DISCUSSION AND OUTLOOK
———————-
At 1100 AM AST (1500 UTC), the center of Tropical Storm Dorian was located by data from an Air Force Reserve reconnaissance aircraft and the Martinique radar near latitude 14.2 North, longitude 61.8 West. Dorian is moving toward the west-northwest near 13 mph (20 km/h), and this motion is expected to continue through tonight, followed by a turn toward the northwest on Wednesday. On the forecast track, the center of Dorian will move across the eastern and northeastern Caribbean Sea during the next few days, passing near or south of Puerto Rico on Wednesday, move near or over eastern Hispaniola Wednesday night, and move north of Hispaniola on Thursday. On Thursday night and Friday, the center of Dorian is forecast to move near the Turks and Caicos and southeastern Bahamas.

Maximum sustained winds remain near 50 mph (85 km/h) with higher gusts. Slow strengthening is forecast during the next 48 hours, and Dorian is forecast to be near hurricane strength when it moves close to Puerto Rico and eastern Hispaniola.

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

The estimated minimum central pressure is 1005 mb (29.68 inches).
