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.
