Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...1027 mb high pressure centered just NE of the area and the associated subtropical ridge extend to the Straits of Florida. The high will weaken through Mon as a cold front moves into the western Atlantic, with reinforcing high pressure building behind it, and due north of the Caribbean basin. This pattern will sustain fresh to strong easterly trades across most of the basin through Wed, including the Windward Passage. Winds will pulse nightly to gale force off the coast of Colombia through Mon night, however strong to near gale force winds will continue through the remainder forecast period. High seas in mixed N and NE swell across the tropical Atlantic waters will subside Mon night. Strong trade winds prevailing east of the Leeward Islands will diminish to fresh speeds Sun night.

A cold front extends across the Atlantic from 31N71W to the extreme south Florida and is moving SE. Fresh to strong trade winds will prevail S of 22N through early Mon as the high drifts NE and weakens. The pressure gradient between the ridge and the front will support strong SW winds ahead of the frontal boundary, N of 29N through today as the frontal boundary continues southeastward. Strong northerly winds will prevail behind the front through this morning then winds will begin to veer and gradually diminish as the front reaches from 31N57W to the NW Bahamas Sun morning, and then stalls. Weak high pressure will then prevail through early next week. ATLC waters from 27N to 31N W of 77W .TODAY...NE winds 10 to 20 kt. Seas 6 to 9 ft. .TONIGHT...E winds 10 to 20 kt.
