DISCUSSION AND OUTLOOK

At 1000 PM CDT (0300 UTC), the center of Post-Tropical Cyclone
Arthur was located near latitude 29.7 North, longitude 94.5 West.
The post-tropical cyclone is moving toward the northeast near 9 mph
(15 km/h). A northeastward motion at a faster forward speed is
expected tonight, followed by a turn toward the east-northeast
Thursday through Friday. On the forecast track, the remnants of
Arthur should move farther inland over southeastern Texas and
western Louisiana tonight, then cross the southeastern United States
Thursday through Friday.

Maximum sustained winds are near 35 mph (55 km / h) with higher gusts.
While additional weakening is expected as the system moves inland,
the remnants of Arthur will continue to produce widespread heavy
rains across the southeastern United States during the next few
days.

The estimated minimum central pressure based on surface observations
is 1000 mb (29.53 inches).


HAZARDS AFFECTING LAND
--------
Key messages for remnants of Arthur can be found in the Tropical
Cyclone Discussion under AWIPS header MIATCDAT1 and WMO header

RAINFALL: Arthur is expected to produce rainfall totals of 5 to 10
inches, with isolated higher totals near 20 inches, through early
Friday from the Mid and Upper Texas coast east-northeast into
southern and central portions of Louisiana, Mississippi, and
Alabama, along with western portions of Georgia and the Florida
Panhandle. This could generate dangerous to life-threatening flash
flooding.
