...DISCUSSION...

GULF OF MEXICO...

A cold front extends across the basin from 28N83W to 24N92W then
becomes stationary from that point to southwest to 19N95W.
Scattered to numerous showers prevail along and north of the
front mainly north of 24N. A surface ridge extends from the west
Atlantic across the remainder of the basin. Expect for the front
to stall and weaken from the central Florida coast to the Bay of
Campeche on today. Fresh to near-gale force northerly winds are
expected in the Bay of Campeche through this evening, instigated
by the ridge over eastern central Mexico.

Seismic activity with undersea volcano Kick'em Jenny, north of
Grenada near 12.18N 61.38W has steadily declined, and the alert
level for mariners has returned to normal, with an exclusion zone
of 1.5 km. Please see www.nadma.gd for additional information.

High pressure centered north of the area over the west Atlantic
will continue to shift east-northeast through Saturday morning,
allowing the continuation of fresh to strong trade winds in the
south-central Caribbean. Gentle to moderate trades are forecast
elsewhere through Wed night.

ATLANTIC OCEAN...

A surface ridge prevails across the west Atlantic with a 1023 mb
high centered near 36N57W. To the east, a surface trough extends
from 31N51W to 20N55W. Scattered showers are noted with this
feature mainly south of 25N between 51W-56W. A surface ridge
prevails across the remainder of the basin anchored by a 1024 mb
high centered near 30N25W.

High pressure northeast of the Bahamas will shift east-northeast
through this morning allowing for the winds and seas to diminish
gradually. A cold front will move off northeast Florida this
morning, stall north of the Bahamas through the day, and then
lift north of the area as a warm front from Sunday through Monday.
