Tropical storm conditions are occurring in Jamaica, and
destructive hurricane conditions are expected to begin tonight or

Melissa is expected to bring rainfall of 15 to 30 inches
to portions of Jamaica and additional rainfall of 8 to 16 inches for
southern Hispaniola through Wednesday, with storm total local maxima
of 40 inches possible. Catastrophic flash flooding and numerous
landslides are likely. For eastern Cuba, storm total rainfall of=20

today through Wednesday resulting in life-threatening and=20
potentially catastrophic flash flooding with numerous landslides.
Over the Southeast Bahamas, total rainfall of 4 to 8 inches is=20

A life-threatening storm surge is likely along the
south coast of Jamaica tonight and on Tuesday. Peak storm surge
heights could reach 9 to 13 feet above ground level, near and to the
east of where the center of Melissa makes landfall. This storm surge
will be accompanied by large and destructive waves. There is a=20
potential for significant storm surge along the southeast coast of
Cuba late Tuesday or Wednesday. Peak storm surge heights could=20
reach 6 to 9 feet above normal tide levels, near and to the east=20
of where the center of Melissa makes landfall. This storm surge=20
will be accompanied by large and destructive waves. Storm surge=20
is possible in the southeastern Bahamas and Turks and Caicos=20
Islands on Wednesday.

Swells generated by Melissa are expected to affect portions of
Hispaniola, Jamaica, eastern Cuba, and the Cayman Islands during the
next several days, and the Bahamas, the Turks and Caicos Islands,
and Bermuda later this week. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult=20

A stationary front extends from Tampa Bay area to southern Alabama
to a 1012 mb low over southern Mississippi. The stationary front
then extends across SE Louisiana to the offshore waters of Texas
near 28N95W where it transitions to a warm front. A trough=20
extends southward from near the mouth of the Mississippi River to=20
22N85W. A few showers and thunderstorms are active over portions
of the Florida Panhandle coastal waters. A weak pressure gradient
in the Gulf is supporting light to gentle variable winds, except for
moderate to locally fresh E winds over the Straits of Florida.=20
Seas are generally slight to locally moderate.=20
For the forecast, a strong cold front is slated to enter the=20
northwestern Gulf Tue night into Wed and will progress=20
southeastward over the region through late week. Widespread fresh=20
to strong N to NW winds and rough seas will occur in the wake of=20
the front early Wed through Thu. Winds will likely reach gale=20
force along the coast of Mexico offshore of Tampico and Veracruz=20

...CARIBBEAN SEA...
Attention remains focused on Major Hurricane Melissa. Please read
the Special Features section for more information about this=20
powerful hurricane.=20
Outside of the area of Melissa in the central Caribbean, moderate
to fresh E to SE winds and 4 to 7 ft seas are noted over the eastern
Caribbean. Moderate to fresh NE winds and 4 to 6 ft seas are seen
over the northwest Caribbean. A few showers and thunderstorms are
active over the Gulf of Honduras. Heavier showers are over the
offshore waters of Costa Rica and Panama associated with both the
E Pacific monsoon trough and the outer bands of Melissa.
For the forecast, the core of Melissa is expected to move near or
over Jamaica tonight and Tuesday, across southeastern Cuba=20
Tuesday night, and across the southeastern Bahamas on Wednesday.=20
Some additional strengthening is forecast today, with fluctuations
in intensity likely before Melissa makes landfall on Jamaica=20
early Tuesday. Melissa is expected to reach Jamaica and=20
southeastern Cuba as a powerful major hurricane, and will still be
at hurricane strength when it moves across the southeastern=20
Bahamas. Melissa will change little in intensity as it moves near=20

...ATLANTIC OCEAN...
Please read the Special Features section for more information=20
about Major Hurricane Melissa.
A stationary front extends from south of Bermuda to just south of=20
Cape Canaveral Florida. The pressure gradient between high=20
pressure over the NE of the United States and Major Hurricane=20
Melissa located in the north-central Caribbean Sea is supporting=20
moderate to fresh E to SE winds mainly W of 65W, including the=20
Straits of Florida and the Great Bahama Bank. Seas are 6 to 9 ft=20
within these winds E and N of the Bahamas, and 4 to 5 ft in the=20
Straits of Florida. A few showers and thunderstorms are active=20
over the NE and central Florida offshore waters. The remainder
subtropical waters are under the influence of a broad ridge, which
is supporting moderate or weaker winds over the central and
eastern waters, except for fresh E to SE winds E of a surface
trough that extends from 17N49W to 26N41W. Scattered heavy showers
are also associated with this trough, which cover an area from 20N
to 30N between 30W and 46W.=20
For the forecast west of 55W, a low pressure system associated=20
with the stationary front will push offshore of the southeastern=20
U.S. today, leading to moderate to fresh E to SE winds east of 78W
this afternoon through Tue, and fresh to strong N to NW winds=20
behind the system offshore of northern Florida Tue through=20
midweek. Rough seas will build over this region by early Tue, with
seas expanding farther south and east Tue and Wed. Elsewhere,=20
Major Hurricane Melissa is strengthening in the north-central=20
Caribbean. On the forecast track, the core of Melissa is expected=20
to move near or over Jamaica tonight and Tuesday, across=20
southeastern Cuba Tuesday night, and across the southeastern=20
Bahamas on Wednesday. Elsewhere, a strong cold front will push=20
offshore of the southeastern U.S. by late week, supporting=20
increasing winds and building seas over the western Atlantic.=20
