DISCUSSION AND OUTLOOK
----------------------
At 1000 AM CDT (1500 UTC), the center of Tropical Depression Laura
was located near latitude 36.6 North, longitude 90.5 West. The
depression is moving toward the east-northeast near 20 mph (31 km/h)
and this motion is expected to continue as Laura tracks along
and south of the Ohio Valley through tonight.

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 1001 mb (29.56 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL: Expect 1 to 3 inches, with isolated 5 inch totals from
western and central Kentucky and Tennessee into northern Alabama
and Mississippi. One to 2 inches, with isolated 4 inch totals
are possible over southern parts of Louisiana, Mississippi, and
Alabama. By Saturday, 1 to 3 inches of rain is forecast from the
central and southern Appalachians to the mid-Atlantic states.

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

WIND:  Gusty winds of 25-30 mph will accompany Laura’s circulation
as it moves toward the Lower Ohio Valley through the afternoon.
Stronger gusts are possible within thunderstorms.

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