Special features:
Tropical Storm Cristobal is moving over the north-central
Atlantic and poses no threat to the region.

A Tropical wave with an area of low pressure is located
about midway between the west coast of Africa and the
lesser Antilles. This system is producing a large area
of showers and thunderstorms and has a high chance in
the next 48 hours of developing further into a tropical
cyclone, as it moves west to west-northwestward over the
central tropical Atlantic waters.

A second Tropical wave is moving a few hundred kilometers
southwest of the Cabo Verde Islands in the far eastern
Atlantic. This system is producing some showers and
thunderstorms and has a medium chance of further
development during the next 7 days.

...CARIBBEAN SEA & LOCAL REGION...
A tropical wave is moving in the eastern Caribbean
with most weather to the north of the local region.
Some moisture of this system can induce a brief
shower during the day. However, mostly dry weather
will prevail during this forecast period.

Otherwise, Saharan Dust concentrations are low to
moderate. This will limit the visibility and induce
air of a lower quality. People sensitive to changes
in the air quality must continue to monitor this
feature and take the precautions, if necessary.

Marine conditions:
Smooth to slight seas are in place on the protected
south sites. Slight to moderate seas are noted on
the exposed south sides with seas of around 2 feet.
Generally moderate seas are noted over the east to
northwest coastal areas with seas of 4 to 7 feet,
locally reaching 8 feet.

Small Craft exercise caution over the east to
northwest coastal sections...
