...SMALL CRAFT SHOULD EXERCISE CAUTION...
Synopsis: Showers and thunderstorms will be on the increase through Sunday across the local waters. The strongest activity may locally increase winds and seas as well as produce cloud-to-water lightning. Additionally, pressure gradient will begin to tighten between a developing tropical system in the western Caribbean and a building surface high across the western Atlantic. This will likely cause elevated seas for the Atlantic. Gulf waters may also begin to become elevated as the tropical system is expected to move into the Gulf of Mexico by early next week generating at least a modest swell.

.GULF STREAM HAZARDS...Seas of 4 to 6 feet. Gusty winds and lightning possible.
