Tropical Weather Discussion for North America, Central America
Gulf of Mexico, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 32N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.
Based on 0600 UTC surface analysis and satellite imagery through
1015 UTC.
...ITCZ/MONSOON TROUGH...
The monsoon trough extends from the African coast near 11N15W to
09N23W. The Intertropical Convergence Zone extends from 09N23W to
04N51W. Scattered moderate convection is from 04N-13N between
27W-50W.
...DISCUSSION...
GULF OF MEXICO...
Surface ridging prevails across the basin, anchored by a 1018 mb
high near 27N92W. Scatterometer data depicts gentle to moderate
anticyclonic winds across the basin. Winds will become light to
gentle across the western Gulf as the high moves eastward during
the next 24 hours. Southerly return flow will re-establish itself
across the northwest Gulf later today as the next frontal
boundary is expected to reach the southeast Texas, then stall and
weaken on Tuesday.
CARIBBEAN SEA...
A cold front extends into the northwest Caribbean from the
western Atlantic across eastern Cuba to Belize. Scattered showers
are noted within 200 nm southeast of the front. The eastern
Caribbean remains fairly tranquil under mostly clear skies. The
cold front will stall and dissipate from Haiti to Nicaragua
through Tuesday. Showers are expected with the front.
...HISPANIOLA...
Fair weather prevails across the island at this time. A frontal
boundary will continue approaching the island from the west
enhancing convection.
ATLANTIC OCEAN...
A cold front extends across the western Atlantic from 31N70W to
21N76W. This front is supported aloft by a deep mid-level trough
currently over the eastern US. Scattered showers are occurring
within 200 nm to the east of the front. Farther east, a 1010 mb
surface low is centered near 32N46W. A cold front extends from
the low to 22N58W. Scattered showers are noted with this front
between 40W-50W. The remainder of the basin is under the
influence of a surface ridge axis extending from the Azores to
22N39W.
