DISCUSSION AND OUTLOOK
----------------------
At 200 PM EDT (1800 UTC), the center of Tropical Storm Debby was
located near latitude 32.4 North, longitude 79.1 West. Debby has
been drifting northeastward near 3 mph (6 km/h). A generally
northward motion is expected later today, bringing the center to
the South Carolina coast on Thursday morning. After crossing the
coast, a faster motion toward the north and north-northeast across
the Carolinas and the U.S. Mid-Atlantic states is expected on
Thursday and Friday.

Maximum sustained winds are near 60 mph (95 km/h) with higher gusts.
Some strengthening is possible today or tonight before the center of
Debby reaches the coast of South Carolina. Weakening is forecast to
begin on Thursday after the center moves inland. Debby is expected
to merge with a frontal boundary over the U.S. Mid-Atlantic states
on Friday.

Tropical-storm-force winds extend outward up to 185 miles (295 km)
from the center.

The estimated minimum central pressure is 995 mb (29.39 inches).


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

WIND: Tropical storm conditions are expected to continue along the
coast of South Carolina within the tropical storm warning area
through Thursday. Tropical storm conditions are expected
within the tropical storm warning area and possible within the
tropical storm watch area in North Carolina today and continuing
through Thursday.

STORM SURGE: The combination of storm surge and 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...

South Santee River to Ocracoke Inlet including the Neuse and
Pamlico Rivers...1 to 3 ft

For a complete depiction of areas at risk of storm surge inundation,
please see the National Weather Service Peak Storm Surge Graphic,
available at hurricanes.gov/graphics_at4.shtml?peakSurge.

RAINFALL: Debby is expected to produce an additional 3 to 9 inches
of rainfall with locally higher amounts, leading to maximum storm
total amounts as high as 25 inches in South Carolina and 15 inches
in southeast North Carolina, broadening the area of considerable
flooding across portions of South Carolina and southeast North
Carolina through Friday.

An additional 1 to 2 inches of rainfall with locally higher amounts
is possible across southeast Georgia through Thursday, bringing
overall storm total amounts as high as 15 inches, which may
aggravate any ongoing flooding conditions.

From the Piedmont of South Carolina northward across portions of
Virginia, 3 to 7 inches with local amounts to 10 inches, are
expected through Friday. This rainfall will likely result in areas
of considerable flash and urban flooding, with river flooding
possible.

From Maryland north through Upstate New York and Vermont, 2 to 4
inches, with local amounts to 6 inches, are expected through
Saturday morning. This will likely produce considerable flash and
urban flooding as well as river flooding.

For a complete depiction of forecast rainfall and flash flooding
associated with Debby, please see the National Weather Service
Storm Total Rainfall Graphic, available at
hurricanes.gov/graphics_at4.shtml?rainqpf and the Flash Flood Risk
graphic at hurricanes.gov/graphics_at4.shtml?ero. For a list of

the companion storm summary at WBCSCCNS4 with the WMO header ACUS44
KWBC or at the following link:

TORNADOES: A tornado or two may occur over eastern North Carolina
and extreme eastern South Carolina through tonight.

SURF: Large swells will continue to affect the Southeast U.S.
coast through the end of the week. These conditions are likely to
cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
