DISCUSSION AND OUTLOOK
----------------------
At 500 AM EDT (0900 UTC), the center of Hurricane Melissa was
located near latitude 17.2 North, longitude 78.3 West. Melissa is
moving toward the north-northeast near 5 mph (7 km/h). A turn toward
the northeast with an increase in forward speed is expected later
today, followed by a faster northeastward motion on Wednesday and
Thursday. On the forecast track, the core of Melissa is expected to
move over Jamaica today, across southeastern Cuba Wednesday morning,
and across the southeastern or central Bahamas later on Wednesday.
Maximum sustained winds are near 175 mph (280 km/h) with higher
gusts. Melissa is a category 5 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Some fluctuations in intensity are likely
before Melissa makes landfall on Jamaica later today. However,
Melissa is expected to reach Jamaica and southeastern Cuba as an
extremely dangerous major hurricane, and it 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). Norman Manley International Airport in Kingston,
Jamaica, recently reported a sustained wind of 39 mph (63 km/h) and
a gust of 58 mph (93 km/h). Sangster International Airport in
Montego Bay, Jamaica, recently reported a sustained wind of 40 mph
(65 km/h) and a gust of 56 mph (91 km/h).
The estimated minimum central pressure is 901 mb (26.61 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 occurring in Jamaica, and
catastrophic hurricane-force winds are expected to begin this
morning. Within the eyewall, total structural failure is likely,
especially in higher elevation areas where wind speeds atop and on
the windward sides of hills and mountains could be up to 30 percent
stronger.
Tropical storm conditions are expected to begin in eastern Cuba
today, with hurricane conditions expected in the hurricane warning
area starting tonight into Wednesday morning. Tropical storm
conditions are expected in Haiti later today and Wednesday.
Hurricane conditions are expected in the southeastern and central
Bahamas on Wednesday. Tropical storm conditions are expected and
hurricane conditions are possible in 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 6 to 12 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 20 inches, with
local amounts to 25 inches, is expected into Wednesday resulting in life-threatening and potentially catastrophic flash flooding with
numerous landslides.
Over the Southeastern Bahamas and the Turks and Caicos, rain is
expected to develop later today and continue into Wednesday. Total
rainfall of 5 to 10 inches is expected to result 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 today. 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. On the northwest coast
of Jamaica, near Montego Bay, there is the possibility of 2 to 4
feet of storm surge above ground level.
There is a potential for significant storm surge along the southeast
coast of Cuba late today or Wednesday. Peak storm surge heights
could reach 7 to 11 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 of 4 to 6 ft above normally dry ground 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, likely causing life-threatening surf and rip
current conditions. These swells will reach the Bahamas, the Turks
and Caicos Islands, and Bermuda later this week. Please consult
products from your local weather office.
