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

Active Systems:
The National Hurricane Center is issuing advisories on Tropical 
Storm Erin, located over the eastern tropical Atlantic several
hundred miles west of the Cabo Verde Islands.

1. Northwestern Atlantic:
A non-tropical area of low pressure located a few hundred miles 
southeast of Nova Scotia, Canada, is producing disorganized shower 
and thunderstorm activity to the west of its center.  Some 
limited tropical or subtropical development is possible over the 
next day or so as the low meanders near the relatively warm waters 
of the Gulf Stream.  The system is expected to move northward over 
cooler waters by Wednesday, ending its chances for tropical 
development.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.

2. North-Central Gulf:
A surface trough near the coast of Louisiana is producing a broad 
area of disorganized showers and thunderstorms.  While development 
of this system is not anticipated before it moves inland later 
today, locally heavy rainfall could produce flash flooding across 
portions of the northern Gulf coast over the next day or so.  For 
more information on the rainfall hazards related to this system, 
please see products issued by your local National Weather Service 
forecast office.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...near 0 percent.
