For the North Atlantic...Caribbean Sea and the Gulf of America:
Off the East Coast of the United States:
A storm-force non-tropical low pressure area is located along a 
frontal boundary a few hundred miles off the southeast coast of the 
United States. This low is likely to move slowly and erratically 
over the next couple of days. If the low remains over the Gulf 
Stream and becomes detached from the front, it could briefly acquire 
some subtropical cyclone characteristics during the middle to latter 
portions of the week. The system is expected to begin to move 
northeastward away from the the eastern United States later this 
week, and environmental conditions are expected to become 
unfavorable for development by the weekend.  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. Please consult statements and warnings from local 
National Weather Service offices and the Weather Prediction Center 
for more information, along with High Seas Forecasts and Storm 
Warnings issued by the National Weather Service.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...40 percent.
