...ERIN MOVING QUICKLY WESTWARD, STILL FORECAST TO BECOME A HURRICANE IN A FEW DAYS...

At 11am EDT, Tropical Storm Erin was located 1,765 miles east of the northern Leeward Islands with maximum sustained winds of 45 mph and a minimum central pressure of 1006 mb.

Erin is moving quickly toward the west near 23 mph, and this general motion is expected to continue through Thursday before a west-northwestward motion is forecast into the weekend. Little change in strength is expected through tonight, but gradual strengthening is forecast to begin on Wednesday. Erin could become a Hurricane by late Thursday.

Since the last update, the forecast has again shifted to the south, increasing the risk for Erin to move closer to Puerto Rico and the U.S. Virgin Islands over the weekend.
