Parker, AZ Hail Storm – October 2025

What Happened

A severe hail storm crossed the Parker, AZ metro on October 13, 2025, with the peak hail size reaching 2 inches and multiple alert cycles through the day. The first hail call came at 8:52 AM MST with 1-inch hail from dual-polarization radar, followed by a 9:26 AM MST alert that carried radar and spotter verification.

The storm rebuilt through midday. Alerts at 12:49 PM MST and 1:30 PM MST again called for 1-inch hail on dual-polarization radar, and a 2:19 PM MST warning kept the hail threat in place on warning-area guidance alone. Another 1-inch hail alert came at 4:57 PM MST, also from dual-polarization radar, before the storm’s strongest hail report arrived at 5:49 PM MST with a 2-inch spotter report.

Field reports lined up with that late-day escalation. At 5:55 PM MST, a spotter confirmed 2-inch diameter hail. Earlier, at 1:15 PM MST, a report of quarter-sized hail placed 1-inch hail in the middle of the event cycle. The sequence shows a storm that stayed active for most of the day and renewed its hail threat several times before the largest stones were reported.

Damage Assessment

The field reports point to a broader severe-weather day than hail alone. The report set includes tree damage, roof loss, vehicle impacts, and flooding notes across the region, with several reports clustered around the Phoenix metro and nearby corridors during the afternoon. In Parker and surrounding areas, the confirmed hail reports were paired with storm impacts that fit a long-lived convective system rather than a short, isolated burst.

The most direct hail impact came from the 2-inch spotter report near the end of the event. Before that, a quarter-sized hail report at 1:15 PM MST confirmed smaller stones during the active afternoon phase. The timing places hail on the ground in more than one pulse, not just one brief burst.

Other spotter reports show how far the storm’s effects reached. Around 10:15 AM MST, social media images showed flash flooding along Parker Dam Road in Earp, CA. At 1:10 PM MST, the Phoenix Zoo reported about 12 trees and 2 light displays blown over, leading to a closure. At 1:15 PM MST, multiple reports described downed trees, roof damage, torn-off roof sections at a mobile home park, and a complex with severe tree fall that damaged apartments and trapped people inside. Several reports also mentioned uprooted trees blocking roads, including areas near Rural Road and Guadalupe Road and near 56th Street and Dublin Lane.

The damage pattern also included broken trees, powerline impacts, and debris thrown across streets. One report at 1:38 PM MST described palo verde trees snapped in half and a metal shed blown onto 56th Street. Another at 1:50 PM MST noted Indian Bend going above alarm stage near Shea Boulevard with flooding on the greenbelt and low-water crossings downstream. These reports show a storm day with wind and water impacts layered onto the hail threat.
