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 1200 UTC surface analysis and satellite imagery through
1654 UTC.
...TROPICAL WAVES...
The eastern Atlantic tropical wave has been repositioned based on
wave diagnostic tools. The wave axis is now near 32W from 01N to
16N. Scattered showers are near the wave from 00N to 10N between
30W and 40W.
The central Atlantic tropical wave has been repositioned based on
wave diagnostic tools. The wave axis is now near 52W from 02N to
18N. Isolated showers are depicted from 08N to 12.5N between 48W
and 56.5W.
An eastern Caribbean tropical wave has its axis along 67.5W south
of 18N. It is moving westward at 10 to 15 kt. Isolated showers
and isolated thunderstorms are from 12N to 15N along the wave axis.
...MONSOON TROUGH/ITCZ...
The monsoon trough axis enters the Atlantic off the coast of
Africa near 18N16W and continues south-southwestward to 06N30W
and 06N41W. The ITCZ extends from 06N41W to 06N50W. Numerous
moderate to strong convection is just offshore the coast of Africa
from 02N to 14N and reaches west to near 23N. This convection is
in advance of the next tropical wave.
...GULF OF AMERICA...
A high pressure ridge extends westward to 87W from a subtropical
high located in the Atlantic. The pressure gradient between the
ridge and lower pressures across Mexico supports moderate to fresh
SE to S winds across much of the Gulf, except for gentle
southerly winds over the E Gulf. Seas are in the range of 4 to 7
ft over most of the Gulf, except for higher seas of 6 to 8 ft in
spots over the NW Gulf and seas 1 to 3 ft over the SE Gulf.
For the forecast, a ridge of high pressure extends from the
Atlantic westward across Florida to the central Gulf. The pressure
gradient between the high pressure and relatively lower pressures
over Texas and northeastern Mexico will generally support mostly
fresh southerly winds over the western and central Gulf, and
gentle to moderate winds over the eastern Gulf today. The fresh
winds over the western and central Gulf will diminish to gentle to
moderate speeds early next week. Winds over the eastern Gulf will
become light to gentle tonight.
...CARIBBEAN SEA...
The pressure gradient between broad central Atlantic high pressure
and lower pressures in northern South America is generally sustaining
fresh to strong trade winds over the south-central Caribbean and
the Gulf of Honduras, where seas are 6 to 9 ft. Moderate to fresh
trade winds and seas of 5 to 7 ft are over the eastern and
northwestern sections. Gentle to moderate winds and seas of 3 to
5 ft are across the remainder of the Caribbean.
An area of scattered showers and thunderstorms is noted in the
southwestern Caribbean from 10N to 14N between 76W and 83W. This
activity is related to the eastern extension of the East Pacific
monsoon trough that protrudes eastward across Costa Rica and to
the northwest part of Colombia. Isolated showers and thunderstorms
are elsewhere from 14N to 21N between 74W to 82W.
For the forecast, high pressure will prevail north of the area
into next week. The pressure gradient between the area of high
pressure and the Colombian low will support fresh to strong trade
winds and moderate to rough seas in the central Caribbean through
the forecast period, with highest winds and seas expected off the
coast of Colombia. Pulsing fresh to strong winds and moderate to
rough seas are expected in the Gulf of Honduras nightly through
Mon, pulsing briefly to near gale- force tonight. Moderate to
fresh winds are expected over much of the remainder of the
Caribbean through Mon night.
...ATLANTIC OCEAN...
A rather ill-defined trough extends from 31N28W to 26N36W. No
significant convection is present near the trough. High pressure
of 1024 mb is centered near 28.5N59W. High pressure covers the
waters north of about 21N. The related pressure gradient is
generally allowing for moderate to fresh trade winds along with
moderate seas to exist across much of the Atlantic south about 21N
as well as between the Bahamas and Cuba. Light to gentle
anticyclonic winds are north of 21N east of 72W while fresh
southwest winds are over the waters east of northern Florida to
near 75W. Seas are 3 to 5 ft north of 21N. Moderate to locally
fresh trades prevail over the tropical Atlantic along with seas 5
to 7 ft.
For the forecast west of 55W, high pressure across the basin will
shift slightly eastward tonight as a cold front moves across the
southeastern U.S. The front will move offshore northeast Florida
during the weekend, then stall and weaken. Fresh to strong
southwest winds are expected north of 30N and W of 72W through
tonight. Moderate to fresh winds will pulse to strong south of 22N
into early next week.
