Carson, ND Hail Storm – June 2026

A severe hail storm tracked through Carson, ND on June 29, 2026, producing stones to 2.65 inches and prompting multiple NWS warning-area alerts. The event produced spotter-verified tree and structural impacts in the late afternoon.

What Happened

NWS issued nine warning-area alerts for the storm between 2:30 PM CDT and 8:56 PM CDT as the cluster moved across the Carson metro. Dual-polarization radar detected repeated intense cores in the late afternoon. Alerts around 3:07 PM and 3:19 PM CDT flagged the most intense radar returns, followed by additional radar-detected hail signatures through early evening.

Field observers provided direct surface reports within that radar sequence. A trained spotter in Mandan reported hail ranging from 1.5 to 2.0 inches around 3:32 PM CDT and noted numerous 1-inch tree branches down and torrential rainfall. At about 3:38 PM CDT an off-duty NWS employee reported golf-ball size hail and 60 mph gusts, and reported one window on a house broken. Broadcast media relayed photographs of multiple large stones at roughly 4:10 PM and again at 4:55 PM CDT. Later reports show continued, smaller hail into the early evening, including quarter-size hail reported near Hettinger and pea-size hail with heavy rain near Regent around 9:00 PM CDT.

Radar detection and spotter reports overlapped in time and location, producing a multi-zone hail sequence that began in the late afternoon and tapered through the evening. The NWS warning area covered the broader path; spotters provided the ground-truth impact details inside that area.

Damage Assessment

Field reports and media images show the most concentrated surface impacts near Mandan. Trained spotters documented multiple 1-inch limbs down and torrential rainfall in a residential yard. An off-duty NWS employee reported a broken house window associated with golf-ball size stones and strong gusts at roughly 3:38 PM CDT. Photographs relayed through broadcast outlets captured multiple large hailstones consistent with the spotter descriptions.

Reports from Hettinger and Regent show smaller, localized impacts later in the event. Emergency management relayed ongoing quarter-size hail in Hettinger at about 5:04 PM CDT; a final spotter report near Regent at 9:00 PM CDT described pea-size hail with heavy rainfall lasting about 10 minutes. Those later observations correspond with weaker radar cores and the tapering of the storm.

No centralized list of structural claims or vehicle damage was provided in the field reports beyond the single broken window noted above. Damage reports are spatially concentrated along the late afternoon swath near Mandan, with scattered, lower-intensity impacts reported further along the storm track.

What Contractors Should Know

Document and triage in Mandan first. Take dated photographs of broken glazing and exterior impacts at recorded times. The off-duty NWS employee report of a broken window at 3:38 PM CDT establishes a time-stamped point of interior exposure risk; prioritize water‑intrusion mitigation and temporary glazing for homes reporting broken glass. Photograph surrounding tree debris and fallen branches before removal to preserve evidence for claims.
