Corrected to add mention of gale-force winds for the Atlantic low

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

Surface observations and recent satellite wind data indicate that a 
well-defined low pressure system over the western Gulf of Mexico has 
winds of 30-35 mph near and east of the center. The associated 
shower and thunderstorm activity remains limited, but any increase 
in this activity may result in the formation of a short-lived 
tropical depression or storm before the system moves inland over the 
northwestern Gulf coast tonight, and potential tropical cyclone 
advisories may be needed as early as this afternoon.  Regardless of 
development, the system could produce heavy rainfall over portions 
of southeastern Texas and southwestern Louisiana through Saturday.  
Given the complete saturation of soils with ongoing river flooding 
along the Texas and Louisiana coastal areas, heavy rain could lead 
to flash, urban, and additional riverine flooding across this 
region.  Additional information on the rainfall and flooding 
potential can be found in products issued by your local National 
Weather Service Forecast Office. 
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...medium...60 percent.
