Marine weather discussion for the Gulf of Mexico, Caribbean Sea, and tropical North Atlantic from 07n to 19n between 55w and 64w and the southwest North Atlantic including the Bahamas

...Gulf of Mexico...

An upper-level low is centered over the N Yucatan Peninsula near 22n89w. Scattered showers prevail over the Yucatan Peninsula and the se Gulf of Mexico S of 25n and E of 90w. A large upper-level high is centered over N Mexico near 24n106w. Northerly upper- level flow is over the W Gulf.

A stationary front extends from E Texas near 30n93w to 25n94w. Scattered moderate convection is within 90 nm of the front. Expect the front to dissipate tonight. Light to gentle winds will generally prevail the next couple of days before increasing slightly during the second half of this week. Seas of 3 ft or less are expected. A surface trough will develop over the Yucatan Peninsula each evening, shift W over the SW Gulf each night, then dissipate each morning. Moderate to fresh winds will accompany the trough.

...Caribbean Sea and tropical N Atlantic from 07n to 19n between 55w and 64w...

The eastern Pacific monsoon trough combined with diffluence aloft continues to enhance scattered moderate to strong convection over the SW Caribbean S of 12n between 78w-84w. Elsewhere, scattered showers are over the NW Caribbean W of 80w.

Remnants of Kirk were near 10.0n 39.5w 1007 mb at 11 am EDT moving W at 20 kt. Maximum sustained winds 35 kt gusts 45 kt. Kirk is now an open tropical wave. Gale-force winds are expected to continue along the northern portion of the wave for the next few days as it continues to move westward. Otherwise, fresh to strong winds will prevail over the central Caribbean through midweek.

...SW N Atlantic including the Bahamas...

A broad 1012 mb low is centered NE of the Bahamas near 29n73w. A surface trough extends S from the low center to 25n75w. Scattered moderate to isolated strong convection is from 27n-34n between 68w-75w. Environmental conditions are forecast to become slightly more conducive for development during the next day or so while the system moves west-northwestward to northwestward. By Tue night and Wed, upper-level winds are expected to increase, limiting the chances for additional development, while the system moves northward near the southeastern United States coast. High pres will build north of 30n in the wake of this low. Long period swell caused by subtropical storm Leslie and a northern Atlantic cold front will cause seas to build E of 70w starting Wed.

Fresh to strong easterly winds will pulse along the northern coast of Hispaniola the next two afternoons.
