Know how flash flooding happens here
Flash floods are sudden floods that develop quickly, often from intense rain over a short period. In the Las Vegas Valley, runoff can concentrate in washes, low streets and dips in roadways. Rain falling miles away can also send water into channels that run through populated areas.
The Clark County Regional Flood Control District plans and builds flood control facilities across the county and publishes flood information for residents. The National Weather Service in Las Vegas issues watches and warnings for the valley.
Stay safe during a flood
Most flood deaths involve people who drive or walk into water they thought they could cross. Moving water is powerful, and water that looks shallow can hide a deep channel or a washed-out roadway.
- Turn around, don’t drown: never drive or walk through flood water.
- Six inches of fast-moving water can knock an adult off their feet.
- About a foot of moving water can carry away most passenger vehicles.
- Move to higher ground and stay away from washes, drainage channels and underpasses during heavy rain.
- Keep your phone charged and enable emergency alerts.
Protect your home before storms
Simple preparation can reduce the chance of water entering the home. Focus on the entry points where storm water is most likely to come in, such as garage doors, side gates and low doorways. Check that gutters and downspouts discharge away from the foundation, and keep drains and yard inlets clear of debris.
Know where your main water shutoff and electrical panel are, and keep important documents in a safe, dry place.
After the water recedes
Floodwater can carry contaminants, sediment and debris. Avoid contact where possible, and wash your hands thoroughly if you touch it. Stay out of any area where the electrical system may be wet, and do not use appliances that have been in water until a qualified professional has checked them.
Photograph the damage before cleanup, contact your insurer, and consider calling a water damage expert to assess moisture in walls, floors and insulation. Our guide to flood cleanup explains that process in more detail.
