Strong high pressure over the Ohio Valley is supporting strong N to NE winds over the SE half of the Gulf behind a slow moving cold front in the NW Caribbean. Winds and seas will gradually diminish today as the high shifts northeastward. Strong NE to E winds will continue across the E Gulf and through the Straits of Florida through Fri night as the cold front stalls. A N to S aligned surface trough will develop across the central Gulf Fri, with strong E winds covering the Gulf E of trough. Low pressure is expected to develop from the trough over NE Gulf by early Sat and move across northern Florida this weekend. Gale force winds are possible in the NE Gulf late Sat through Sat night. EC and UKMET solutions very silmilar for this event and have trended strongly with EC guidance. NE Gulf coastal offices encouraged to be more aggressive with wind and sea forecasts for this event. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W...
