DISCUSSION AND OUTLOOK ---------------------- At 1100 AM EDT (1500 UTC), the eye of Hurricane Erin was located near latitude 30.1 North, longitude 73.7 West. Erin is moving toward the north near 13 mph (20 km/h). A turn toward the north-northeast is expected later today and tonight, followed by a faster motion toward the northeast and east-northeast by Thursday and Friday. On the forecast track, the center of Erin will move over the western Atlantic between the U.S. east coast and Bermuda today through early Friday, and then pass south of Atlantic Canada Friday and Saturday. Maximum sustained winds have increased to near 110 mph (175 km/h) with higher gusts. Some additional strengthening is likely during the next day or so, and Erin could become a major hurricane again by tonight. Weakening is likely to begin by Friday, but Erin is forecast to remain a hurricane into the weekend. Erin is a large hurricane. Hurricane-force winds extend outward up to 90 miles (150 km) from the center and tropical-storm-force winds extend outward up to 265 miles (425 km). The minimum central pressure estimated from Air Force Hurricane Hunter observations is 941 mb (27.79 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 over portions of the North Carolina Outer Banks and the Virginia coastline beginning late today. Elsewhere along the mid-Atlantic and southern New England coast, wind gusts to tropical storm force are likely Thursday through early Friday. Tropical storm conditions are possible on Bermuda Thursday and Friday. 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: The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Cape Lookout to Duck, North Carolina...2 to 4 ft The deepest water will occur along the immediate coast where the surge will be accompanied by large and dangerous waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. For a complete depiction of areas at risk of storm surge inundation, please see the National Weather Service Peak Storm Surge Graphic, available at hurricanes.gov/graphics_at5.shtml?peakSurge.
