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 
north-northeastward 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 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.
