DISCUSSION AND OUTLOOK ---------------------- At 1000 PM CDT (0300 UTC), the center of Tropical Depression Laura was located near latitude 37.7 North, longitude 86.9 West. The depression is moving toward the east near 24 mph (39 km/h), and this motion is expected to continue through the overnight. 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 overnight, mainly over the Tennessee Valley. The risk for a couple of tornadoes should redevelop Saturday afternoon and evening over parts of the mid-Atlantic from Virginia to North Carolina.
