Important Safety Reminders During Flash Flooding

Published on July 23, 2025

A flash flood warning has been issued in Sioux Falls. Remember these important reminders:

• Flash flooding can occur anywhere, so please use caution when driving.
• Do not drive into flooded intersections. There may be debris on the road or under the water that a driver cannot see, and even a small amount of moving water can carry a vehicle off the road. Driving through flooded areas can cause extensive damage to your car and could be a danger to anyone inside the car.
• Watch for manhole covers that may be missing from roadways. When the storm drainage system becomes pressurized because of high flows, some manhole covers may move or lift off.

Report a flooded intersection or missing manhole cover through the City of Sioux Falls App.
