Severe Monsoon Storms Bring 60 MPH Gusts and Flash‑Flood Warnings to Western and Central Arizona

Overview

• The National Weather Service issued multiple radar‑indicated Severe Thunderstorm and Flash Flood warnings after storms produced wind gusts up to 60 mph over Maricopa and Pinal counties.
• Doppler radar showed localized downpours of about 0.5 to 1.5 inches with additional rain possible, prompting life‑threatening flash‑flood warnings for communities including Lake Havasu City, Topock, Mohave Valley and others.
• Officials warned of frequent cloud‑to‑ground lightning and pea‑size hail and advised people to seek shelter inside a building or vehicle because lightning can strike up to 10 miles from a storm.
• Warnings named vulnerable interstate segments and travel corridors, raising risks of flooded underpasses and dangerous driving on I‑10, I‑8 and I‑40 and advising motorists to 'Turn around, don’t drown.'
• These events reflect typical summer monsoon behavior in Arizona, with short‑lived but intense storms that can cause rapid urban and wash flooding and sudden damage to roofs, siding and trees.
