Crosby, ND Hail Storm – June 2026

Crosby, ND experienced large hail during the evening of June 6, 2026, producing a multi-zone severe hail event with a peak 2.98-inch stone. The storm produced five consecutive NWS warning-area alerts across late evening and into early morning.

What Happened

The first NWS warning-area alert for this event issued at 8:15 PM CDT on June 6 and reported 1.5-inch hail. Subsequent alerts issued at 10:35 PM CDT (1.25-inch), 10:41 PM CDT (1.0-inch), 11:29 PM CDT (1.0-inch), and 12:02 AM CDT on June 7 (1.0-inch). All five alerts are recorded as NWS warning only confidence for the warning areas listed.

Warnings tracked a northeast progression through the Crosby metro area. Observational data indicate a concentrated hail swath within the broader warning areas. Field reports and post-event mapping show larger stones localized along that swath. Radar signatures supported hail detection during the warning period, while the NWS warnings provided public alerting across multiple adjacent notification zones.

The event is concluded. No additional warnings remain active for this storm system in the Crosby area.

Damage Assessment

Warnings in this sequence covered hail sizes commonly associated with cosmetic and soft-surface damage for most exposed assets in the warning area. Repeated 1.0–1.5-inch reports increase the likelihood of shingle granule loss, denting to steel and aluminum surfaces, and localized landscaping damage where turf and siding were exposed.

Larger stones concentrated along the mapped hail swath increase risk to unprotected vehicles, rooftop shingles, skylights, and vinyl siding. Where larger stones struck treated roofing or older shingle installations, expect accelerated granular wear and elevated shingle tear rates. Glass breakage is possible where impact points coincide with structural vulnerabilities such as older window units or existing cracks.

Document all damage with geotagged photos and time-stamped notes during inspections. Prioritize safety around broken glass and roof access; secure tarps and coverings only where conditions and training allow safe work.

What Contractors Should Know

Begin with a rapid exterior triage for life-safety hazards and major water entry points. Inspect accessible roofing areas for granule loss, split or curled shingles, and exposed underlayment. Check vehicles, HVAC condenser fins, solar panels, and exposed signage for impact dents. Record item-level observations with GPS coordinates and clear scale references in each image.

Prepare scope estimates that separate cosmetic from functional damage. Note that repeated smaller impacts across a large surface can produce materially different repair needs than isolated larger impacts. Use temporary measures—tarps, board-up, or cordoning—only where they reduce immediate risk of further damage or injury. Coordinate documentation with insurers and maintain a chain of custody for all field photos and reports.
