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

A non-tropical low pressure system is expected to form off the east 
coast of the United States by tonight. The frontal low is forecast 
to move generally north-northeastward through early this week, and 
the system will likely bring rain and wind impacts to portions of 
the mid-Atlantic and northeast U.S. coast. The system should then 
begin to move eastward away from the U.S. coast by midweek. By the 
end of the week, the low could acquire some tropical or subtropical 
characteristics while it moves eastward or southeastward over the 
central Atlantic. For more information on this system, including 
storm watches and warnings, see products issued by your local 
National Weather Service office and High Seas Forecasts issued by 
the National Weather Service.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...40 percent.
