ISAAC ALMOST A HURRICANE MOVING FASTER TOWARDS THE ISLANDS

Interests in the Lesser Antilles should monitor the progress of Isaac.

At 500 PM AST (2100 UTC), the center of Tropical Storm Isaac was located near latitude 14.5 North, longitude 40.3 West.

Isaac is moving toward the west near 12 mph (19 km/h) and is expected to accelerate during the next 36 hours.

A westward motion is forecast to continue through the end of the week, with Isaac expected to move across the Lesser Antilles and into the eastern Caribbean Sea Wednesday night or Thursday.

Maximum sustained winds have increased to near 70 mph (110 km/h) with higher gusts. Additional strengthening is forecast, and Isaac is expected to become a hurricane tonight.

Weakening is anticipated to begin by the middle of the week while Isaac approaches the Lesser Antilles.

Tropical-storm-force winds extend outward up to 45 miles (75 km) from the center.

The estimated minimum central pressure is 997 mb (29.44 inches).
