At 800 AM AST (1200 UTC), the center of Tropical Storm Matthew was
located near latitude 14.1 North, longitude 65.5 West. Matthew is
moving toward the west near 13 mph (20 km/h), and a general westward

next couple of days. On the forecast track, the center of Matthew
is forecast to pass to the north of Aruba, Bonaire, and Curacao
through Friday.

Reports from an Air Force Reserve Hurricane Hunter aircraft
indicate that the maximum sustained winds are near 70 mph (110 km/h)
with higher gusts. Gradual strengthening is forecast during the
next 48 hours, and Matthew is forecast to become a hurricane later
today or tonight.

Tropical-storm-force winds extend outward up to 185 miles (295 km)
primarily to the north and east of the center.

The estimated minimum central pressure based on data from
reconnaissance aircraft is 995 mb (29.38 inches).
