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
2230 UTC.
...TROPICAL WAVES...
A tropical wave is W of the Cape Verde Islands near 30W,
extending from 03N to 17N, and moving W at around 15 kt.
Scattered showers and isolated thunderstorms are seen from 06N to
11N between 29W and 34W.
A tropical wave is across the eastern Caribbean, south of 19N,
moving W at 10-15 kt. Scattered moderate isolated strong convection
is noted from 10N to 16N between 61W and 70W.
...MONSOON TROUGH/ITCZ...
The monsoon trough enters the Atlantic near 16.5N16.5W and
continues southwestward to 08N34W. The ITCZ extends from 08N34W
to 05.5N54W. Aside from the convection associated with the
tropical waves, scattered moderate convection is evident within 60
nm N and 120 nm S of the ITCZ between 34W and 54W.
...GULF OF AMERICA...
High pressure extends a ridge across the western Atlantic SW
across the SE U.S. and to the central Gulf waters, anchored by a
1019 mb high in the central Gulf. This supports light to gentle
winds and slight seas across most of the basin, except for gentle
to moderate E to SE winds over the Bay of Campeche associated with
a surface trough. Aside from the moderate winds, the surface
trough in the Bay of Campeche is generating scattered showers and
isolated thunderstorms in the SW Gulf, while scattered showers
extend across the NE Gulf.
For the forecast, a weak surface ridge will continue to dominate
the Gulf waters through the forecast period supporting gentle to
moderate winds over the western Gulf and light to gentle winds
over the eastern Gulf. The exception will be pulsing winds
reaching fresh to locally strong speeds off the northwestern
Yucatan Peninsula nightly through early next week. Slight to
moderate seas are expected through the period.
...CARIBBEAN SEA...
Abundant tropical moisture accompanying the tropical wave along
65W has encountered favorable upper level conditions produce by an
elongated middle to upper-level low pressure just N of the Greater
Antilles to produce scattered showers and thunderstorms across
much of the eastern Caribbean east of 70W. This upper level
feature is also supporting strong scattered afternoon convection
across Hispaniola and Cuba. The pressure gradient between the
subtropical ridge north of the basin and the Colombian Low
continue to support fresh to strong easterly winds and seas of
8-11 ft in the central to SW Caribbean. The strongest winds and
highest seas are found off NW Colombia. Moderate to fresh easterly
winds and moderate seas are occurring in the eastern Caribbean
away from areas of convection associated with the tropical wave
near 65W. Seas are 4 to 6 ft there. Elsewhere, moderate or
lighter winds and slight to moderate seas prevail. The E Pacific
extension of the monsoon continues to support scattered strong
convection over the waters near the coasts of Costa Rica and
Panama.
For the forecast, the pressure gradient between the Atlantic
ridge north of the basin and the Colombian Low will continue to
support fresh to strong trade winds and moderate to rough seas
over the central Caribbean through Tue night. Expect winds to
reach near- gale force each night offshore of Colombia and in the
Gulf of Venezuela. Otherwise, moderate to fresh trades will
continue in the eastern Caribbean while moderate or weaker winds
will prevail over the NW part of the basin. Active showers and
thunderstorms are expected across the SE Caribbean tonight
accompanying the tropical wave along 65W. The wave and its
associated moisture will reach Hispaniola and the central
Caribbean waters on Sat.
...ATLANTIC OCEAN...
A weakening frontal boundary continues to meander just north of
the area along 32N-33N between 57W and 73W. A surface trough,
remnants of a stationary front, extends from a 1018 mb low
pressure near 32N73W to the SE FL coast. Scattered showers and
a few thunderstorms are seen along and near the trough axis, while
scattered showers and thunderstorms previal across much of the
central and northwestern Atlantic between the stalled front and
27N, from 46W to 72W, and focused along another surface trough
from 31N66W to 29N60W to 30N56W. A middle to upper-level low
north of the Dominican Republic is also aiding in the development
of strong scattered showers and isolated thunderstorms across
Hispaniola and Cuba. Otherwise, the Azores High extends a ridge
southwestward across the subtropical Atlantic waters, thus
supporting mainly moderate to fresh trades and moderate seas
across much of the waters S of 20N. Fresh to locally strong trades
prevail across areas from 10N to 15N between 50W and the Lesser
Antilles, where seas are 6 to 8 ft. Gentle to moderate trades and
3-6 ft seas prevail across much of the remaining Atlantic.
For the forecast west of 55W, a surface trough across the NW
waters to SE Florida will gradually dissipate tonight while
drifting northwestward toward the southeastern U.S. coast. The
Atlantic ridge will then build westward into central Florida
through early next week. This pattern will support moderate to
fresh E to SE trade winds S of 22N, and moderate or weaker winds
elsewhere.
