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.

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.

Florida Forecast
High temperatures: Near 90 °F under humid conditions.
Afternoon showers and thunderstorms: 40–50% likelihood due to sea breeze convergence.
Winds: Light and variable inland; east-southeasterly along the coast.
Precipitation: Not driven by tropical systems.

Take advantage of the lull to finalize your hurricane readiness:
Verify evacuation zones and travel routes.
Confirm alert registration with local and state emergency systems.
Update contact information and checklist locations with household members.
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 30, 2025: Development Chances Remain Low
As July ends, the Atlantic Basin sees active tropical waves, but development chances remain low for the next 7 days. Discover the latest on sea surface temperatures, wind shear, Saharan Air Layer, and the outlook from CAT5Prep.com.

** Due to technical issues on the GOES satellite imagery provider's end, we are currently unable to display real-time satellite imagery.
The Atlantic Basin remains active with multiple tropical waves stretching from the African coast to the Caribbean, yet no organized development is expected in the near term. Wind shear and Saharan dust continue to suppress cyclone formation despite warm ocean temperatures and a moistening atmosphere in the western basin.
As we close out July, conditions are slowly trending toward a more favorable setup for storm development heading into August.
Atlantic Basin Overview
As of the 8:00 AM EDT NHC Tropical Weather Outlook:
No active tropical cyclones.
Three tropical waves span the Atlantic:
Wave near 35°W (eastern Atlantic): Disorganized, little convection.
Wave near 50°W (central Atlantic): Producing scattered thunderstorms, no surface low.
Wave in the eastern Caribbean: Weak and encountering dry air and shear.
NHC Development Odds:
Next 48 hours: 0%
Next 7 days: 0%
Key Environmental Factors

Wind data at 850hPa from Windy.com
Sea Surface Temperatures (SSTs):
29–31°C (84–88°F) in the Gulf of Mexico and Caribbean.
MDR remains slightly warmer than normal.
Wind Shear:
Moderate across the central Atlantic and Caribbean.
Suppressing vertical development for now.
Saharan Air Layer (SAL):
Strong dry air across much of the basin.
Limiting convection and keeping tropical waves disorganized.
Moisture:
Gradually increasing in the western Atlantic and Caribbean.
A factor to monitor as wind shear begins to ease.
Gulf of Mexico (Gulf of America)
A weak surface trough in the central Gulf is producing scattered showers and isolated thunderstorms.
No signs of organization, and the NHC does not expect development at this time.
High pressure remains dominant elsewhere, with calm conditions expected through midweek.
Florida Weather
Highs in the upper 80s to low 90s with high humidity.
Scattered thunderstorms possible in the afternoon and evening from sea breeze interactions.
No tropical threats to Florida at this time.

The Atlantic remains broadly quiet for now, but the environment is slowly shifting. A steady wave train emerging off Africa and increasingly favorable SSTs point to a more active window in early to mid-August.
Now is the time to double-check hurricane kits, review evacuation zones, and prepare while the weather allows.
TL;DR – July 30 Snapshot
No tropical development expected this week.
Three tropical waves are present but remain weak and disorganized.
SAL and shear are limiting development.
Conditions should become more favorable by early August.
