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

A non-tropical low pressure system located about 230 miles south-
southeast of the South Carolina-North Carolina border has moved
little during the past several hours.

Since yesterday, the low has
become better defined with increasing organization of the associated
thunderstorm activity.  

Environmental conditions are gradually
becoming more conducive for development, and an increase in the
organization of the thunderstorms could result in the formation of a
subtropical cyclone later today or on Friday.  An Air Force Reserve
reconnaissance aircraft is scheduled to investigate the low this
morning.  The low is expected to drift generally northward over the
next couple of days, and interests along the southeastern coast of
the United States should continue to monitor the progress of this
system. Regardless of development, heavy rain is expected over
portions of the coastal southeastern United States for the next
several days. For additional information, see products from your
local National Weather Service forecast office and High Seas
Forecasts issued by the National Weather Service. The next Special
Tropical Weather Outlook on this system will be issued by 2 PM EDT.
* Formation chance through 48 hours...high...70 percent
* Formation chance through 5 days...high...70 percent
