What to do
Do not drive into flooded roads. The National Weather Service says to turn around, don't drown, because most flood deaths occur in vehicles. Find an alternate route.
In hilly terrain there are many low water crossings that can be dangerous in heavy rain. Do not try to cross them when water is covering the road.
Move to higher ground if water is rising near you. Never drive around barricades. Just 6 inches of moving water can knock you down, and 1 foot of moving water can sweep a vehicle away.
Check for updates from the National Weather Service in Phoenix until the warning ends at 10:30 AM MST.
Context
FEMA flood-insurance claims count only insured properties, so they understate total flood losses. Maricopa County has 2,643 claims from 1978 to 2026. Gila County has 155 claims from 1980 to 2025.
FEMA records show past disaster declarations for flooding in both counties. Gila County had declarations in 2006 and 2010 for severe storms and flooding. Maricopa County had one in 2014 for severe storms and flooding.
