Multiple rounds of heavy rainfall will produce widespread flooding over the next several days from Texas to West Virginia.
Threats: Heavy rain and flash flooding
States affected: TX, LA, AR, OK, MS, AL, GA, SC, NC, TN, KY, WV, VA, OH, IN
When: Friday, February 26 - Tuesday, March 2
Recovery efforts in regions hard-hit by the snow and ice storms of the past few weeks will be halted by stormy weather. Multiple rounds of rain are expected starting tonight and continuing into next week, elevating the threat for flash flooding from the Lower Mississippi Valley into the Tennessee Valley.
Rainfall rates of 1”/hour are expected at times, with a bullseye for rainfall totals of 4-8” expected from the Ark-La-Tex region across northern portions of the Deep-South into the Tennessee Valley. Thunderstorms are also possible over the next several days and could produce localized damaging winds and hail.
Much of this rain will fall on locations that received significant snow last week. While all of that snow will have melted prior to the rain, the combination of wet soil and persistent rainfall may lead to localized flooding.
Travel disruptions are likely to occur, mainly in flood-prone areas and during any strong or severe storms that may occur. Additionally, the influx of moisture will cause areas of fog along stretches of I-20, I-40, I-77, I-81, and I-85. Low visibility can lead to multi-vehicle accidents, so transportation agencies may want to consider alternate routes or allocate longer travel time for trucks moving slowly through those regions.
Businesses should review the flood safety section of their emergency plan and ensure that employees are aware of all procedures related to flash flooding. This is also a good time to look at where your assets are located in relation to flood zones and determine any changes needed to your SkyGuard® service. AccuWeather For Business can provide site-specific warnings for varying rainfall amounts and rates that are determined based on geographical location, flood frequency, and site design and material.
