portion of Haiti, and these conditions will spread northward today.
Hurricane conditions are expected to reach eastern Cuba later today,
the southeastern Bahamas Tuesday evening, the central Bahamas on
Wednesday, and the northwestern Bahamas Wednesday night. Tropical
storm conditions are expected to continue spreading across the
remainder of Haiti today, eastern Cuba later this morning, the
southeastern Bahamas later today, and the central and northwestern
Bahamas Tuesday night and Wednesday, making outside preparations

Cuba tonight with tropical storm conditions possible later today.
Hurricane conditions are possible within the hurricane watch
area in Florida by late Thursday, with tropical storm conditions

RAINFALL: Matthew is expected to produce total rainfall amounts in
the following areas:
Southern Haiti and southwestern Dominican Republic...15 to 25
inches, isolated 40 inches
Eastern Cuba and northwestern Haiti...8 to 12 inches, isolated
Eastern Jamaica...4 to 6 inches, isolated 10 inches
The Bahamas...8 to 12 inches, isolated 15 inches
Turks and Caicos Islands...2 to 5 inches, isolated 8 inches
Northeastern Haiti and the Northern Dominican Republic...1 to 3
inches, isolated 5 inches

Middle to Lower Florida Keys....1 to 3 inches, isolated 5 inches
Life-threatening flash floods and mudslides are likely from this
rainfall in southern and northwestern Haiti, the southwestern
Dominican Republic, and eastern Cuba.
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...2 to 4 feet
Gulf of Gonave in Haiti...3 to 5 feet
Southern coast of the Dominican Republic...1 to 3 feet
The 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, eastern Cuba, and the
Caribbean coastline of Central America during the next few
days. Swells from Matthew will begin affecting portions of the
Bahamas on Tuesday. These swells are likely to cause life-
threatening surf and rip current conditions. Please consult
products from your local weather office.
