Atlantic Hurricane Outlook – July 31, 2025: Tropics Active But No Storms on the Horizon
Tropical waves continue to move across the Atlantic, but none show signs of organization. Saharan dust and wind shear are keeping storm development in check—for now.
*Those who like data, continue reading. Those it prefer the quick version, jump to the TL;DR here.
The Atlantic basin continues to host several tropical waves—but none are expected to organize into tropical cyclones over the next seven days. Despite warm seas and increasing moisture, wind shear and Saharan dry air maintain a suppressive environment.
Atlantic Basin Summary
As of the 8:00 AM EDT Tropical Weather Outlook (TWO) from the National Hurricane Center, there are:
No active tropical cyclones.
No areas under investigation for development in the next 48 hours or seven days.
The Tropical Weather Discussion (issued at ~12:15 UTC) reveals:
A tropical wave near 43°W (south of 22°N) moving westward at 10–15 kt, with scattered moderate convection between 4–10°N.
Another wave near 55°W (south of 18°N) moving west at about 10 kt, with minimal convection.
These waves are being monitored but show no organized structure or circulation at present.
Key Weather Factors
Sea Surface Temperatures (SSTs):
Across the Gulf of Mexico, Caribbean, and MDR, SSTs range from 29–31 °C (84–88 °F)—values supportive of tropical development if atmospheric conditions improve.
Wind Shear:
Remains moderate to high across most of the Atlantic basin, limiting vertical development of disturbances.
Saharan Air Layer (SAL):
Dry and dusty air persists across the central and eastern Atlantic, suppressing convection in the MDR.
Atmospheric Moisture:
While moisture is gradually increasing near the Caribbean and western tropical Atlantic, the dry air and shear continue to hinder system organization.
Gulf of America (Mexico) & Caribbean Region
No low-pressure areas or disturbances are being tracked.
A dominating high-pressure ridge supports generally light winds and calm seas across the Gulf and Caribbean.
Offshore rainfall remains typical for this time of year—no tropical impacts on the Florida peninsula.

Outlook & Future Signal
Although today’s conditions remain tranquil, the ongoing wave train emerging from Africa and gradually improving moisture and SST profiles suggest that rainfall and organization potential may increase in early August.
TL;DR – July 31, 2025 Snapshot
No tropical systems present.
Two tropical waves travel west, but show none of the structure needed for development.
Strong wind shear and Saharan dust continue to suppress storm formation.
Warm waters and increased moisture hint at higher activity potential in August.

Atlantic Hurricane Outlook – July 19, 2025: Disturbance in the Deep Tropics Eyes Development
A tropical wave southwest of the Cabo Verde Islands shows a low chance of development as it moves westward. Conditions remain mixed across the Atlantic, but signs of activity are increasing.
The Atlantic Basin remains relatively quiet today, but there’s a new player on the map. A tropical wave in the central tropical Atlantic—labeled Disturbance 1—has a low but notable chance of development over the next week. This marks the first sign of deeper tropical activity emerging from the Main Development Region (MDR) as we move closer to peak hurricane season.
Atlantic Basin Overview: One Area to Watch
As of 8:00 AM EDT Saturday, July 19, 2025, the National Hurricane Center is monitoring:
No named tropical cyclones
One disturbance in the central Atlantic
Tropical development chances:
10% over 48 hours
20% over 7 days
Disturbance 1 is a tropical wave located about 900 miles west-southwest of the Cabo Verde Islands, interacting with a broad area of low pressure. Showers and thunderstorms remain disorganized, but marginally favorable conditions could support slow development as the system moves west to west-northwest around 10 mph.
However, by mid-week, environmental conditions are expected to become less favorable, limiting its window for intensification.

Sea Surface Temperatures: Fuel in Place
Waters remain very warm across much of the Atlantic:
Gulf of Mexico: Holding above 86°F (30°C) in many areas
Western Caribbean: High SSTs remain steady
Main Development Region (MDR): Warm enough to support tropical wave development—an important factor as more systems emerge off Africa
These warm waters are key to supporting systems like Disturbance 1.
Sea Surface Temperature data courtesy of Windy.com
Wind Shear & Moisture: Still Mixed
Wind Shear: Moderate in the eastern Atlantic near Disturbance 1 but lower closer to the Caribbean
Moisture: Rising across the western Atlantic, but dry air from the Saharan Air Layer (SAL) is still suppressing deeper convection across much of the MDR
While the disturbance has some support for development, these mixed upper-atmospheric conditions could limit growth.

Relative Humidity (ECMWF) data courtesy of Windy.com
Saharan Air Layer: Still an Inhibitor
Dry, dusty air continues to stretch across much of the central and eastern Atlantic. It:
Reduces storm cloud organization
Increases atmospheric stability
Weakens convection associated with tropical waves
SAL is expected to persist into early August but may begin to recede gradually.

Prep Tip of the Day: Know the Early Signs
With deeper Atlantic activity beginning, now is a good time to refresh your awareness:
Follow NHC's five-day outlooks
Understand what “low chance” really means—it can change fast with heat and time
Review your emergency communication plan and make sure alerts are enabled
Looking Ahead: Watch the MDR
While Disturbance 1 may or may not develop, its emergence from the Cabo Verde region is a signal that the deep tropics are beginning to stir. Expect more waves in the coming weeks as we approach the climatological ramp-up of hurricane season.

Prep Tip of the Day: Be Rainwise
Even without strong winds, heavy rainfall can pose serious hazards:
Track the trough’s movement—it could bring localized flash flooding to Gulf coast areas.
Ensure storm drains and sump pumps are clear and functional.
Keep sandbags and quick barriers ready if you're in low-lying zones.
Test your NOAA Weather Radio and mobile alerts to stay ahead of rainfall warnings.
Looking Ahead: Waters Stay Warm—Storms Could Spark
Although the tropics are peaceful now, the combination of warm ocean temperatures, easing atmospheric inhibitors, and growing seasonal moisture suggest readiness for evolution. The trough may serve as the first spark of Gulf activity, with a watchful eye needed through mid- to late-week.
