DISCUSSION AND OUTLOOK
----------------------
At 800 AM EDT (1200 UTC), the center of Hurricane Imelda was located
by an Air Force Hurricane Hunter aircraft near latitude 29.0 North,
longitude 76.9 West. Imelda is moving toward the northeast near 7
mph (11 km/h). This general motion is expected through today,
followed by a turn towards the east-northeast at a faster forward
speed by tonight. On the forecast track, the center of the system
should move away from the Bahamas today and quickly be approaching
Bermuda late on Wednesday.

Maximum sustained winds have increased to near 75 mph (120 km/h)
with higher gusts. Some additional strengthening is forecast
during the next 48 hours.

Hurricane-force winds extend outward up to 70 miles (110 km) from
the center and tropical-storm-force winds extend outward up to 185
miles (295 km).

The estimated minimum central pressure is 980 mb (28.94 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Storm Imelda can be found in the Tropical
Cyclone Discussion under AWIPS header MIATCDAT4 and WMO header
WTNT44 KNHC.

WIND: Hurricane conditions are possible within the watch area by
Wednesday night, with tropical storm conditions possible by
Wednesday afternoon.

RAINFALL: Storm total rainfall amounts of 1 to 2 inches with local
maxima of 4 inches are expected through tonight across coastal
sections of southeast North Carolina. This rainfall could result in
isolated flash and urban flooding.

As Imelda passes near Bermuda, 2 to 4 inches - 50 to 100 mm - of
rainfall is expected from Wednesday into Thursday.

STORM SURGE: Minor coastal flooding is possible in areas of onshore
winds over the Southeastern U.S. coastline. The water could reach
the following heights above ground somewhere in the indicated areas
if the surge occurs over the next several high tide cycles...

Volusia/Brevard County Line, Florida to the South Santee River,
South Carolina...1 to 2 ft

SURF: Swells generated by Hurricane Imelda and Hurricane Humberto
are affecting the Bahamas and are currently spreading to much of the
U.S. east coast. These swells are likely to cause life-threatening
surf and rip current conditions. Please consult products from your
local weather office.
