DISCUSSION AND 48-HOUR OUTLOOK
At 800 PM AST (0000 UTC), the center of Tropical Storm Erika was located near latitude 16.7 North, longitude 59.5 West. Erika is moving toward the west near 17 mph (28 km/h). A west-northwestward motion at a slightly slower forward speed is expected over the next 48 hours. On the forecast track, the center of Erika will move near or over portions of the Leeward Islands tonight, move near the Virgin Islands and Puerto Rico on Thursday, and be near or just north of the north coast of the Dominican Republic on Friday.
Both NOAA and Air Force planes are currently investigating Erika, and the maximum sustained winds are still likely to be near 45 mph (75 km/h) with higher gusts. These winds are confined to heavy squalls to the southeast of the center. Little change in strength or perhaps some slight weakening could occur during the next 48 hours.
Tropical storm force winds extend outward up to 105 miles (165 km) to the east of the center.
The latest minimum central pressure just reported by an Air Force Hurricane Hunter aircraft was 1006 mb (29.71 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions are expected to first reach the warning area in the Leeward Islands tonight, and reach the Virgin Islands and Puerto Rico on Thursday. Tropical storm conditions are possible in the watch area in the Leeward Islands tonight and early Thursday. Tropical storm conditions could reach portions of the Dominican Republic, the southeastern Bahamas, and Turks and Caicos Islands on Friday.
RAINFALL: Erika is expected to produce total rain accumulations of 3 to 5 inches with maximum amounts of 8 inches across portions of the Leeward Islands, the Virgin Islands, Puerto Rico, and the Dominican Republic through Friday.
