DISCUSSION AND OUTLOOK
----------------------
At 800 AM EDT (1200 UTC), the distinct eye of Hurricane Melissa was
located near latitude 16.4 North, longitude 78.0 West. Melissa is
moving toward the west near 3 mph (6 km/h). A slow turn toward the
northwest and north is expected today and tonight, followed by a
northeastward acceleration beginning on Tuesday and continuing
through at least Thursday. On the forecast track, the core of
Melissa is expected to move near or over Jamaica tonight and
Tuesday, across southeastern Cuba Tuesday night, and across the
southeastern Bahamas on Wednesday.
Reports from NOAA and Air Force Reserve Hurricane Hunter aircraft
indicate that maximum sustained winds are near 160 mph (260 km/h)
with higher gusts. Melissa is a category 5 hurricane on the
Saffir-Simpson Hurricane Wind Scale. Some additional strengthening
is forecast today, with fluctuations in intensity likely before
Melissa makes landfall on Jamaica early Tuesday. Melissa is
expected to reach Jamaica and southeastern Cuba as a powerful major
hurricane, and will still be at hurricane strength when it moves
across the southeastern Bahamas.
Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 195
miles (315 km).
The minimum central pressure from the Hurricane Hunter aircraft
data is 913 mb (26.96 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 occuring in Jamaica, and
destructive hurricane conditions are expected to begin tonight or
early Tuesday. Wind speeds atop and on the windward sides of hills
and mountains could be up to 30 percent stronger than the
near-surface winds indicated in this advisory, and in some elevated
locations could be even greater.
Tropical storm conditions are expected to begin in eastern Cuba on
Tuesday, with hurricane conditions expected to begin in the
hurricane warning area by Tuesday evening. Tropical storm conditions
are expected in Haiti late Tuesday and Wednesday.
Tropical storm and hurricane conditions are possible in the
southeastern and central Bahamas, as well as the Turks and Caicos
Islands, on Wednesday.
RAINFALL: 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 10 to 15 inches, with
local amounts to 20 inches, is expected today through Wednesday
resulting in life-threatening and potentially catastrophic flash
flooding with numerous landslides.
Over the Southeast Bahamas, total rainfall of 4 to 8 inches is
expected Tuesday into Wednesday resulting in areas of flash
flooding.
For a complete depiction of forecast rainfall associated with
Melissa, please see the National Weather Service Storm Total
Rainfall Graphic, available at
hurricanes.gov/graphics_at3.shtml?rainqpf
STORM SURGE: 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 potential for significant storm surge along the southeast
coast of Cuba late Tuesday or Wednesday. Peak storm surge heights
could reach 6 to 9 feet above normal tide levels, near and to the
east of where the center of Melissa makes landfall. This storm surge
will be accompanied by large and destructive waves.
Storm surge is possible in the southeastern Bahamas and Turks and
Caicos Islands on Wednesday.
SURF: 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
products from your local weather office.
