Tropical Weather Discussion for North America, Central America
Gulf of America, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 31N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.
Based on 1800 UTC surface analysis and satellite imagery through
2100 UTC.
...SPECIAL FEATURES...
Caribbean Sea Gale Warning: The pressure gradient between high
pressure N of the area and the Colombian low will support strong
to near gale- force easterly trade winds and rough seas across the
south- central Caribbean. Winds will pulse to gale force over
these waters at night with the added component of nocturnal
drainage flow. Locally very rough seas are expected with these
winds.
Central and Eastern Atlantic Significant Swell Event: A previous
gale force wind event off the Canary Islands generated a large NE
swell with very rough seas greater than 12 ft. The swell has
propagated from this source region, with these very rough seas
currently over the waters from 10N to 20N between 33W and 50W.
The seas, currently peaking near 14 ft, are gradually subsiding
and will decrease below 12 ft by Tue.

...MONSOON TROUGH/ITCZ...
The monsoon trough enters the Atlantic off the coast of Africa
near 08N13W and continues southwestward to 03N19W. The ITCZ
extends from 03N19W to the coast of Brazil near 04S38W. Scattered
to numerous moderate to strong convection is noted S of 06N
between 10W and 40W.
...GULF OF AMERICA...
A weak frontal boundary extends from the Florida Keys westward to
25N84W and to near 24N87W. Isolated showers and thunderstorms are
along and near the boundary. Winds over the Gulf are moderate or
weaker, with slight to moderate seas.
For the forecast, the frontal boundary will slowly move
southeastward and exit the basin tonight while becoming diffuse.
Afterward, an expansive area of strong high pressure will build
west- southwestward from the central N Atlantic over the area
starting tonight and hold through the upcoming week. Its related
pressure gradient will support moderate to fresh east to southeast
winds across the Gulf. Locally strong winds will occur at night
off the northern Yucatan Peninsula starting Tue.
...CARIBBEAN SEA...
Please see Special Features section above for pulsing gales in the
south central Caribbean.
A broad ridge of high pressure extends from a 1033 mb high center
over the central Atlantic to the western Atlantic waters N of the
area. The pressure gradient between this area of high pressure and
the Colombian low is supporting fresh to strong winds over the
south central Caribbean, and moderate to fresh winds elsewhere E
of 80W. Light to gentle winds are over the western Caribbean. Seas
are in the 7-10 ft range over the south central Caribbean, and
6-8 ft elsewhere E of 80W. W of 80W, seas are in the 2-4 ft range.
For the forecast, the pressure gradient over the area will
support fresh to near gale- force trades and moderate to rough
seas across the central and eastern Caribbean through the forecast
period.
