Synopsis for Caribbean Sea and Tropical N Atlantic from

.SYNOPSIS...High pressure over the NW Atlantic will build while
it shifts SE to the central Atlantic waters. Fresh to strong
winds will pulse at night offshore Colombia through early next
week. Moderate to fresh NE to E winds are expected in the
Windward Passage and south of the Dominican Republic through the
weekend. 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 front. Fresh to strong N to
NE winds and 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.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front is analyzed from 31N33W to 24N45W, then
transitions to stationary from that point to 19N65W. Moderate to
fresh NE to E winds and rough seas to 9 ft are ongoing N of the
front between 55W and 62W. 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.
