Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Tue Oct 20 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 of its center.
Satellite imagery indicates that the low is still frontal. Over
the next couple of days, the low could gradually lose its frontal
features while it moves slowly north-northeastward over the
Gulf Stream, allowing the system to briefly develop subtropical
characteristics. By the end of the week, 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.
