At 1100 AM EDT (1500 UTC), the center of Hurricane Matthew was located near latitude 13.7 North, longitude 70.8 West. Matthew is moving toward the west-southwest near 12 mph (19 km/h). A westward motion at a slower forward speed is expected later today and tonight. A turn toward the west-northwest is forecast by Saturday night, followed by a turn toward the northwest by early Sunday. On the forecast track, the center of Matthew will pass north of the Guajira Peninsula later today and tonight and remain over the central Caribbean Sea through early Sunday.
Data from an Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds have increased to near 115 mph (185 km/h) with higher gusts. Matthew is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Little change in strength is forecast during the next 48 hours.
Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 195 miles (315 km).
The latest minimum central pressure based on data from the aircraft is 968 mb (28.59 inches).
