At 800 AM AST (1200 UTC), the center of Tropical Storm Erin was located near latitude 18.1 North, longitude 55.2 West. Erin is moving toward the west-northwest near 17 mph (28 km/h). This motion is expected to continue into the weekend. On the forecast track, the center of Erin is likely to move near or just north of the northern Leeward Islands over the weekend. Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Steady strengthening is expected during the next few days and Erin is forecast to become a hurricane later today, and it could become a major hurricane by this weekend. Tropical-storm-force winds extend outward up to 90 miles (150 km) mainly to the northeast of the center. The latest minimum central pressure estimated from NOAA Hurricane Hunter aircraft data is 998 mb (29.47 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Erin can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT5 and WMO header WTNT45 KNHC. RAINFALL: Tropical Storm Erin is expected to produce areas of heavy rainfall beginning late Friday and continuing through the weekend across the northernmost Leeward Islands, the U.S. and British Virgin Islands, as well as southern and eastern Puerto Rico. Rainfall totals of 2 to 4 inches, with isolated totals of 6 inches, are expected. This rainfall may lead to isolated flash and urban flooding, along with landslides or mudslides. For a complete depiction of forecast rainfall and flash flooding associated with Tropical Storm Erin, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at5.shtml?rainqpf WIND: Tropical storm conditions are possible within the watch area by early Saturday. SURF: Swells generated by Erin will begin affecting portions of the northern Leeward Islands, the Virgin Islands and Puerto Rico by this weekend, and will likely spread to the western Atlantic next week. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather forecast office.
