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
2050 UTC.
...MONSOON TROUGH/ITCZ...
The monsoon trough enters the Atlantic through the coast of Africa
near 11N15W and extends SW to near 05N19W. The ITCZ continues from
05N19W to 01N50W. Scattered moderate convection is noted from 03N
to 07N between 13W and 20W, and from 01N to 05N between 24W and
32W.
GULF OF AMERICA...
A frontal boundary is in the eastern Gulf, with a surface trough
over the NW waters. A 1017 mb high centered in the SW Gulf near
22N92W. The pressure gradient between the high and surface trough
is supporting moderate to fresh winds over the north central Gulf.
Light winds are in the vicinity of the high center. Gentle to
locally moderate winds are elsewhere. Seas are in the 3-5 ft range
in the north central Gulf, and 2-4 ft elsewhere.
For the forecast, the front will drift eastward before exiting
the basin on Tue. Pulsing moderate to fresh W winds are expected
across the northern Gulf through early Tue as a trough moves
eastward over the region. Otherwise, high pressure will build over
the basin this week. A tightening pressure gradient between
deepening low pressure in the central United States and the
aforementioned high will support fresh to locally strong S to SE
winds and rough seas offshore of Texas and Mexico Tue through late
week.
CARIBBEAN SEA...
The pressure gradient between high pressure in the central
Atlantic and the Colombian low is supporting fresh to strong E
winds in the south central Caribbean. Seas in this area are 8 to
12 ft. Moderate to fresh winds are elsewhere E of 80W, with seas
in the 6-9 ft range. Gentle to moderate winds, and seas of 4-6 ft,
are in the western Caribbean.
For the forecast, widespread fresh to strong E winds will prevail
over the central Caribbean through Tue afternoon as a tight
pressure gradient prevails between the Colombian low and high
pressure in the central Atlantic. Pulsing near-gale force winds
will be possible in the Gulf of Venezuela and offshore of
northwestern Colombia. Rough seas will accompany these winds, with
localized very rough seas occurring near and to the west of the
strongest winds. Winds and seas are expected to diminish midweek.
Moderate to fresh trade winds will pulse through late this week
in the eastern Caribbean. Easterly swell will bring rough seas
through the Atlantic passages into the eastern basin. Pulsing
fresh to strong E winds will develop in the Gulf of Honduras by
midweek.
ATLANTIC OCEAN...
A dissipating frontal boundary is over the waters from 31N58W to
30N70W. High pressure dominates the remainder of the discussion
waters. Light to gentle winds prevail N of 27N between 35W and
65W. Moderate to locally fresh winds prevail elsewhere. Seas are
in the 4-6 ft range N of 20N, and 6-9 ft S of 20N.
For the forecast west of 55W, fresh to strong S to SE winds and
rough seas will prevail offshore of Florida through Tue morning
as a tight pressure gradient prevails between a cold front in the
eastern Gulf of America and high pressure in the central
Atlantic. Periods of near-gale force winds will be possible
offshore of northern Florida tonight. The cold front will move
into the western Atlantic on Tue. Winds will turn to the W behind
the front and weaken before the front lifts northeastward out of
the region on Wed. Pulsing fresh to strong E winds are expected
each afternoon and evening offshore of northern Hispaniola through
Wed. Elsewhere, moderate to locally strong trade winds and rough
seas in mixed NE and SE swell will prevail south of 25N this week,
including across the Atlantic passages into the eastern
Caribbean.
