DISCUSSION AND OUTLOOK
----------------------
At 500 AM EDT (0900 UTC), the center of Post-Tropical Cyclone Laura
was located near latitude 38.4 North, longitude 83.3 West. The
post-tropical cyclone is moving toward the east near 28 mph (44
km/h) and this motion is expected to accelerate further today
and Sunday.

Maximum sustained winds are near 25 mph (35 km/h) with higher gusts.
Some strengthening is forecast during the next 48 hours as it 
emerges into the northwest Atlantic.  On Monday, the system should 
be absorbed into a stronger low moving through Atlantic Canada.

The estimated minimum central pressure is 1004 mb (29.65 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL: Additional rainfall of 1 to 2 inches is forecast across
eastern portions of the Mid-Atlantic states today.

This rainfall may 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:  Winds with Laura are expected to increase near and
offshore the Mid-Atlantic coast as the low pressure system moves
into the northwest Atlantic tonight and Sunday.

TORNADOES:  The risk for a couple of tornadoes should redevelop
Saturday afternoon and evening from North Carolina through the 
Delmarva region.
