At 400 AM CDT (0900 UTC), the center of Post-Tropical Cyclone Beta
was located near latitude 29.5 North, longitude 95.0 West. The
post-tropical cyclone is moving toward the east-northeast near 9 mph

Maximum sustained winds are near 30 mph (45 km/h) with higher gusts.
Slow weakening is forecast during the next 48 hours.

The estimated minimum central pressure is 1007 mb (29.74 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL: For the upper Texas coast, additional rainfall of 3 to 5
inches with isolated storm totals up to 15 inches is expected
through Wednesday afternoon. Significant urban flooding will
continue as well as minor to isolated moderate river flooding. Flash
flooding will remain possible through Wednesday afternoon.

Rainfall totals of 2 to 5 inches are expected east into the Lower
Mississippi Valley, portions of the Tennessee Valley, and the
southern Appalachians through the end of the week. Flash and urban
flooding is possible, as well as isolated minor river flooding on
smaller rivers.

SURF: Swells generated by a combination of Beta and a
stationary front over the northern Gulf of Mexico will continue
from the Upper Coast of Texas to the Western Florida Panhandle
during the next couple of days. These swells are likely to cause
life-threatening surf and rip current conditions. Information on
ongoing coastal flooding can be found in coastal flood products
issued by local National Weather Service offices.
