Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N W of 55W

.SYNOPSIS...A weak ridge will continue N of the area along 29N
and E of 75W into Tue. Fresh to strong trades and rough seas
over the south-central Caribbean will expand across most of the
central portions of the basin Wed through Fri night as Atlantic
high pressure gradually builds westward across Florida and into
the eastern Gulf of America. Fresh E winds are expected in the
Gulf of Honduras tonight and again Wed night through Sat.
Moderate to fresh winds and moderate seas are expected in the
eastern Caribbean through the period while gentle to moderate
winds and slight to moderate seas will prevail in the NW
portions. A pair of tropical waves will move through the basin
tonight through Fri, mainly producing active weather across the
SW Caribbean waters.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A weak ridge along 29N will continue E of 75W
tonight into Tue. Elongated low pressure extending from offshore
the southeastern U.S. coast to offshore of central Florida is
expected to move westward across Florida Tue through Tue night,
and eventually emerge over the northeastern Gulf of America by
early Wed. Environmental conditions appear favorable and some
gradual development of this system is possible while it moves
westward to west-northwestward across the northeastern and north-
central portions of the Gulf during the middle to latter part of
this week. High pressure over the central Atlantic will then
build westward across the region and into Florida Tue night
through Sat in the wake of the low pressure. Active thunderstorms
are expected in association with this system over the waters
west of 75W through Tue evening. The pressure gradient between
the Atlantic ridge building westward and the low pressure will
support moderate to fresh SE to S winds across the Bahamas and
through the NW zones Tue through early Thu.
