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. Interests in Atlantic Canada should monitor the progress of Ernesto. 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 32.6 North, longitude 64.6 West. Ernesto is moving toward the north-northeast near 9 mph (15 km/h), and this general motion is expected today. A faster northeastward motion is then expected late this weekend into early next week. On the forecast track, the center of Ernesto is expected to slowly depart Bermuda today and move near or east of Newfoundland Monday night. Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Little change in strength is forecast today. Some re-intensification is possible late in the weekend before weakening begins on Monday. Ernesto is a large tropical cyclone. Hurricane-force winds extend outward up to 70 miles (110 km) from the center and tropical-storm- force winds extend outward up to 240 miles (390 km). The estimated minimum central pressure based on dropsonde data is 974 mb (28.76 inches). 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 through the next several hours. Due to Ernesto`s large size and slow motion, strong winds will continue on the island through most of today into this evening. 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 6 to 9 inches or 150 to 225 mm on Bermuda. This rainfall will likely result in considerable life-threatening flash flooding, especially in low-lying areas on the island. SURF: Swells generated by Ernesto are affecting portions of the the Bahamas, Bermuda, and the east coast of the United States. These swells will likely reach portions of Atlantic Canada today. Life-threatening surf and rip current conditions are likely in these areas during the next couple of days. Please consult products from your local weather office, and stay out of the water if advised by lifeguards. NEXT ADVISORY ------------- Next complete advisory at 1100 AM AST. $$ Forecaster Berg |
