HURRICANE ISABEL CONTINUES NORTH-NORTHWEST; COASTAL WARNINGS UPDATED;
Preparations to Protect Life and Property Should Be Rushed to Completion (See the NOAA National Hurricane Center for the latest information on this storm. Complete advisories are posted at 11 a.m., 5 p.m., 11 p.m. and 5 a.m. All times are Eastern. Advisories are posted more frequently as the storm nears the USA mainland.) Sept. 17, 2003 � The NOAA National Hurricane Center in Miami, Fla., reports that at 11 a.m. EDT the center of Hurricane Isabel was located near latitude 30.0 north, longitude 72.6 west or about 400 miles south-southeast of Cape Hatteras, N.C. Isabel is moving toward the north-northwest near 9 mph. Some increase in forward speed is expected over the next 24 hours. On the forecast track, the center of Isabel is expected to make landfall in eastern North Carolina during the day Thursday. However, the precise timing and location of landfall is uncertain, and conditions will deteriorate over a large area well before the center reaches the coast. Tropical storm conditions are expected to reach the coastline late Wednesday night.

Little change in strength is forecast prior to landfall.
Hurricane force winds extend outward up to 115 miles from the center, and tropical storm force winds extend outward up to 315 miles.
The most recent minimum central pressure reported by reconnaissance aircraft was 957 mb, 28.26 inches. Storm surge flooding of 7 to 11 feet above normal tide levels, along with large and dangerous battering waves, is expected near and to the north of where the center crosses the coast. Storm surge flooding of 4 to 7 feet above normal tide levels is expected in southern Chesapeake Bay and the tidal portions of adjacent rivers. NOAA WARNS OF INLAND FLOODING THREAT "In the last 30 years, inland flooding has been responsible for more than half the deaths associated with tropical cyclones in the United States."
Ed Rappaport
Deputy Director, NOAA National Hurricane Center Consider the following: When it comes to hurricanes, wind speeds do not tell the whole story. Hurricanes produce storm surges, tornadoes, and often the most deadly of all—inland flooding. Read more... Storm total rainfalls of 6 to 10 inches, with locally higher amounts, are likely in association with Isabel. A hurricane warning remains in effect from Cape Fear, N.C., to Chincoteague, Va., including Pamlico and Albemarle sounds, and the Chesapeake Bay south of Smith Point. A hurricane warning means that hurricane conditions are expected within the warning area, generally within 24 hours.
All preparations to protect life and property should be rushed to completion in the hurricane warning area.
At 11 a.m. EDT, a tropical storm warning has replaced the hurricane watch south of Cape Fear to South Santee River, S.C., and north of Chincoteague to Sandy Hook, N.J., including Delaware Bay. A tropical storm warning has also replaced the hurricane watch for the Chesapeake Bay from Smith Point northward and for the Tidal Potomac.
