What to do
Do not drive into flooded roads. Turn around and find another route. The National Weather Service says most flood deaths occur in vehicles, and just 6 inches of moving water can knock you down.
Know where you are relative to streams, rivers and creeks. They can rise quickly in heavy rain. Move to higher ground if water is rising near you.
Campers and hikers should stay away from streams and creeks in the warned area. Never go around barricades.
The warning runs until 11:15 AM MST. The National Weather Service says up to 1 more inch of rain is possible, so check for updates before heading out.
Context
Flood-insurance claims count only insured properties, so they understate total flood damage. FEMA records show 155 claims in Gila County between 1980 and 2025 and 2,643 in Maricopa County between 1978 and 2026.
Both counties have had federal disaster declarations involving flooding. Gila County had declarations in 2006 and 2010 for severe storms and flooding. Maricopa County had a flood declaration in 2014.
