At 800 AM AST (1200 UTC), the center of Tropical Storm Matthew was

is forecast to pass to the north of Aruba, Bonaire, and Curacao
through Friday.

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)
