The National Weather Service (NWS) predicts more rain for our area, including flash floods, severe thunderstorms and possible tornadoes. Flooding concerns have led to many local school closures.
Heavy rainfall is expected Friday. Strong to severe storms will be possible Saturday afternoon and evening. Damaging straight-line winds and a couple tornadoes will be the main threat with these storms.
Flash Flood Watch
NWS has issued a Flash Flood Watch in effect for many areas of Middle Tennessee including Williamson County. The watch is in effect until Saturday evening.
What is a Flash Flood Watch?
A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation.
NWS says potentially life-threatening flooding will be possible, especially early Friday morning through Friday night. They advise those who live southwest portions of Middle TN, including those west of I-24 and south of I-40 need to have a plan in place now in case the need arises to evacuate to higher ground.

What to do in the Event of Flooding
During a flood, water levels and the rate the water is flowing can quickly change. NWS gives the following advice on what to do in the event of a flood.
- Stay Informed: Listen to radio and television, including NOAA Weather Radio if possible, check the Internet and social media for information and updates.
- Get to Higher Ground: If you live in a flood prone area or are camping in a low lying area, get to higher ground immediately.
- Obey Evacuation Orders: If told to evacuate, do so immediately. Lock your home when you leave. If you have time, disconnect utilities and appliances.
- Practice Electrical Safety: Don’t go into a basement, or any room, if water covers the electrical outlets or if cords are submerged. If you see sparks or hear buzzing, crackling, snapping or popping noises–get out! Stay out of water that may have electricity in it!
- Avoid Flood Waters: Don’t walk through flood waters. It only takes 6 inches of moving water to knock you off your feet. If you are trapped by moving water, move to the highest possible point and call 911 if possible. Do NOT drive into flooded roadways or around a barricade; Turn Around, Don’t Drown! Water may be deeper than it appears and can hide hazards such as sharp objects, washed out road surfaces, electrical wires, chemicals, etc. A vehicle caught in swiftly moving water can be swept away in seconds 12 inches of water can float a car or small SUV, 18 inches of water can carry away large vehicles.
