Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N W of 55W .SYNOPSIS...High pressure over the NW Atlantic will build while it shifts SE to the central Atlantic waters.

Moderate to fresh NE to E winds are also expected in the Windward Passage and south of the Dominican Republic Sat through Sun. Fresh SE winds in the Gulf of Honduras will reach strong speeds tonight and expand to the remaining NW Caribbean W of 82W ahead of a cold front forecast to move across the Yucatan Channel into the NW basin Mon morning. Rough seas are expected with the strong winds preceding the arrival of the front. Fresh to locally strong N to NE winds and mainly moderate seas will be associated with the passage of the front, which is forecast to reach from eastern Cuba to NE Honduras by Tue morning, from the Windward Passage to NE Nicaragua Tue evening before dissipating late Wed.

Moderate to fresh NE to E winds and rough seas to 9 ft are ongoing N of the front between 55W and 65W. The tail end of the front will lift N through the weekend while weakening. High pressure over the NW Atlantic will build while it shifts SE to the central Atlantic waters through early next week. The pressure gradient between the associated ridge and the remnants of the aforementioned front will lead to the development of fresh to strong winds north of 22N and E of the Bahamas this weekend. These winds will support building rough seas across E of the Bahamas. Looking ahead, a strong cold front will push off the SE United States coast early Mon preceded and followed by fresh to near gale force winds. The front will reach from 31N68W to the Turks and Caicos and eastern Cuba Tue morning, and from Bermuda to Puerto Rico Wed morning.
