Atlantic Hurricane Outlook – July 23, 2025: Gulf Disturbance Brings Rain Risk, Tropics Mostly Stable

A low-pressure system in the north-central Gulf is bringing rain to Florida and the northern coast, but development remains unlikely. Multiple waves in the Atlantic are being monitored.

The Atlantic basin remains quiet overall, but a new area of interest has developed in the north-central Gulf of Mexico, with a low (10%) chance of tropical development. Elsewhere, multiple tropical waves continue their westward journey across the Atlantic, but none show signs of immediate organization.

Gulf of Mexico: Watching a Coastal Disturbance

As of the 8:00 AM EDT update from the National Hurricane Center, a trough of low pressure just offshore the southeastern United States is producing disorganized showers and thunderstorms over the north-central Gulf. The system is forecast to drift west-southwestward over the next day or two into more open waters.

  • Chance of development remains low (10%) as the system will likely move inland before organizing.

  • Regardless of development, locally heavy rain is expected along the Florida west coast and the northern Gulf coast through the weekend.

We'll continue to monitor this system closely for any signs of improvement in structure.

Atlantic Basin: Multiple Waves Being Tracked

There are no active tropical cyclones, but several waves are being tracked in the deep tropics:

  • A tropical wave near 40°W continues to produce scattered convection but remains disorganized.

  • A new wave near 23°W just off the African coast was introduced in this morning’s outlook. It’s producing moderate convection along its southern extent.

  • A low-pressure feature near 08N44W, embedded within the monsoon trough, is also aiding convection but not expected to develop in the near term.

These features will be watched for signs of improved structure as they move westward.

Caribbean & Western Atlantic: Typical July Conditions

  • Scattered thunderstorms continue near eastern Cuba, Hispaniola, and the southwest Caribbean.

  • Trade winds remain moderate to fresh across much of the basin.

  • Seas range from 4 to 8 feet, highest in the south-central Caribbean.

  • The Saharan Air Layer remains weak to moderate, allowing more moisture into the mid-tropics.

Florida Forecast

  • Highs: 89–92°F (32–33°C)

  • Humidity: High, with heat index values over 100°F possible

  • Rain chances: Elevated this afternoon due to outer moisture from the Gulf disturbance

  • Winds: Light east-southeast, higher near thunderstorms

Prep Tip of the Day: Don’t Let “Low Chances” Lull You

Even disturbances with low formation chances can bring:

  • Flash flooding

  • Power outages

  • Road hazards

Use today to test emergency alerts, stock up on essentials, and make sure you’re signed up with your county’s emergency management system.

Looking Ahead

While July continues to show gradual tropical stirring, the big-picture signals—warmer SSTs, decreasing shear, and more active wave patterns—still point toward a ramp-up in early August. Stay ahead of it, and keep checking back for the latest updates.

Atlantic Hurricane Outlook – July 9, 2025: Calm Seas Persist Amid Seasonal Build

The Atlantic remains quiet today, with no active storms and no development expected. But record-warm waters and shifting atmospheric patterns suggest that tropical activity could ramp up soon.

Mid-July typically signals more tropical activity—but today, the Atlantic remains unusually quiet. According to the latest NHC updates, no tropical cyclones are present, with no expected development over the next seven days. Despite the current calm, strong indicators suggest the season’s intensity is primed to rise.

NOAA NHC Daily Hurricane Update - July 9, 2025

Atlantic Basin: All Clear for Now

  • No active systems in the Atlantic, Caribbean, or Gulf

  • NHC forecast maintains zero development chances across the basin

  • This lull is rare for July and may end soon as heat and moisture build

Seasonal Outlook: Above-Normal Conditions Ahead

  • CSU’s July update continues to forecast an above-average season:
    ~17 named storms, including ~9 hurricanes and ~4 major hurricanes .

  • NOAA similarly predicts 13–19 named storms, with a 60% chance of a busier-than-average season.

Sea Surface Temperatures: High Heat Levels

  • Atlantic SSTs remain well above normal—2–4°F above average—in the Gulf, Caribbean, and MDR

  • These elevated temperatures continue to provide plenty of energy for storm formation in the weeks ahead

Atmospheric Conditions: Secondary Barriers Easing

Wind Shear Courtesy of https://tropic.ssec.wisc.edu/

  • Wind shear remains moderate-to-high, particularly in the eastern Atlantic—temporarily limiting development

  • Saharan Air Layer (SAL) and occasional dry mid-level air still suppress convection but are expected to diminish

  • Moisture is steadily increasing, with abundant humidity projected across storm-prone regions

What to Watch Next

  • Upcoming Infrared and visible satellite loops for signs of organization

  • Shifts in wind shear over the Gulf and Caribbean

  • Any African easterly waves gaining moisture and structure

Early July Trends

  • Only one named storm (Chantal) has formed so far, but it remained weak and quickly dissipated 

  • History shows many July systems originate in the Gulf, Caribbean, or off the Southeast U.S. coast

Outlook: Active Patterns Brewing

  • While quiet now, the combination of warm SSTs, moist air, and weakening shear/SAL signals a rising likelihood of Atlantic development

  • Hurricane Season Peak is still ahead—August through October—but increased vigilance is essential now

Prep Tip of the Day: Check Your Alert Systems

With the season expected to intensify:

  • Confirm NOAA Weather Radio is operational

  • Enable emergency alerts on all devices

  • Update your hurricane kit and evacuation plan

  • Bookmark Cat5Prep.com and the National Hurricane Center for future updates

The Atlantic remains calm—but the foundation for tropical activity is strengthening daily. Stay alert, stay prepared, and check back tomorrow for your next Cat5Prep.com outlook.
