What to do
Do not drive on flooded roads. Low water crossings can become dangerous in heavy rain. If you meet water over the road, turn around and find another route.
Move to higher ground if you are near a creek, stream or normally dry wash. Stay away from these areas while the warning is in effect.
Expect some dirt roads to turn muddy and impassable, and paved roads and underpasses could flood. The warning lists parts of Interstate 40, State Route 260 and State Route 87, among other highways, so check conditions before you travel.
The National Weather Service says just 6 inches of moving water can knock you down, and 1 foot can sweep a vehicle away. Never drive around barricades.
Context
FEMA flood-insurance claims count only insured properties, so they understate total flood damage. Coconino County has 300 claims on record from 1978 to 2026, and Gila County has 155 from 1980 to 2025. Apache County has 10 from 1979 to 2023. The data provided here did not include a count for Navajo County.
Federal disaster declarations for flooding have covered these counties before. Apache and Coconino counties were both part of declaration 4620 for severe storms and flooding on September 13, 2021.
