Overview
- The National Weather Service confirmed a microburst struck Tempe during Monday’s supercell, producing straight-line winds and ruling out a tornado.
- Winds were widely near 70 mph with local peaks of 80–90 mph, and rapid downpours delivered about three‑quarters of an inch at ASU in roughly 15 minutes.
- Power outages climbed into the tens of thousands at the peak, with reports up to about 34,000 customers, and most service has been restored with some still without power.
- Tempe opened the Escalante Multi‑Generational Center for displaced residents and partnered with the Arizona Humane Society to assist with pets.
- City, county and utility crews are assessing damage, removing debris and urging residents to report losses to support funding and assistance requests.
