SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Warning is in effect for... * Bermuda A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 800 AM AST (1200 UTC), the center of Hurricane Ernesto was located near latitude 24.5 North, longitude 69.3 West. Ernesto is moving toward the north near 13 mph (20 km/h). This general motion is expected to continue today, followed by a slower northeastward or northward motion on Friday and Saturday. On the forecast track, the center of Ernesto is expected to pass near or over Bermuda on Saturday. Maximum sustained winds remain near 85 mph (140 km/h) with higher gusts. Strengthening is forecast during the next day or two, and Ernesto could become a major hurricane by Friday. Ernesto is forecast to be a large hurricane near Bermuda on Saturday. Hurricane-force winds extend outward up to 45 miles (75 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km). The estimated minimum central pressure is 975 mb (28.79 inches) based on data from a dropsonde. HAZARDS AFFECTING LAND ---------------------- Key messages for Ernesto can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT5 and WMO header WTNT45 KNHC and on the web at hurricanes.gov/text/MIATCDAT5.shtml. WIND: Hurricane conditions are expected on Bermuda Saturday, with tropical storm conditions likely beginning Friday afternoon. STORM SURGE: A dangerous storm surge is expected to produce significant coastal flooding on Bermuda in areas of onshore winds. Near the coast, the surge will be accompanied by large and destructive waves. RAINFALL: Ernesto is expected to produce total rain accumulations of 4 to 8 inches in Bermuda with isolated maximum amounts up to 12 inches. This rainfall may result in considerable life-threatening flash flooding. SURF: Swells generated by Ernesto are affecting portions of the northern Leeward Islands, the Virgin Islands, Puerto Rico, the Dominican Republic, the Turks and Caicos Islands, and the southeastern Bahamas. These swells will spread toward Bermuda and the rest of the Bahamas later today. Swells are expected to reach the east coast of the United States tonight and continue into the weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
