A Hurricane Watch is in effect for...
* Southwestern peninsula of Haiti from the border with the
Dominican Republic to Port-Au-Prince
* Jamaica

A Tropical Storm Warning in effect for...

A Hurricane Watch means that hurricane conditions are possible
within the watch area. A watch is typically issued 48 hours
before the anticipated first occurrence of tropical-storm-force
winds, conditions that make outside preparations difficult or dangerous.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area within 36 hours.

Interests elsewhere in Haiti, the Dominican Republic, and Cuba
should monitor the progress of Melissa.

For storm information specific to your area, please monitor
products issued by your national meteorological service.

DISCUSSION AND OUTLOOK
----------------------
At 800 AM EDT (1200 UTC), the center of Tropical Storm Melissa was
located by Air Force Reserve reconnaissance aircraft near latitude
15.5 North, longitude 74.9 West. Melissa is moving toward the
northwest near 5 mph (7 km/h). A slow northwest or north motion is
forecast during the next couple of days, followed by a westward turn
over the weekend. On the forecast track, Melissa is expected to
move closer to Jamaica and the southwestern portion of Haiti during
the next couple of days.

Maximum sustained winds are near 50 mph (85 km/h) with higher gusts.
Little change in strength is expected during the next day or so, but significant strengthening is expected by late Friday and over the
weekend. Melissa is forecast to become a hurricane in a couple of days.

Tropical-storm-force winds extend outward up to 115 miles (185 km)
from the center.

The estimated minimum central pressure is 1003 mb (29.62 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: Hurricane conditions are possible within the watch area in
Haiti and Jamaica beginning on Friday afternoon. Tropical storm
conditions are expected to begin in Jamaica earlier on Friday.

RAINFALL: Melissa is expected to bring 5 to 10 inches of rain to the
southern Dominican Republic, southern Haiti, and eastern Jamaica
through Sunday, with locally higher amounts possible. Additional
heavy rainfall is possible beyond Sunday; however, uncertainty in
Melissa's track and forward speed reduces confidence in exact
totals. Significant, life-threatening flash flooding and numerous
landslides are possible.

Across Puerto Rico, northern Dominican Republic, northern Haiti, and
western Jamaica, 2 to 4 inches of rain is expected through Sunday.
Flash and urban flooding will be possible through at least Sunday.
