For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

A deep, non-tropical low pressure system with storm-force winds is 
located less than 100 miles east-southeast of Cape Cod, 
Massachusetts.  The extratropical low is expected to meander off of 
the mid-Atlantic and northeastern U.S. coasts today, bringing rain 
and wind impacts to portions of those areas.  Thereafter, the low is 
expected to move eastward away from the United States, and it could 
acquire some subtropical characteristics while it moves eastward or 
southeastward over the warmer waters of the central Atlantic through 
this weekend.  For more information on this system, including storm 
warnings, see products issued by your local National Weather Service 
office and High Seas Forecasts issued by the National Weather 
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...medium...40 percent.
