WATCHES AND WARNINGS

DISCUSSION AND OUTLOOK
----------------------
At 1000 AM CDT (1500 UTC), the center of Post-Tropical Cyclone Delta
was located near latitude 35.2 North, longitude 86.5 West. The
post-tropical cyclone is moving toward the northeast near 16 mph (26
km/h) and this motion is expected to continue into Monday morning.

Maximum sustained winds are near 25 mph (35 km/h) with higher gusts.
Additional weakening is expected into Monday morning, when
dissipation of the center is expected as a new low develops east of
the Appalachians.

The estimated minimum central pressure is 1005 mb (29.68 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL: In the Appalachian region of northeast Georgia, the
western Carolinas, and western Virginia, the remnants of Delta
are expected to produce storm total rainfall of 3 to 6 inches.
These rainfall amounts have already led to flash, urban, and
small stream flooding along with isolated minor to moderate
river flooding for parts of the region, and the flood
threat, especially in areas of steep terrain, will continue
through today.

Across much of the rest of the Mid-Atlantic, 1 to 3 inches of rain,
with locally higher amounts, are expected. Localized flash and
urban flooding are possible, but overall hydrologic impacts
are expected to be minimal.

Moderate to major river flooring will continue across the
Calcasieu and Mermentau river basins in Louisiana through much
of next week.

TORNADOES: A few brief/weak tornadoes are possible across the
Carolinas today.


NEXT ADVISORY
-------------
Next complete advisory at 400 PM CDT.
