There are no coastal watches or warnings in effect. 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 Lauras 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. NEXT ADVISORY ------------- Next complete advisory at 400 PM CDT. $$ Carbin |
