For the North Atlantic...Caribbean Sea and the Gulf of America:
Off the East Coast of the United States:
A strong non-tropical low pressure area is expected to form during 
the next day or two off of the eastern coast of the United States. 
This low is likely to move slowly and erratically through the middle 
of next week, and some subtropical development is possible during 
this time. Regardless of whether subtropical development occurs, 
this system will cause high winds, coastal flooding, and dangerous 
surf along portions of the U.S. East Coast. Please consult 
statements and warnings from local National Weather Service offices 
and the Weather Prediction Center for more information, along with 
High Seas Forecasts issued by the National Weather Service.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...20 percent.
