When a flash flood watch is issued, flash flooding is possible. Remain alert and be ready to evacuate at a moment's notice. A flash flood warning means that flash flooding has been reported. If advised to evacuate, do so right away. Go to higher ground or climb to safety. Try to move to a safe area before access is cut off by flood water. If you are near a river, be aware of water levels. Prepare to move to higher ground if river levels rise. And never cross a body of water in your vehicle. You don't know how deep it is, especially at night. Just two feet of water can sweep you and your car away. Best advice: turn around and you won't drown.
