DISCUSSION AND 48-HOUR OUTLOOK
At 1100 PM EDT (0300 UTC), the eye of Hurricane Matthew was located
near latitude 13.3 North, longitude 72.3 West. Matthew is moving
just south of due west near 7 mph (11 km/h). A turn toward the
west-northwest is forecast on Saturday, followed by a turn toward
the northwest on Sunday. On the forecast track, the center of
Matthew will move north of the Guajira Peninsula tonight, move
across the central Caribbean Sea on Saturday, and be approaching
Jamaica late Sunday.
Data from an Air Force Hurricane Hunter plane indicate that
the maximum sustained winds have increased to near 160 mph (260
km/h) with higher gusts. Matthew is a category 5 hurricane on the
Saffir-Simpson Hurricane Wind Scale. Some fluctuations in intensity
are possible this weekend, but Matthew is expected to remain a
powerful hurricane through Sunday.
Hurricane-force winds extend outward up to 45 miles (75 km) from the
center and tropical-storm-force winds extend outward up to 205 miles
The minimum central pressure estimated by a reconnaissance aircraft
