DISCUSSION AND OUTLOOK
----------------------
At 500 PM EDT (2100 UTC), the center of Tropical Storm Debby was
located near latitude 32.5 North, longitude 79.1 West. Debby is
moving toward the north-northeast near 3 mph (6 km/h). A turn toward
the north is expected tonight, bringing the center across the South
Carolina coast on Thursday morning. After landfall, 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.
Slight strengthening is possible 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. NOAA buoy 41013 at Frying Pan Shoals recently
reported a wind gust of 40 mph (65 km/h).

The estimated minimum central pressure based on NOAA buoy data 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 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 eastern South Carolina and 15
inches in southeast North Carolina with considerable flooding
expected 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
rainfall observations (and wind reports) associated this storm, see
the companion storm summary at WBCSCCNS4 with the WMO header ACUS44
KWBC or at the following link:

TORNADOES: A few tornadoes may occur over parts of eastern North
Carolina and extreme eastern South Carolina through tonight. The
risk of tornadoes will shift northward on Thursday into central
North Carolina and central Virginia.

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.
