’s first system to affect U.S. mainland—track it closely over the next 3–7 days.

Atlantic Hurricane Outlook – June 4, 2025: A Flicker on the Horizon
Though no storms are active, key hurricane ingredients are aligning fast. A developing low near the Southeast U.S. and rising SSTs suggest change is coming.
The fourth day of the 2025 Atlantic hurricane season opens with quiet skies—but a subtle shift is underway. For the first time this season, the National Hurricane Center (NHC) has flagged a potential area of interest offshore the southeastern United States. While development chances remain low, it’s a reminder that conditions are evolving and the atmosphere is beginning to stir.
Atlantic Basin: A New Watch Zone Emerges
As of this morning’s Tropical Weather Outlook from the NHC:
No active tropical cyclones
One area of interest off the Southeastern U.S. coast
No tropical development expected in the next 48 hours
Low (10%) chance of development over the next 7 days
A non-tropical low pressure area is forecast to form near or offshore the Southeast U.S. coast.
If it remains offshore, it may gradually acquire subtropical or tropical characteristics while drifting northeastward at 10–15 mph.
— NHC Forecaster Reinhart, June 4, 2025
No storm is expected soon—but it’s the first official mention of potential development this season.

Sea Surface Temperatures: Ready for Action
Warm waters across the Atlantic basin continue to deepen—creating an ideal foundation for future storm formation:
Gulf of Mexico: Running 2–4°F above average, with pockets exceeding 86°F (30°C)
Western Caribbean: SSTs remain high, particularly around Central America and Cuba
Main Development Region (MDR): Trending warmer than normal with gradual warming expected into late June
This warm ocean water is the primary energy source for hurricanes—and it’s already in place.

Wind Shear & Moisture: Storm Barriers Continue to Erode
Atmospheric conditions are shifting in a storm-friendly direction:
Wind shear is weakening in key zones like the Gulf and Caribbean
Moisture levels are rising at both low and mid-levels of the atmosphere
Vertical instability is increasing, supporting larger, longer-lasting thunderstorms
This transition increases the likelihood that disorganized storms could become organized systems.

Saharan Air Layer: Still a Barrier, But Fading
A broad plume of Saharan dust remains in the central and eastern Atlantic, offering temporary protection:
Suppresses convection
Inhibits thunderstorm growth
Raises wind shear and dry air intrusion
However, models show this SAL influence weakening by mid-to-late June, removing one of the final natural inhibitors.

Thunderstorm Activity: Early Clues
Even in the absence of tropical storms, convective activity gives us clues about what's forming:
Western Caribbean & Bay of Campeche: Disorganized clusters of thunderstorms show signs of persistent convection
Southeastern U.S. Coast: Isolated convection associated with the developing non-tropical low
While nothing is organizing yet, this pattern often precedes early-season development.

Florida Forecast: Muggy Mornings, Stormy Afternoons
Expect typical summer conditions today across the state:
North Florida: Highs in the upper 80s, mostly sunny, low humidity
Central Florida: Around 90°F, with isolated thunderstorms after 2 PM
South Florida: Mid-80s, high humidity, with a greater risk of scattered PM storms
Afternoon thunderstorms are normal—but they also signal increasing moisture and instability across the region.

Prep Tip of the Day: Snap and Store
With one system on the radar, now’s a good time to check off a simple but essential task:
📸 Take photos of your home, car, and valuables
☁️ Back up those images to the cloud or email them to yourself
🔒 These photos may be critical for insurance documentation after a storm
Also:
Review your hurricane kit and evacuation plan
Sign up for emergency text alerts from local agencies
Bookmark trusted resources like Cat5Prep.com and hurricanes.gov
Looking Ahead: A Season Starting to Stir
It’s still early in the season, but we’re beginning to see motion on the map:
Warm water and shifting winds are laying the groundwork
The Saharan Air Layer is fading
Thunderstorm activity is creeping into critical regions
Today’s 10% chance of development is low—but it may mark the quiet season’s turning point.
We'll continue tracking changes in the Atlantic and bring you updated guidance each day.
