DISCUSSION AND OUTLOOK
----------------------
At 400 AM CDT (0900 UTC), the center of Post-Tropical Cyclone Delta
was located near latitude 34.6 North, longitude 87.7 West. The
post-tropical cyclone is moving toward the east-northeast near 15
mph (24 km/h) and this motion is expected to continue today.

Maximum sustained winds are near 30 mph (45 km/h) with higher gusts.
Weakening is forecast during the next 24 hours, as Delta`s
surface low is expected to dissipate across the central
Appalachians late Sunday night.

The estimated minimum central pressure is 1004 mb (29.65 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, which
could lead to flash, urban, and small stream flooding, especially in
areas of steep terrain. Isolated minor river flooding is possible.

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 Vermillion river basins in Louisiana through much of next week.


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