DISCUSSION AND OUTLOOK ---------------------- At 200 AM EDT (0600 UTC), the center of Hurricane Isaias was located near latitude 35.0 North, longitude 78.1 West. Isaias is moving toward the north-northeast near 23 mph (37 km/h), and this general motion accompanied by an increase in forward speed is expected through today. On the forecast track, the center of Isaias will continue to move across eastern North Carolina early this morning. The center will move into southeastern Virginia around daybreak, near or along the coast of the mid-Atlantic states today, and continue across the northeastern United States tonight. Maximum sustained winds are near 75 mph (140 km/h) with higher gusts. Only gradual weakening is anticipated while Isaias moves north-northeastward near the mid-Atlantic coast today. Hurricane-force winds extend outward up to 25 miles (35 km) from the center, and tropical-storm-force winds extend outward up to 125 miles (205 km). A wind gust to 64 mph (104 km/h) was recently reported near Bogue, North Carolina. The estimated minimum central pressure is 992 mb (29.29 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Isaias can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4, WMO header WTNT44 KNHC, and on the web at www.hurricanes.gov/text/MIATCDAT4.shtml. 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... Little River Inlet SC to Ocracoke Inlet NC...2-4 ft Ocracoke Inlet to the North Carolina/Virginia border including Pamlico Sound, Albemarle Sound, Neuse and Pamlico Rivers...3-5 ft North of the North Carolina/Virginia border to Martha's Vineyard including the Chesapeake Bay, the Tidal Potomac River, Delaware Bay, Long Island Sound, Block Island Sound, Narragansett Bay, Buzzards Bay, and Vineyard Sound...1-3 ft The deepest water will occur along the immediate coast in areas of onshore winds, where the surge will be accompanied by large 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. WIND: Hurricane conditions will continue across portions of the hurricane warning area for another hour or two. Widespread tropical-storm conditions are expected in the tropical storm warning area from coastal North Carolina to the mid-Atlantic states, including portions of the Chesapeake Bay region, later today, with wind gusts to hurricane force possible. These winds could cause tree damage and power outages. Tropical storm conditions are expected to reach southern New England this afternoon and northern New England tonight and early Wednesday. Gale-force winds are expected to spread into southeastern Quebec tonight and Wednesday. See products issued by Environment Canada for more information. RAINFALL: The following rainfall accumulations are expected along and near the track of Isaias: Carolinas and the Mid-Atlantic: 3 to 6 inches, isolated maximum totals 8 inches. Eastern New York and western New England from Connecticut to New Hampshire: 2 to 4 inches, isolated maximum totals 6 inches. Western and northern Maine: 1 to 3 inches. Heavy rainfall along the East Coast, near the path of Isaias, will result in flash and urban flooding, some of which may be significant in the eastern Carolinas, Mid-Atlantic and Northeast through Wednesday. Widespread minor to moderate river flooding is possible across portions of the Carolinas and the Mid-Atlantic. Quick-responding rivers in Northeast will also be susceptible to minor river flooding. TORNADOES: A few tornadoes will be possible across eastern North Carolina early this morning, and from eastern Virginia northeastward into southern New England today. SURF: Swells generated by Isaias are affecting portions of the southeast coast of the United States and will spread northward along the Mid-Atlantic and Northeast coasts of the United States today. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
