------------------------------
At 800 PM AST (0000 UTC), the center of Hurricane Matthew was located near latitude 14.2 North, longitude 68.1 West. Matthew is moving toward the west near 15 mph (24 km/h). A westward to west-southwestward motion with some decrease in forward speed is expected during the next couple of days.

Maximum sustained winds remain near 75 mph (120 km/h) with higher gusts. Gradual strengthening is expected during the next 48 hours.

Hurricane-force winds extend outward up to 70 miles (110 km) from the center and tropical-storm-force winds extend outward up to 185 miles (295 km).

The minimum central pressure recently reported by an Air Force reconnaissance aircraft was 987 mb (29.15 inches).



HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are possible in Bonaire, Curacao, and Aruba tonight and Friday. Tropical storm conditions are possible over portions of the watch area in Colombia beginning Friday.

RAINFALL: Rainfall associated with Matthew will continue to diminish across the Lesser Antilles this evening. Isolated additional rainfall amounts of 2 to 4 inches are possible over the southern Windward Islands. Rainfall totals of 2 to 4 inches with isolated higher amounts are expected over Aruba, Bonaire and Curacao through Saturday.

SURF: Swells generated by Matthew are expected to affect portions of the coasts of Puerto Rico, Hispaniola, Aruba, Bonaire, Curacao, Venezuela, and Colombia 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.
