Individual waves may be more than twice the significant wave height. .SYNOPSIS...Showers and thunderstorms are beginning to show signs of organization with a broad low pressure centered over the NW Caribbean. Environmental conditions appear favorable for further development of this system, and a tropical depression or storm is likely to form over the next couple of days as the low moves north across the NW Caribbean and into the SE Gulf of Mexico, where additional development is possible. Regardless of development, heavy rain and increasing winds and seas are expected across portions of the eastern Gulf of Mexico by the middle of this week. There is a high chance of tropical formation within the next 48 hours. Gulf of Mexico N of 26N W of 87W .TODAY...E winds 10 kt. Seas 3 ft. .TONIGHT...E winds 10 kt.
