DISCUSSION AND 48-HOUR OUTLOOK
At 200 PM EDT (1800 UTC), the eye of Hurricane Matthew was located
near latitude 13.2 North, longitude 73.4 West. While Matthew has
been moving erratically for the past couple of hours, overall the
center has drifted southward at around 2 mph (4 km/h). A faster
motion toward the west should resume later today, followed by a turn
toward the west-northwest by tonight. A turn toward the north-
northwest is forecast on Sunday, with northward motion expected on
Monday. On the forecast track, the center of Matthew will move
across the central Caribbean Sea today and Sunday, and approach
Jamaica and southwestern Haiti Sunday night and Monday.
Data from a NOAA Hurricane Hunter aircraft indicate that maximum
sustained winds are near 140 mph (220 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 through Monday.
Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 205
miles (335 km).
The latest minimum central pressure based on data from the NOAA
aircraft is 943 mb (27.85 inches).
