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 0600 UTC surface analysis and satellite imagery through
1000 UTC.
...SPECIAL FEATURES...
Western and Central Atlantic Large Swell:
A shear line extends from 31N44W to 20N71W. Residual large NE
swell along with wind waves are sustaining seas of 12 to 15 ft up
to 300 nm northwest of the shear line east of 68W. As both swell
and wind waves decline further through today, this should allow
seas to drop below 12 ft by this evening.
Please refer to the latest NWS High Seas Forecast issued by the
National Hurricane Center, at the following website:
MIAHSFAT2.shtm'>https://www.nhc.noaa.gov/text/MIAHSFAT2.shtm for more details.
...MONSOON TROUGH/ITCZ...
The monsoon trough is confined to Africa. The ITCZ extends from
02N17W to 04S38W. Scattered moderate to strong convection is
observed along the ITCZ and E of 26W.
...GULF OF AMERICA...
A broad subtropical ridge over the western Atlantic extends
southwestward across northern Florida to near Tampico, Mexico.
Fresh to strong E winds and seas of 5 to 7 ft are present across
the Florida Straits. Moderate to fresh NE to E winds and 3 to 5
ft seas prevail north of the Yucatan Peninsula and in the eastern
Bay of Campeche. Gentle to moderate E to SE winds and seas at 2
to 4 ft prevail for the rest of the Gulf.
For the forecast, moderate to fresh E to SE winds and moderate
seas are expected over the eastern Gulf through Sat night. Over
the western half of the Gulf, moderate to fresh SE winds are
forecast, except for strong E to SE winds off the northern Yucatan
Peninsula at night. A cold front may enter the western Gulf
Sunday with strong winds and rough seas expected in its
vicinity.
...CARIBBEAN SEA...
Strong to near gale-force ENE trades and 8 to 10 ft seas are
evident off northwestern Colombia, while fresh to strong NE trades
and seas of 4 to 7 ft dominate the lee of Cuba, north-central and
the rest of the south-central basin. Fresh to strong ENE winds
and 7 to 9 ft seas are noted in and southwest of the Windward
Passage. Gentle to moderate NE to E winds and seas at 3 to 5 ft
prevail elsewhere in the Caribbean Sea.
For the forecast, the pressure gradient between high pressure N
of the area and the Colombian low will support fresh to strong
winds and rough seas offshore Colombia through the forecast
period. This pattern will also support fresh to strong NE winds in
the lee side of Cuba, the Windward Passage, and south of
Hispaniola through Thu night.
...ATLANTIC OCEAN...
Refer to the Special Features section for information about the
large swell.
A shear line is analyzed from 31N44W to 20N71W. Scattered showers
are found along the shear line mainly between 50W-63W. Besides
the very rough seas mentioned in the Special Features section,
fresh to strong NE winds and 8 to 12 ft seas are up to 300 nm
northwest of the boundary, except gentle to moderate SE winds with
5 to 8 ft seas are found north of 27N and west of 72W. To the
east, north of 20N between 35W and the shear line, moderate to
fresh NE winds and 7 to 9 ft seas in large northerly swells
prevail. Gentle to moderate NE winds and 5 to 8 ft seas exist for
the remainder of Atlantic from 00N to 20N between 35W and the
Lesser Antilles.
For the forecast west of 55W, strong high pressure will prevail
across the western Atlantic into this weekend. Fresh to strong NE
to E winds, and rough to very rough seas, are expected across
most of the offshore forecast waters through the remainder of the
week. Winds will diminish this weekend with seas slowly subsiding.
