A slow-moving weather system will bring the risk of a few severe storms and flooding rainfall to the Southeast states into Sunday evening. Damaging wind gusts and hail will be the main threats, though a couple tornadoes cannot be ruled out.

This same storm system brought severe weather and heavy rain to the South on Saturday.

One tornado was observed Saturday afternoon near Burton and Belmont in northeastern Mississippi, and this radar- and public-confirmed tornado continued into Franklin County, Alabama. Debris fell out of the sky in Franklin County, Alabama, and damage was reported at the Shiloh Baptist Church.

Localized flooding was reported south of Nashville, including in Nolensville, Brentwood and Franklin, Tennessee, as heavy rain moved through the area Saturday morning. By Saturday afternoon, flash flooding was also occurring in Wilson and Williamson counties, Tennessee, and at least one water rescue was necessary.

Just west of Knoxville, Tennessee, near Oakdale, portions of State Highway 328 were shut down Saturday evening, due to flooding and a rockslide that occurred on Highway 62.

Heavy rainfall caused minor flooding in eastern Tennessee, including Knoxville, and several people reported golf ball-size hail.

Current Radar, Watches and Warnings

Below is our latest forecast thinking on the timing and magnitude of the severe threats through Sunday evening.

Severe Weather Forecast

Sunday Evening

  • Forecast: The risk of a few severe thunderstorms will slide east into parts of the Southeast, mainly from South Carolina southward into Georgia and northern Florida.
  • Threats: Damaging wind gusts and large hail will be the primary concerns, although a couple tornadoes cannot be ruled out, particularly after dark.
  • Locally heavy rain is also likely in the Appalachians and adjacent piedmont, with a threat of flash flooding. See below for more information.
  • Cities: Charleston, South Carolina | Savannah, Georgia | Tallahassee, Florida

Heavy Rainfall Expected

As mentioned above, flash flooding is also a concern with this round of severe storms. Flood watches have been issued for eastern parts of Tennessee and Kentucky to portions of southwest Virginia, North Carolina and South Carolina where multiple rounds of locally heavy rain could create flooding into early this week.

An expansive swath of at least 3 inches of rain is expected in the southern Appalachians and adjacent piedmont through Monday.

Keep this is in mind if you're traveling. Never drive through floodwaters of unknown depth, as roughly two-thirds of flash flood fatalities occur in vehicles.

Half of the village of Big Sur, on the coast of central California, has lost its only access to the north following the demolition of the flood-damaged Pfeiffer Canyon Bridge along State Route 1 (also Rt. 1 or SR 1) on March 19. Although Rt. 1 to the south of Big Sur has reopened to traffic (after mud and rock slides were cleared) it is a long 70-mile journey along the windy but spectacular highway to Cambria, the next town of any significance where supplies can be had. CalTrans (California Department of Transportation) estimates it will take 6-9 months to rebuild a new bridge over the canyon.

By now, many of you have heard or read about the arrest of Ahmed Mohamed, a 14-year-old high school student from Irving, Texas. Ahmed was arrested because school officials called the police after he showed one of his teachers his homemade clock. Mistaken for a bomb, Ahmed was taken into custody, interrogated, shamed, suspended (still on suspension today, Wednesday), and reprimanded. All of this after it has been found that the "device" he brought to school was indeed, a homemade clock.
