At 200 PM EDT (1800 UTC), the center of Hurricane Melissa was
located near latitude 16.6 North, longitude 75.2 West. Melissa is
moving slowly toward the west-northwest near 1 mph (2 km/h). A slow
west-northwestward or westward motion is expected today 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.
Maximum sustained winds have increased to near 75 mph (120 km/h)
with higher gusts. Rapid intensification is forecast to occur over
the next couple of days and Melissa is forecast to become a major
hurricane by Sunday.
Hurricane-force winds extend outward up to 35 miles (55 km) from
the center and tropical-storm-force winds extend outward up to 125
miles (205 km).
The estimated minimum central pressure is 980 mb (28.94 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.
RAINFALL: Melissa is expected to bring total rainfall of 15 to 25
inches to portions of southern Hispaniola and Jamaica into
Wednesday, with local maxima of 35 inches possible across eastern
Jamaica and the Tiburon Peninsula of Haiti. Additional heavy
rainfall is likely beyond Wednesday but exact storm totals are still
uncertain. Catastrophic flash flooding and landslides are expected
across southwestern Haiti and portions of Jamaica, with the
possibility of catastrophic flood impacts also extending across the
remainder of southern Haiti into southern Dominican Republic.
For eastern Cuba, total rainfall of 5 to 10 inches, with local
amounts to 15 inches, are expected into Wednesday resulting in
life-threatening flash flooding and landslides. Additional heavy
rainfall is likely beyond Wednesday; uncertainty at that time range
precludes exact storm totals.
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: 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 7 to 11 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.
