Dates: October 10–12, 2025
Moisture from the remnants of former Tropical Storm Priscilla is teaming up with a fall storm to bring widespread, soaking rains to northern Arizona. The setup could produce periods of heavy rainfall and dangerous flash flooding, especially from late Friday into Saturday. Flood watches and flood‑risk outlooks are in effect across parts of Arizona and may change as the event unfolds. Check NWS Flagstaff for the latest local alerts and timing.
Before the rain: prepare now

During the flooding: safety first
Turn Around, Don’t Drown

Do not walk through moving water. Six inches can knock a person down.
Keep away from washes, streams, and drainage channels—even when they look low.
Respect barricades. They’re placed where danger is known.
If caught in rising water
Get to higher ground immediately
Abandon a vehicle if water is rising around it or it begins to float
Stay away from power lines and electrical equipment
Call 911 if you’re in immediate danger
Driving tips
Avoid non‑essential travel during peak rainfall periods (late Friday through Saturday)
If you must drive, slow down, increase following distance, and use extra caution at night
Watch for debris, undercut pavement, and sinkholes
