1. Additional rainfall will continue to lead to flash flooding along small streams, urban areas, roadways, and minor to moderate river flooding across portions of Louisiana, Mississippi and Arkansas. The heavy rainfall threat and flash and urban flooding potential will spread northeastward into the middle-Mississippi, lower Ohio and Tennessee Valleys, and Mid-Atlantic States Friday and Saturday.

2. A few tornadoes remain possible this evening across eastern Arkansas, western Tennessee, northern Mississippi, and the Missouri Bootheel. The risk for a few tornadoes is expected to redevelop Friday afternoon into the evening across parts of the Mid-South and Tennessee Valley regions.

There are no coastal watches or warnings in effect.

Key messages for Laura can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC.

RAINFALL: Through Friday, Laura is expected to produce the following additional rainfall totals: Over central and northern Arkansas: Additional 3 to 6 inches. Over southern Louisiana and southern Mississippi: 1 to 3 inches, with isolated additional totals of 5 inches. Over northern Mississippi, western Tennessee, and southcentral to southeast Missouri: 1 to 3 inches, with isolated totals of 5 inches. This rainfall will continue to cause widespread flash and urban flooding, small streams and creeks to overflow their banks, and minor to moderate freshwater river flooding. Through Saturday, Laura is expected to produce 1 to 3 inches with isolated maximum amounts of 5 inches across portions of the Tennessee and Lower Ohio Valleys, the central and southern Appalachians, and the MidAtlantic States. This rainfall may lead to flash and urban flooding and rapid rises on small streams. TORNADOES: A few tornadoes remain possible this evening across eastern Arkansas, western Tennessee, northern Mississippi, and the Missouri Bootheel. The risk for a few tornadoes is expected to redevelop Friday afternoon into the evening across parts of the MidSouth and Tennessee Valley regions.

SURF: Swells produced by Laura continue to affect the U.S. Gulf coast from the Florida Panhandle to Texas. These swells are likely to cause lifethreatening surf and rip current conditions. Please consult products from your local weather office.

At 1000 PM CDT (0300 UTC), the center of Tropical Depression Laura was located near latitude 35.1 North, longitude 92.0 West. The depression is moving toward the northnortheast near 15 mph (24 km/h), and this general motion should continue overnight. A northeastward to eastnortheastward motion is expected to begin on Friday and continue into Saturday. On the forecast track, the center of Laura is forecast to move over Arkansas tonight, the midMississippi Valley on Friday, the midAtlantic states on Saturday, and over the western Atlantic on Sunday. Maximum sustained winds have decreased to near 35 mph (55 km/h) with higher gusts. Laura is expected to become a remnant low pressure system on Saturday, and an extratropical low later this weekend.

The estimated minimum central pressure is 993 mb (29.33 inches).

Laura has continued to spin down after being over land for nearly a day. Surface observations no longer support tropical storm intensity, and therefore the system is being downgraded to a tropical depression. The cyclone should become a post-tropical low within a couple of days, and then transform into an extratropical cyclone while moving off the U.S. east coast. The official forecast shows some restrengthening in 2-4 days due to baroclinic processes. However, by the end of the forecast period, the system should be absorbed by a larger extratropical cyclone to the east of the Canadian Maritimes.Laura continues to move north-northeastward or at about 015/13 kt. A turn toward the northeast and east-northeast with increasing forward speed is likely while the cyclone becomes embedded in the stronger westerly flow. The official track forecast follows the latest dynamical model consensus.There is a continued threat of flooding from Laura for the next couple of days. This is the last NHC advisory on Laura. Future information on this system, including the rainfall threat, can be found in Public Advisories issued by the Weather Prediction Center beginning at 4 AM CDT, under AWIPS header TCPAT3, WMO header WTNT33 KWNH, and on the web at http://www.wpc.ncep.noaa.gov
