What to do
Move to higher ground now if you are near Oak Creek, West Fork of Oak Creek, Spring Creek, Dry Creek, or any wash. Stay away from creeks and swimming holes while the warning is active.
Do not drive around barricades or into flooded roads. The National Weather Service says just 6 inches of moving water can knock you down, and 1 foot of moving water can sweep a vehicle away.
Avoid State Route 179 between mile markers 311 and 313 and State Route 89A between mile markers 374 and 393 if you can. Expect muddy dirt roads and possible flooding on paved roads and underpasses.
If you are at a campground or recreation area named in the warning, move to safer ground and keep checking official National Weather Service updates.
Context
The National Weather Service rated the damage threat as considerable. The warning is based on radar indications and reports of a rising creek.
FEMA flood-insurance records show 300 claims in Coconino County and 470 in Yavapai County between 1978 and 2026, as of September 9, 2026. These counts cover only insured properties, so they understate total flood losses. FEMA's most recent flood declaration for Coconino County was in September 2021 for severe storms and flooding.
