What the agency told people to do
Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles. Stay away or be swept away! The banks of creeks and washes are unstable and unsafe during any flooding event. Low water crossings will become dangerous in heavy rain. Do not attempt to cross flooded roads. Find an alternate route.
