Never camp on low ground next to mountain streams. Do not cross flooded roadways in vehicles or on foot. It only takes 6 to 12 inches of moving water for most vehicles to become buoyant. Also, the road bed may be washed out under the water. If your vehicle stalls, abandon it immediately, and move to higher ground.
Flooding is most frequent during the evening hours.
Be very cautious after dark when it is more difficult to recognize the flood dangers. Get out of areas subject to flooding, including low spots, canyons, dry washes etc. Do not allow children to play around high water or storm drains.
