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
A low pressure system centered near 37N47W is producing a large
area of cloudiness and disorganized thunderstorms east of the
center. Environmental conditions may become conducive for some
development by Wednesday. The system is forecast to move NE over
colder waters Thursday and Friday. There is medium potential for
this low to become a subtropical cyclone during the next 48
An Atlantic Ocean tropical wave is along 29W, from 08N to 20N,
moving west at 15 kt. Scattered rain showers are in the monsoon
trough area from 07N to 10N between 26W and 32W.
An Atlantic Ocean tropical wave is along 50W from 08N to 21N,
moving west at 15 kt. Scattered moderate convection is in the
monsoon trough area from 07N to 09N between 47W and 54W.
A Caribbean Sea tropical wave is along 69W from 10N to 22N,
moving west at 10-15 kt. Scattered moderate convection is along
the coast of N Hispaniola from 18N to 21N between 67W and 70W.
A Caribbean Sea tropical wave is along 80W from 10N to 22N,
moving west at 15 kt. The wave is enhancing scattered moderate to
isolated strong convection along the monsoon trough south of 12N.
The monsoon trough extends from the coast of Africa near 12N15W
to 09N20W to 10N40W. The ITCZ continues from 10N40W to 08N450W to
the coast of South America near 07N60W. Scattered moderate
convection is from 06N to 09N between 36W and 40W.
GULF OF MEXICO…
An upper level cyclonic circulation is over southern Mexico near
18N100W. Isolated showers are over the area. Upper level cyclonic
wind flow covers the Gulf of Mexico south of 24N and west of 90W.
A broad upper level anticyclonic circulation centered near 28N94W
spans the rest of the area. Widely scattered moderate rain
showers are over the NE Gulf from 26N to 31N between 82W and 87W.
On the surface a surface trough is over the NE Gulf from 31N85W to
26N88W. Another surface trough is over the Bay of Campeche from
24N90W to 18N93W. Scattered showers are within 90 nm of the trough
A nocturnal trough will develop during the evening hours in the
Yucatan Peninsula, before pushing offshore into the SW Gulf each
night. A surge of fresh to occasionally strong NE to E winds will
accompany this trough. The trough will become weaker by the middle
of the week, allowing the winds to diminish. A surface ridge will
support light to moderate E to SE winds across the remainder of
the basin through Friday night.
An upper level cyclonic circulation is along the coast of N Cuba
near 23N78W. Upper level diffluence is over Hispaniola enhancing
convection. Another upper level cyclonic circulation is over the
NW Caribbean near 19N85W. Upper level diffluence is over Honduras
and Nicaragua enhancing convection.
The monsoon trough is along 09N between 73W and 85W. Scattered
moderate to isolated strong convection is S of 12N between 74W and
83W, to include N Colombia and Panama.
Surface high pressure north of the area will maintain fresh to
strong winds in the south central Caribbean Sea through today.
Winds along the coast of Colombia and in the Gulf of Venezuela,
have begun to subside, and continue during the middle of the week
as western Atlantic Ocean high pressure slowly weakens.
Upper level cyclonic wind flow from an upper level trough covers
the Atlantic Ocean from Cuba and Hispaniola northward and west
of 70W. Isolated moderate to locally strong rain showers are in
the area of upper level cyclonic wind flow.
Upper level cyclonic wind flow associated with a trough covers
the Atlantic from 22N northward between 35W and 60W. Isolated
moderate to locally strong rain showers cover the Atlantic Ocean
north of 28N between 45W and 56W. A low pressure center and a
trailing surface trough are north of the area along 50W.
A surface ridge extends from a 1022 mb high pressure center near
30N66W. The tail end of a surface trough extends from 32N50W to
27N53W. Scattered moderate convection is within 90 nm of the
trough. Another 1023 mb high is over the E Atlantic near 36N29W
producing fair weather.
