HAZARDS AFFECTING LAND
----------------------
WIND: *Hurricane conditions are expected to reach Jamaica and Haiti
tonight, and eastern Cuba Tuesday. *Tropical storm conditions are
expected to first reach Jamaica and Haiti later today and eastern
Cuba tonight, making outside preparations difficult or dangerous.
Preparations to protect life and property should be rushed to
completion. *Tropical storm conditions are expected along the
southern coast of the Dominican Republic within the warning area
beginning today. *Tropical storm conditions are expected to
reach the southeastern Bahamas early Tuesday with hurricane
conditions expected by late Tuesday.
Hurricane conditions are possible in the hurricane watch areas by
Tuesday night with tropical storm conditions possible on Tuesday.
Tropical storm conditions are also possible in the tropical storm
watch area in the Dominican Republic by late today.
RAINFALL: *Matthew is expected to produce total rain accumulations
of 15 to 25 inches across southern Haiti and the southwestern
portion of the Dominican Republic, with possible isolated amounts of
40 inches. *Across eastern Cuba and western Haiti, total rain
accumulations of 8 to 12 inches are expected with possible isolated
maximum amounts of 20 inches. *Across eastern Jamaica, total
rainfall of 5 to 10 inches is expected, with isolated maximum
amounts of 15 inches possible. This rainfall will likely produce
life-threatening flash floods and mudslides.
Matthew is expected to produce total rain accumulations of 8 to 12
inches over the southeastern Bahamas, with isolated maximum amounts
of 15 inches. Matthew is expected to produce total rain
accumulations of 2 to 5 inches, with isolated maximum amounts of
8 inches over the Turks and Caicos Islands.
Lower amounts are expected across the northeastern section of Haiti
and the Dominican Republic, with amounts ranging from 1 to 3 inches
with isolated amounts around 5 inches.
STORM SURGE: *The combination of a dangerous storm surge and large
and destructive waves could raise water levels by as much as the
following amounts above normal tide levels...
Southern Coast of Cuba east of Cabo Cruz...7 to 11 feet
South Coast of Haiti...7 to 10 feet
Northern Coast of Cuba east of Camaguey...4 to 6 feet
Jamaica...3 to 5 feet
Gulf of Gonave in Haiti...3 to 5 feet
Southern coast of the Dominican Republic...1 to 3 feet
Central and southeastern Bahamas...10 to 15 feet
Surge-related flooding depends on the relative timing of the surge
and the tidal cycle, and can vary greatly over short distances.
Large waves generated by Matthew will cause water rises to occur
well in advance of and well away from the track of the center.
SURF: *Swells generated by Matthew will continue to affect portions
of the coasts of Hispaniola, Jamaica, Aruba, Colombia, eastern Cuba,
and the Caribbean coastline of Central America during the next few
days. *These swells are likely to cause life-threatening surf and
rip current conditions. *Please consult products from your local
weather office.
