What Is a Flash Flood in Arizona
A flash flood is a sudden, rapid flooding of low-lying areas, often within minutes or hours of heavy rain. In Arizona, dry washes, canyons, and urban streets can fill quickly with dangerous water. The National Weather Service issues alerts when rainfall rates suggest flash flooding is likely.
Where and When Flash Floods Happen
Flash floods in Arizona are common during the monsoon season from June through September. They can affect desert valleys, mountain foothills, and cities like Phoenix and Tucson. Burn scars from wildfires increase risk because bare soil absorbs less water and runoff is faster.
How to Stay Safe and Protect Your Property
Monitor local forecasts and heed warnings from the National Weather Service. Avoid driving through flooded roads, and never walk or swim through moving water. Move to higher ground immediately if flooding begins. Keep important documents in waterproof containers and consider flood insurance.
Insurance and Financial Preparedness
Standard homeowners policies usually do not cover flood damage. The National Flood Insurance Program (NFIP) offers policies for renters, homeowners, and businesses in participating communities. Visit the Federal Emergency Management Agency website for more information on coverage and claims.
