Storm clouds building over cracked desert ground ahead of a flash flood
A single storm cell over the Catalinas can send a flash flood through a dry wash in under an hour.

Flash flooding is Tucson’s signature monsoon hazard: a storm cell miles away can send a wall of water down a normally-dry wash and into homes and streets within minutes. That water is fast, contaminated, and full of debris — and the cleanup is urgent and specialized.

Never drive or walk into a flooded wash — follow the NWS Turn Around, Don’t Drown® guidance. Most Arizona flood deaths are in vehicles. Deal with property after the water recedes and it’s safe.

Why flash-flood cleanup is different

Flash-flood water is Category 3 (contaminated) and arrives with mud and debris. Soaked porous materials are removed, structural surfaces cleaned and sanitized, then dried to standard. See the Pima County Regional Flood Control District for wash and flood-alert maps.

After the water recedes

Document everything, avoid contaminated water and hidden hazards, and get extraction going fast — the 24–48 hour mold window applies. The NWS Tucson issues flash-flood warnings throughout monsoon season.

Questions homeowners ask

Is flash-flood damage covered by insurance?
Rising-water flooding is excluded from standard homeowners policies (separate flood insurance applies). Some storm damage may be covered — see our coverage guide.
Is the water dangerous?
Yes — flash-flood water is contaminated and carries debris and bacteria. Don’t wade in it; let a crew handle extraction and sanitizing.
How fast should cleanup start?
As soon as it’s safe — contaminated water plus heat and the mold window make delay costly.
