DISCUSSION AND OUTLOOK
----------------------
At 1000 PM CDT (0300 UTC), the center of Post-Tropical Cyclone Delta
was located near latitude 34.0 North, longitude 89.5 West. The
post-tropical cyclone is moving toward the east-northeast near 14
mph (22 km/h) and this motion is expected to become more 
east-northeasterly on Sunday.

Maximum sustained winds are near 30 mph (45 km/h) with higher gusts.
Weakening is forecast during the next 24-36 hours, as Delta's 
surface low is expected to dissipate across West Virginia late 
Sunday night.
 
The estimated minimum central pressure is 1002 mb (29.59 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
 
RAINFALL: In the Appalachian region of far northeast Georgia,
the western Carolinas, and western Virginia, the remnants of Delta
are expected to produce 3 to 6 inches of rain, which could lead to
flash, urban, small stream, and isolated minor river flooding.
 
From northern Alabama and the Tennessee Valley into the
Mid-Atlantic, 1 to 3 inches of rain are expected, with locally 
higher amounts expected.  Minimal hydrologic impacts are 
expected.
 
Moderate to major river flooding will continue across the Calcasieu
and Vermilion river basins in Louisiana through much of next week.
 
TORNADOES:  A few tornadoes are possible across eastern 
Alabama, Georgia, and upstate South Carolina tonight.
