Marine weather discussion for Gulf of Mexico...Caribbean Sea and southwest north Atlc S of 31n

Tropical Storm Ida is about to make landfall and was located near 29.5n 88.8w at 0600 UTC. The forecast calls for Ida to become extratropical later this morning as it moves inland. As Ida moves inland strong nly winds behind a frontal boundary will affect the Gulf. The front will extend from the Florida Big Bend to the western tip of Cuba tonight and move E of the area Wed afternoon. The winds will decrease from W to E and the strongest wind will be confined to the E Gulf Thu and becoming light on Fri. Sly return flow will increase to 15 kt over the western Gulf...W of around 95w Sat. Otherwise light winds over the remainder of the Gulf.

Strong high pres in the Atlc N of the area will continue to produce a strong pres gradient across the Atlc zone today. As a result NE-E winds 20-25 kt will continue across most of the area. The high shifts further to the E on Wed while the remnants of Tropical Storm Ida gets absorbed by a cold front. This will loosen the pres gradient across much of the area except for the far NW portion of the zone where sly winds will increase ahead of the front. The front will move off the se U.S. Coast Wed night and extend from 31n77w to W Cuba Thu and from 31n75w to central Cuba Fri and from 31n70w to E Cuba. Winds will be 20-25 kt both ahead and behind the front Thu and Fri then decrease Sat as the front weakens.

Weak pres gradient will remain across most of the Caribbean with light to moderate trades continuing through Fri. A cold front will move into the NW Caribbean Wed night into Thu and will stall and dissipate in the western Caribbean Fri. W to NW winds behind the front will briefly increase to 20-25 kt.
