As of 27/0300 UTC a cold front extends across the basin from Jupiter Florida near 27N80W to Marco Island Florida near 26N82W to 23N90W to S of Veracruz Mexico near 19N96W. Radar imagery shows scattered showers over S Florida. Scattered moderate convection is noted over the Straits of Florida from 23N-25N between 78W-82W. Scattered showers are elsewhere within 60 nm of the front. Drier air prevails behind the cold front. Moderate to fresh winds are west of the front, with light to gentle winds east of the front. Seas are in the 4-6 ft range west of the front, and 1-3 ft east of the front. The cold front will move slowly SE across the eastern Gulf through tonight, then exit the area on Mon morning. Another cold front will move into the northern Gulf Wed afternoon, reach from the Florida Big Bend to near 25N90W and to near northeastern Mexico early Thu. The western part of the front will become stationary and weaken through late Thu night, while the rest of the front will weaken as it exits the SE Gulf Fri. Weak high pressure will build across the area in the wake of this front. CARIBBEAN SEA... A surface trough is over the Yucatan Peninsula from 21N89W to 16N90W.

Strong east to southeast winds will pulse tonight over the Gulf of Honduras. A weak cold front will sink across W Cuba and the Yucatan Channel Mon through Mon night before dissipating Tue. Northerly subsiding swell will propagate through the Tropical N Atlantic waters through Mon.
