Fairmount, ND Hail Storm – August 2025

What Happened

A severe hail storm moved through Fairmount, North Dakota, on Aug. 21, 2025, with spotter-verified hail reaching 1.5 inches in the early evening. Three NWS alerts marked the storm path between 5:26 PM CDT and 7:55 PM CDT, with radar and spotter confirmation on each report.

The first two alerts, issued at 5:26 PM CDT and 5:43 PM CDT, both carried a 1.25-inch hail threat with radar and spotter verification. The final alert at 7:55 PM CDT upgraded to 1.5-inch hail as the storm continued east through the Fairmount area. The sequence shows repeated hail production over more than two hours.

Ground reports came in around 5:29 PM CDT and 5:50 PM CDT. One spotter reported an observed tornado riding the North Dakota and South Dakota state line. Another report described snapped trees and a visible track, with time and location estimated from nearby reports. At 5:50 PM CDT, a Dakota Magic Casino skycam showed a tornado, with the location estimated by radar.

Damage Assessment

The field reports point to more than hail on the ground. They show a storm capable of producing a tornado signature and visible tree damage near Fairmount during the same event window. The snapped trees and track report place surface impacts along the border area south of the town, while the skycam report adds a second confirmed tornado observation later in the evening.

The hail reports were consistent across the event. Radar and spotter verification appeared in all three alerts, and the alert sequence escalated from 1.25-inch hail to 1.5-inch hail by late evening. The reports do not show a single isolated burst. They show a storm that maintained severe hail potential through multiple cycles.

For contractors, the first pass should focus on roof slopes, ridge caps, soft metals, and north- and west-facing elevations in the Fairmount area and along the state line corridor. The combination of repeated hail alerts and tornado-field reports raises the odds of mixed loss types on the same property. Search for bruised shingles, creased tabs, impact marks on vents, and tree-related collateral damage around the same addresses.

Pay close attention to outbuildings, window screens, gutters, downspouts, and vehicle exposure in open lots. A storm with this kind of hail and wind history can leave uneven damage patterns across a short drive radius. One roof may show concentrated impact marks while a nearby structure carries mostly trim, metal, or tree contact damage.

What Contractors Should Know

Use the timing to narrow canvass windows. The first hail alert came at 5:26 PM CDT, and the last came at 7:55 PM CDT. That puts the main inspection window in the late afternoon and early evening, with damage reports arriving in the same span. Teams should prioritize the border area around Fairmount first, then work outward along the storm path.
