SUMMARY OF WATCHES AND WARNINGS IN EFFECT: There are no coastal watches or warnings in effect. Interests in Atlantic Canada should monitor the progress of Erin and refer to local forecasts issued by Environment Canada. DISCUSSION AND OUTLOOK ---------------------- At 500 AM AST (0900 UTC), the center of Hurricane Erin was located near latitude 38.6 North, longitude 65.3 West. Erin is moving toward the northeast near 22 mph (35 km/h). A turn toward the east-northeast with an increase in forward speed is expected later today, followed by a turn back to the northeast on Sunday. On the forecast track, the center of Erin will pass south of Atlantic Canada today and tonight, and then race across the north Atlantic waters. Maximum sustained winds are near 90 mph (150 km/h) with higher gusts. Erin is likely to become post-tropical by tonight but remain a powerful hurricane-force low pressure system through the weekend. Erin remains a very large hurricane. Hurricane-force winds extend outward up to 125 miles (205 km) from the center and tropical-storm-force winds extend outward up to 370 miles (595 km). A wind gust to 56 mph (90 km/h) was recently reported at the L. F. Wade International Airport on Bermuda. The estimated minimum central pressure is 956 mb (28.23 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. WIND: Wind gusts to tropical storm force are possible in extreme southeastern Massachusetts during the next couple of hours. Gusts to gale force are possible along portions of the coast of Nova Scotia today and the Avalon Peninsula of Newfoundland on Saturday. SURF: Swells generated by Erin will affect the Bahamas, Bermuda, the east coast of the United States, and Atlantic Canada during the next several days. These rough ocean conditions are expected to cause life-threatening surf and rip currents. Please consult products from your local weather forecast office for more information. A depiction of rip current risk for the United States can be found at: hurricanes.gov/graphics_at5.shtml?ripCurrents STORM SURGE: Coastal flooding is expected at times of high tide along portions of the U.S. Mid-Atlantic and New England coasts through tonight, making some roads impassable.
