...SPECIAL FEATURES...

...CARIBBEAN GALE WARNING...

Gale-force winds will pulse once again today across the south
central Caribbean within 90 nm of the coast of Colombia. These
conditions will subside by this afternoon 27/1800 UTC. The gale
will continue pulsing through the next 7 days. Please refer to the
High Seas forecast product under the AWIPS/WMO headers
HSFAT2/FZNT02 KNHC for more details.

...GALE WARNING IN THE CENTRAL ATLANTIC...

A cold front will extends from 31N41W to 24N46W in 24 hours on
28/0600 UTC. With this, gale-force winds are expected north of
30N between 47W and 53W. Seas in this area will range between
10-14 ft. Please refer to the High Seas Forecast product under the
AWIPS/WMO headers HSFAT2/FZNT02 KNHC for more details.

...MONSOON TROUGH/ITCZ...

The monsoon trough passes through the coastal sections of Liberia
near 06N10W to 04N18W. The ITCZ continues from 04N18W to 02N30W to
the coast of Brazil near 00N50W. Scattered moderate convection is
from 00N-03N between 01W-05W, from 00N-04N between 12W-20W, and
from 00N-03N between 25W-40W.

GULF OF MEXICO...

A cold front is inland over S Texas. Moderate to fresh
southeasterly winds prevail across the basin, as noted in the
latest scatterometer data. Radar imagery shows scattered moderate
convection over the northeast Gulf north of 26N between 83W-91W.

A cold front will move off the Texas coast late today. The front
will stall and linger across the NW gulf through the weekend,
drifting E again early next week.

CARIBBEAN SEA...

Refer to the section above for details about the pulsing Gale
Warning currently in effect for the south-central Caribbean.
Scatterometer data depicts moderate to fresh trades across the
remainder of the area. Low-topped trade wind showers are quickly
moving across the basin.

Strong trade winds will prevail across the S central
Caribbean through Mon night, increasing to gale force along the
NW coast of Colombia at night. Trade winds will increase across
the entire region today through Mon night as high pres builds
over the western Atlantic.

ATLANTIC OCEAN...

A cold front passes through 31N45W to 25N60W to 24N69W. Scattered
showers are within 90 nm of the front. A 1029 mb high is centered
over the northeast Atlantic near 38N19W.

Over the W Atlantic, a surface high shifting N of the area will
help usher in increasing winds and building seas through Fri. The
high pressure center will shift eastward and weaken as a weak cold
front drops S of 31N this weekend into early next week. This will
allow for a decrease in winds and seas over the area.
