DISCUSSION AND OUTLOOK
----------------------
At 800 PM EDT (0000 UTC), the center of Hurricane Melissa was
located near latitude 16.5 North, longitude 75.6 West. Melissa is
moving toward the west near 3 mph (6 km/h). A slow westward
motion is expected tonight through the end of the weekend. A turn
to the north and northeast is forecast on Monday and Tuesday. On
the forecast track, the center of Melissa is expected to move near
or over Jamaica during the weekend and early next week, and it
could be near or over eastern Cuba by the middle of next week.

Reports from NOAA and Air Force Reserve Hurricane Hunter aircraft
indicate that maximum sustained winds have increased to near 100 mph
(155 km/h) with higher gusts. Rapid intensification is forecast to
continue over the next day or so, and Melissa is forecast to become
a major hurricane tomorrow and is expected to still be a major
hurricane when making landfall in Jamaica early next week.

Hurricane-force winds extend outward up to 15 miles (30 km) from
the center and tropical-storm-force winds extend outward up to 160
miles (260 km).

The minimum central pressure estimated from the Hurricane Hunter
aircraft data is 971 mb (28.68 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Melissa can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC.

WIND: Tropical storm conditions are expected to begin in Jamaica by
tonight, with hurricane conditions expected by Sunday or Monday.
Tropical storm conditions are expected and hurricane conditions are
possible within the watch and warning area in Haiti later today.
Hurricane conditions are possible in the watch area in eastern Cuba
on Tuesday into Wednesday.

RAINFALL: Melissa is expected to bring total rainfall of 15 to 30
inches to portions of southern Hispaniola and Jamaica into
Wednesday, with local maxima of 40 inches possible. Additional
heavy rainfall is likely beyond Wednesday, but exact storm totals
are still uncertain. Catastrophic flash flooding and landslides are
probable across portions of southern Hispaniola and Jamaica.

For eastern Cuba, total rainfall of 6 to 12 inches, with local
amounts to 18 inches, are expected into Wednesday resulting in
life-threatening flash flooding and landslides. Additional heavy
rainfall is likely beyond Wednesday, but exact storm totals
are still uncertain.

STORM SURGE: Life-threatening storm surge is becoming more likely
along the south coast of Jamaica later in the weekend or early next
week. 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 potential for significant storm surge along the
southeast coast of Cuba early next week.

SURF: Swells generated by Melissa are expected to affect portions
of Hispaniola, Jamaica, and eastern Cuba during the next several
days. Please consult products from your local weather office.
