DISCUSSION AND OUTLOOK
----------------------
At 500 PM EDT (2100 UTC), the center of Tropical Depression Laura
was located near latitude 37.2 North, longitude 88.9 West. The
depression is moving toward the east-northeast near 21 mph (33 km/h)
and this motion is expected to continue through the evening.

Maximum sustained winds are near 30 mph (45 km/h) with higher gusts.
Eventually, the remains of Laura will cross the central
Appalachians Saturday, before becoming absorbed by an approaching
cold front that is forecast to move off the mid-Atlantic coastline
by late Saturday.

The estimated minimum central pressure is 1003 mb (29.62 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL: Additional rainfall of 1 to 3 inches, with maximum
amounts to 5 inches forecast across western and central Kentucky
and Tennessee, and south into northern Alabama and Mississippi.

One to 2 inches, with isolated totals to 4 inches will be
possible over southern Louisiana, Mississippi, and
Alabama.

One to 3 inches possible over the central and southern Appalachians
and the mid-Atlantic states through Saturday.

This rainfall will continue to cause isolated flash and urban
flooding, and small streams and creeks to overflow their banks
across the aforementioned regions. Minor to moderate river flooding
is occurring or forecast in Louisiana, Arkansas, and northern
Mississippi.

WIND:  Gusty winds will accompany the tropical depression as it
moves along the Lower Ohio Valley through tonight.

TORNADOES:  A few tornadoes remain possible, mainly over parts of
Mississippi, Alabama, and Tennessee. The risk for a couple
of tornadoes should redevelop Saturday afternoon and evening over
parts of the mid-Atlantic from Virginia to North Carolina.
