.SYNOPSIS...A weak ridge will prevail N of the area along 29N
through Mon. High pressure will then build westward across the
regional Atlantic and into Florida Tue through Thu. This pattern
will continue to support pulsing fresh to strong trades and
rough seas across the south-central Caribbean through early Tue
then expand across much of the central basin late Tue through
Thu. Fresh E winds are expected across the Gulf of Honduras
through Fri, pulsing to locally strong tonight. Moderate to
fresh winds and moderate seas are expected in the eastern
Caribbean through Tue while gentle to moderate winds and slight
to moderate seas will prevail NW portions.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A weak ridge along 29N will dominate the forecast
area east of 70W through Mon. High pressure will then build
westward across the region and into Florida Tue through Thu in
the wake of a trough of low pressure developing across the NW
zones tonight. This trough is forecast to move westward across
Florida during the next day or so, and into the northeastern
Gulf by Tue. Active weather is expected in association with this
system over the waters west of 75W through Tue. The pressure
gradient between the Atlantic ridge building westward and the
trough of low pressure will support moderate to fresh SE to S
winds across the Bahamas and through the NW zones Tue through
early Thu.
