Sept.
18, 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 34.4 north, longitude 75.7
west or about 55 miles south of Cape Hatteras, N.C. This position is
also about 50 miles east-southeast of Cape Lookout, N.C. The eyewall
of Isabel, where the strongest winds are located, is currently coming
ashore along the southern Outer Banks. (Click NOAA satellite

Isabel
has a very large eye, and winds within the eye will diminish before
increasing rapidly as the back edge of the eye passes by. People are
strongly cautioned not to venture out during the eye passage unless
absolutely necessary.
Isabel
is moving toward the northwest near 18 mph, and this motion is expected
to continue Thursday with a turn to the north-northwest overnight. On
the forecast track, the center of Isabel is expected to make landfall
between Cape Hatteras and Cape Lookout, N.C., within the next couple
of hours and move inland over eastern North Carolina and southeastern
Virginia over the next 24 hours. (Click NOAA satellite image

Maximum sustained winds are near 100 mph with higher gusts. Little change
in strength is expected prior to landfall. Although Isabel will weaken
as it moves inland, unusually strong winds, with gusts to hurricane
force, may be experienced far inland over the elevated terrain of Northern
Virginia and Maryland, as well as on high-rise buildings and other structures.
Hurricane
force winds extend outward up to 115 miles from the center, and tropical
storm force winds extend outward up to 345 miles. (Click NOAA

At 11 a.m. EDT, Cape Hatteras reported a wind gust of 79 mph, and a
gust to 85 mph was reported at Ocracoke, N.C.
The most
recent minimum central pressure reported by a hurricane hunter aircraft
was 956 mb, 28.23 inches.
Storm surge flooding of 5 to 8 feet above normal tide levels, along
with extremely 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 8 feet above normal tide levels is expected in the
Chesapeake Bay and the tidal portions of adjacent rivers. Ham radio
operators have reported a storm surge of close to 4 feet on the Neuse
River at New Bern, N.C.
Storm
total rainfalls of 6 to 10 inches, with locally higher amounts, are
likely in association with Isabel. (Click NOAA tracking map

There is a threat of isolated tornadoes over eastern North Carolina,
eastern Virginia and southeastern Maryland Thursday.
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 tropical storm warning remains in effect north of Chincoteague to
Moriches Inlet, N.Y., including Delaware Bay. A tropical storm warning
remains in effect south of Cape Fear to South Santee River, S.C., for
the Chesapeake Bay from Smith Point northward and for the Tidal Potomac.
