Although the official forecast continues to show a track east of
Florida, it is still too soon to rule out possible hurricane
impacts there. It is also too soon to know whether, or how, Matthew
might affect the remainder of the United States east coast.

DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 500 PM EDT (2100 UTC), the center of Hurricane Matthew was
located near latitude 14.6 North, longitude 74.8 West. Matthew is
moving toward the northwest near 5 mph (7 km/h). A turn toward the
north is expected tonight. On the forecast track, the center of
Matthew will approach southwestern Haiti and Jamaica on Monday.
Maximum sustained winds are near 145 mph (230 km/h) with higher
gusts. Matthew is a category 4 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Some fluctuations in intensity are possible
during the next couple of days, but Matthew is expected to remain a
powerful hurricane into Tuesday.
Hurricane-force winds extend outward up to 35 miles (55 km) from the
center and tropical-storm-force winds extend outward up to 205 miles
(335 km). NOAA data buoy 42058, in the central Caribbean, recently
reported a wind gust to 70 mph (112 km/h).
The estimated minimum central pressure is 945 mb (27.91 inches).
