moderate convection is occurring within 120 nm

...CARIBBEAN SEA & LOCAL REGION...

A buiding pressure gradient in the Caribbean will
support moderate to fresh winds in the local region
with possibly strong winds in gusts. High pressure
will continue to build further until Saturday.
Limited moisture will restrict most of the
significant cloud development in the local
region and as a result, generally dry weather
will prevail.

Marine conditions: Calm seas are in place on the
protected sites with tranquil to moderate seas
on the south sites. Slight to moderate conditions
continue in place over the east to northwest coastal
regions with seas in the range of 2 to 3, locally
4 feet.
