DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Hurricane Erin was located near latitude 37.3 North, longitude 67.0 West. Erin is moving toward the east-northeast near 22 mph (35 km/h). A faster northeastward to east-northeastward motion is expected during the next couple of days. On the forecast track, the center of Erin will move over the western Atlantic between New England and Bermuda through early Friday, and then pass south of Atlantic Canada Friday and Saturday. Maximum sustained winds are near 100 mph (155 km/h) with higher gusts. Gradual weakening is forecast during the next couple of days, and Erin is expected to become post-tropical on Saturday. Erin remains a very large system. Hurricane-force winds extend outward up to 105 miles (165 km) from the center and tropical-storm force winds extend outward up to 320 miles (520 km). During the past few hours, wind gusts to tropical-storm force have been reported on Bermuda and on Nantucket Island, Massachusetts. The estimated minimum central pressure is 952 mb (28.12 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: Tropical storm conditions are expected on Bermuda through early Friday. Wind gusts to tropical storm force are likely through early Friday along the mid-Atlantic and southern New England coast. Gusts to gale force are possible along portions of the coast of Nova Scotia on Friday 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.
