Synopsis for Caribbean Sea and Tropical N Atlantic from

.SYNOPSIS...A tropical wave moving into the Gulf of Honduras
will bring showers and thunderstorms along with locally strong
winds and higher seas to the gulf and adjacent waters of the NW
Caribbean this weekend. Otherwise, Atlantic high pressure in
combination with low pressure over northern Colombia will
maintain fresh to strong trades along with moderate to locally
rough seas across much of the central Caribbean through early
next week.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A stationary front extends from just W of Bermuda to
just N of Daytona Beach, Florida, with a surface trough
extending southward offshore the Florida coast. These features
are leading to scattered thunderstorms northward from the NW
Bahamas, which will continue through Monday, as low pressure
forms along the front near the Florida coast and tracks ENE along
it. Behind the low, NE to E winds will increase to fresh to
strong N of the boundary, mainly N of 29N and W of 77W Sun night
into Tue. Elsewhere, high pressure will remain in control of the
general weather pattern providing for a gentle to moderate
anticyclonic wind flow.
