Synopsis for the the SW N Atlantic including the Bahamas
.SYNOPSIS...A surface trough extends from near 30N58W south-
southwestward to the Virgin Islands. A tight pressure gradient
between the northern portions of this trough and the subtropical
ridge to the north is leading to fresh to locally strong E winds
and rough seas N of 23N and E of 70W. Fresh NE winds will
continue on the NW side of the trough through Fri as the trough
remains nearly stationary. Winds should should diminish by the
weekend as the pressure gradient relaxes. Looking ahead, a cold
front may move southward, between Florida and 65W, late Sunday
into Monday followed by moderate to fresh N to NE winds.
