What Is Driving the Storms?
Several upper-level disturbances are moving through the region, helping trigger scattered showers and thunderstorms.
The Alabama Emergency Management Agency is also warning of multiple rounds of showers and thunderstorms across Alabama through Friday. Some of the stronger storms could produce 40–60 mph wind gusts, torrential rainfall, and localized flooding. (Alabama Emergency Management Agency)
As storms develop and move along boundaries, individual cells can strengthen quickly. Therefore, conditions can change considerably within a short period of time.
Main Threats This Afternoon
Damaging Wind Gusts
Strong thunderstorm wind gusts are the primary concern highlighted with the current Tennessee storms. Gusts around 50 mph can break branches, damage unsecured outdoor items, and cause isolated power disruptions.
Frequent Lightning
Lightning remains a significant danger even when rainfall is not particularly heavy. The National Weather Service advises people outdoors to move inside a substantial building or vehicle when thunderstorms approach. (National Weather Service)
Heavy Rainfall
Some thunderstorms may produce torrential rainfall over a short period. Poor drainage areas, low-lying roads, and locations that repeatedly receive thunderstorms could experience localized water problems.
Hail
While the primary concern is strong wind, hail can occur within stronger thunderstorm cores.
Safety Tips for Residents
If a Severe Thunderstorm Warning is issued for your county, move indoors immediately. Stay away from windows and monitor the warning for updates.
During thunderstorms:
- Move inside a sturdy building.
- Stay away from windows and exterior doors.
- Avoid unnecessary travel through the strongest storms.
- Never drive through flooded roadways.
- Unplug sensitive electronics if severe weather approaches.
- Bring loose outdoor objects inside when possible.
- Stay indoors until the storm has passed.
- Continue monitoring warnings even after the first storm moves away.
For motorists, heavy rain can quickly reduce visibility and create dangerous hydroplaning conditions. Slow down and give thunderstorms plenty of room.
Counties to Watch
Mississippi: Tishomingo County, Alcorn County.
