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

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

Showers and thunderstorms associated with a non-tropical low 
pressure area centered about 300 miles northeast of Bermuda have 
diminished somewhat over the past several hours, and the system has 
not yet acquired subtropical storm characteristics.  However, 
the low is producing gale-force winds, and any increase in 
organization would result in advisories being initiated on the 
system later today or tonight as it moves westward to 
west-southwestward to the northeast of Bermuda.  Subsequently, 
the low is forecast to move northeastward into a more hostile 
environment by Saturday night or Sunday.  Additional information on 
this low pressure area can be found in High Seas forecasts issued by 
the NOAA Ocean Prediction Center and forecast products, including a 
tropical storm watch, issued by the Bermuda Weather Service.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.
