WASHINGTON — Flash flooding has been rampant across the United States since the spring, and it continued over the weekend in several states from the Southeast to the Mountain West.

Two men in a vehicle got caught up in a flash flood Saturday evening in Bonne Terre, Mo., south of St. Louis. As much as 4 inches of rain had fallen in the area, causing several streams and creeks to overflow.

When emergency officials arrived, the car was already downstream. One man had already made it to dry land, but the other was still in the water, hanging on to a tree branch for at least an hour.

Nine miles southeast, first responders rescued a woman who drove into the flood and was locked in her car after water shorted the vehicle’s electronics.

In Georgia, flash flooding prompted officials to evacuate an apartment complex in Jonesboro, a suburb of Atlanta, Saturday.

In Colorado, torrential rain caused landslides and road closures when a creek west of Pueblo overflowed.

In the Flagstaff, Ariz., area, flooding was bad enough on Sunday that the American Red Cross opened a shelter at a middle school for families affected.
