Arizona Weekend Weather Alert: Flash Flood Risk for Tucson and I-10 Through Saturday
TUCSON, Ariz. — A Flood Watch remains in effect for much of southern Arizona through Saturday evening, as thunderstorms fueled by Gulf moisture bring heavy rain and dangerous flooding risks.
I-10 Travel and Flood-Prone Areas at Risk
The National Weather Service in Tucson warned that rainfall totals of 1–2 inches could quickly overwhelm low-lying roads and washes.

- Charge devices in case of power outages.
- Secure outdoor items ahead of strong storms.
- Keep travel plans flexible until the weather system clears.
