Instruction: 
Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles. Even 6 inches of fast-moving flood water can knock you off your feet and a depth of 2 feet will float your car. Never try to walk, swim, or drive through such swift water. If you come upon flood waters, stop, turn around and go another way. Be especially cautious at night when it is harder to recognize the dangers of flooding. Flooding is occurring or is imminent. Most flood related deaths occur in automobiles. Do not attempt to cross water covered bridges, dips, or low water crossings. Never try to cross a flowing stream, even a small one, on foot. To escape rising water find another route over higher ground. Additional information is available at www.weather.gov. The next statement will be issued this evening by 745 PM CDT.
