DISCUSSION AND OUTLOOK
At 500 PM EDT (2100 UTC), the center of Tropical Storm Isaias was
located by an Air Force Reserve reconnaissance aircraft and NOAA
Doppler weather radars near latitude 27.8 North, longitude 79.8
West. Isaias is moving toward the north-northwest near 9 mph (15
km/h), and this general motion is expected to continue through
tonight. A turn toward the north and north-northeast along with an
increase in forward speed is anticipated on Monday and Tuesday. On
the forecast track, the center of Isaias will pass just to the east
of the Florida east coast through tonight. The center of Isaias
will move offshore of the coast of Georgia and southern South
Carolina on Monday, move inland over eastern North Carolina
Monday night and move along the coast of the mid-Atlantic states on
Data from the aircraft and the Melbourne, Florida, Doppler radar
indicate that maximum sustained winds have increased to near 70 mph
(110 km/h) with higher gusts. Some fluctuations in strength will be
possible during the next 36 hours, but Isaias is expected
to be a strong tropical storm when it reaches the coast of
northern South Carolina and southern North Carolina Monday night.
Slow weakening is forecast after Isaias makes landfall in the
Carolinas and moves across the U.S. mid-Atlantic region late Monday
Tropical-storm-force winds extend outward up to 115 miles (185 km)
from the center. A weather station at Sebastian Inlet, Florida,
recently measured a wind gust of 49 mph (80 km/h).
The minimum central pressure based on reports from the
reconnaissance aircraft is estimated to be 994 mb (29.36 inches).
