Friday is a First Alert Weather Day. The forecast continues show an increased risk for heavy rain, strong gusty winds and tornadoes across the Tennessee Valley beginning Friday afternoon and continuing into Friday night.
Laura has become a violent and very large hurricane. It is a Category 4 storm with winds of 150 mph. Overnight, Laura will bring life threatening storm surge of up to 20′ in some coastal areas of southeast Texas and southwest Louisiana. The storm will make landfall late tonight and continue tracking north through Louisiana and Arkansas into Thursday afternoon. Widespread wind damage is expect for many areas of Louisiana and Arkansas through tomorrow afternoon as Hurricane Laura slowly weakens as it tracks farther north. By Friday morning the large storm will begin to make a sharp right turn northwest of Memphis, TN and head east. By late Friday afternoon we expect bands of showers and storms associated with Laura to being moving across north Alabama and middle Tennessee. A threat severe weather will develop in west Alabama first and track east into the evening. The storms will be capable of localized flash flooding, isolated damaging wind gusts and quick spin-up tornadoes. Any tornadoes that form should be brief and on the lower end of the enhanced Fujita scale (EF0—EF1). Keep checking back for updates regarding the track and threat from Hurricane Laura. When dealing with landfalling tropical systems there can often be surprises along the way so be sure to stay informed through our First Alert Weather App as well.
Ahead of all this mess we expect a very hot and muggy day on Thursday with highs around 90. The heat index will be around 103. A few isolated showers and storms can’t be ruled out. We will start the day Friday on the dry side with the storm chances increasing after 1pm. It looks like Laura should be out of the Tennessee Valley by Noon Saturday but there will still be a front in the area. Scattered storms could return Saturday afternoon with isolated storms Sunday. Highs near 90 this weekend.
Have a great night.
