What the agency told people to do
Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles. Be aware of your surroundings and do not drive on flooded roads. Remain alert for flooding even in locations not receiving rain. Washes, streams, and rivers can become raging killer currents in a matter of minutes, even from distant rainfall.
