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 0000 UTC surface analysis and satellite imagery through
0400 UTC.
...MONSOON TROUGH/ITCZ...
The monsoon trough is analyzed from 14N17W to 04N20W. The ITCZ
continues from that point to 03S40W. Scattered moderate to
strong convection is noted within 200 nm on either side of the
ITCZ and W of 20W.
...GULF OF AMERICA...
A surface ridge prevails across the basin, anchored by a 1017 mb
high centered near 28N86W. Gentle to moderate southeast winds and
seas of 3 to 5 ft are noted over the western Gulf per latest
scatterometer satellite data, buoy observations and recent
altimeter satellite data. Light to gentle winds and seas of 2 ft
or less are over the rest of the basin.
For the forecast, a cold front will move off the Texas coast
overnight. Fresh to strong N to NE winds and building seas will
follow the cold front as it moves across the northern Gulf
through the early part of the week. The front will stall from the
Florida Straits to south Texas by late Mon then dissipate into mid
week. Fresh SE winds will return to the northwest Gulf by late
Thu.
...CARIBBEAN SEA...
A broad mid to upper-level trough stretches from the central
Atlantic southwestward to the central Caribbean. To its east,
a moist and unstable air mass is helping to promote scattered
showers over the eastern portion of the basin. The latest
scatterometer satellite data generally reveals gentle to moderate
trades east of about 72W. Seas are mostly 3 to 4 ft over this part
of the basin. Light to gentle winds prevail over the remainder of
the basin. Seas with these winds remain at 1 to 3 ft.
For the forecast, a weaker than usual pressure gradient will support
mainly gentle to moderate winds through the forecast period.
Fresh NE winds may develop early next week across the Windward
Passage associated with a late- season cold front moving into
Cuba.
...ATLANTIC OCEAN...
A surface trough is analyzed from 29N71W to 23N73W. To the east,
a broad 1026 mb high center is north of the area at 33N49W. This
feature controls the wind flow pattern across most of the western
and central Atlantic. Its associated gradient is maintaining light
to gentle winds north of 25N and between 35W and 45W. Seas with
these winds are about 4 to 6 ft. A 1010 mb surface low is analyzed
near 26N19W. Moderate to fresh northeast to east winds are over
the rest of the basin east of 35W along with seas of 5 to 7 ft.
For the forecast west of 55W, the ridging over the western
Atlantic will shift east tonight, ahead of a cold front that will
move off the northeast Florida coast on Sun. Fresh to strong N to
NE winds and rough seas will follow the front as it reaches a
position from Bermuda to Florida Straits by late Mon, and from
31N60W to central Cuba by late Tue. Winds will diminish through
mid week as the front stalls and dissipates along 22N. High
pressure will build between northeast Florida and Bermuda in the
wake of the front. Large N swell may linger near the dissipating
front Wed into Thu.
