What to do
Stay out of floodwater. The National Weather Service says low water crossings become dangerous in heavy rain. Do not try to cross a flooded road, and find another route.
Expect washes and creeks to flood. Some dirt roads will turn muddy and impassable, and paved roads and underpasses could flood too. Avoid these areas while the warning is active.
Just 6 inches of moving water can knock you down, and 1 foot of moving water can sweep a vehicle away. Move to higher ground if water is rising near you, and never drive around barricades.
Camping or recreating near creeks, washes or the Verde River? Move away from the water now. Check the National Weather Service for updates until the warning ends.
Context
FEMA flood-insurance claims count only homes and businesses with flood insurance, so they understate total flood damage. Records list 300 claims in Coconino County, 155 in Gila County and 470 in Yavapai County. This shows that flooding has hit all three counties before.
FEMA has also issued federal disaster declarations for storms and flooding here. Coconino County has a flood declaration from 2021 and storm declarations from 2010. Gila and Yavapai counties were both covered by a 2010 declaration for severe winter storms and flooding.
