On the forecast track, the core of Erin is expected to pass to the east of the southeastern and central Bahamas today and tonight, and move between Bermuda and the east coast of the United States by the middle of the week. Maximum sustained winds are near 140 mph (220 km/h) with higher gusts. Erin is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Erin is likely to remain a dangerous major hurricane through the middle of this week. Erin is an unusually large hurricane.

HAZARDS AFFECTING LAND ---------------------- Key messages for Erin can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT5 and WMO header WTNT45 KNHC. RAINFALL: Outer bands of Erin will produce localized areas of heavy rainfall across portions of Hispaniola this evening and through Tuesday for the Turks and Caicos, the southeast Bahamas, and the easternmost central Bahamas. Additional rainfall of 2 to 4 inches, with locally higher amounts to 6 inches, are forecast. For a complete depiction of forecast rainfall and flash flooding associated with Erin, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at5.shtml?rainqpf WIND: Tropical storm conditions are expected through this evening across the Turks and Caicos Islands and the southeast Bahamas. Tropical storm conditions are possible in portions of the central Bahamas tonight through Tuesday. Tropical storm conditions are possible over portions of the North Carolina Outer Banks beginning late Wednesday. 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 will likely 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: Minor coastal flooding is possible in areas of onshore winds in the Turks and Caicos Islands and the southeast Bahamas. Near the coast, the surge will be accompanied by large waves. 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.
