Rare storm pelts Phoenix with golf ball-sized hail

Analysis

Why This Matters

Hail of this size is rare in Phoenix and can cause significant property damage to homes, windows and vehicles in a short period.
The storm system carried a wider threat across Arizona, with tornado watches signalling danger beyond the hail itself.
Residents caught in the open, including those sheltering in cars, faced immediate safety risks as windows gave way.

Background

Phoenix sits in the Sonoran Desert, where severe thunderstorms are most common during the summer monsoon season and damaging hail is uncommon. Hail forms when strong thunderstorm updrafts carry water droplets high into freezing air, and stones the size of golf balls are large enough to break glass and dent roofs.

Key Perspectives

Residents: Caught in the storm, many sought shelter inside cars and buildings as hail broke through glass and intense downpours covered neighbourhoods in ice.

National Weather Service: Forecasters issued multiple warnings and tornado watches to give people advance notice as the storms tracked across the region.

Homeowners and drivers: With homes damaged and windows shattered, residents face repair costs and likely insurance claims in the storm's aftermath.
