Discussion valid from 23/07/2021 to 24/07/2021


An Atlantic tropical wave extends its axis along 55W,
south of 18N, moving W near 15 to 20 kt. Scattered
moderate convection is evident South of 12N between
52W and 56W.

Another tropical wave is over the eastern Caribbean
along 65W,south of 18N, moving W at near 15 kt. No
significant convection is evident near this wave.


The relative tight pressure gradient between the
Atlantic high pressure and the low over northern
Colombia will support moderate to fresh, at times
strong to near gale force winds in gusts. A tropical
wave is moving through the eastern Caribbean and will
induce some moisture leading to a passing to brief
shower during the morning hours. Dry weather will
eventually prevail. Otherwise, Saharan Dust will
linger in the Caribbean Area during the next few
days, reducing the visibility. People with respiratory
illness and allergies should take this into account.

Marine conditions: slight seas are in place on the
protected sites with moderate seas on the south sites.
Generally moderate seas are in place over the east to
northwest coastal regions. Seas are in the range of
3 to 6 feet. Operators of small vessels should
continue to exercise caution over open waters.

Next update will be issued 24/07/2021
