Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Wed Oct 21 2026

For the North Atlantic...Caribbean Sea and the Gulf of America:

Offshore of the East Coast of the United States (AL93):
A storm-force non-tropical low pressure area located a few hundred 
miles off the mid-Atlantic United States coast is producing some 
shower and thunderstorm activity primarily west and northwest of its 
center. Over the next day or two, the low could gradually lose its 
frontal features while it moves slowly north-northeastward over the 
Gulf Stream, allowing the system to possibly develop subtropical 
characteristics. By Friday, the system is expected to accelerate 
northeastward away from the the eastern United States, and 
environmental conditions are expected to become unfavorable for 
additional subtropical or tropical development. 

Regardless of the status of the system, high winds, coastal 
flooding, and dangerous surf are expected along portions of the U.S. 
East Coast during the next few days. For more information, please 
consult statements and warnings from local National Weather Service 
offices and the Weather Prediction Center, along with the High Seas 
Forecasts and the Storm Warnings issued by the National Weather 
Service.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 7 days...medium...40 percent.
