Wendell, ID Hail Storm – September 2025

Wendell, ID saw a concluded hail event on September 21, 2025, with peak hail of 1 inch. The storm moved through the single-zone report area in the afternoon.

What Happened

The severe thunderstorm alert for Wendell was issued at 2:29 PM MDT and carried a 1-inch hail threat. Dual-polarization radar detection supported the alert with NEXRAD hail confidence. The event later concluded and no additional hail alerts were listed for this storm.

The timing puts the hail threat in the mid-afternoon window for the Wendell metro area. The report set remained limited to one alert, which kept the event narrow in scope. The mapped warning area covered the general storm path, while the radar detection pointed to a localized hail core within that area.

Damage Assessment

One-inch hail reaches a size that can damage roof shingles, dent softer metal surfaces, crack older skylights, and leave marks on vehicle panels. The risk rises on aging roofs, thin gauge siding, and exposed equipment stored outdoors. Newer roofing systems can still show impact marks, but the visible damage may be scattered rather than uniform.

Field crews should expect the highest concentration of impacts where the hail core passed directly over roofs, canopies, and parking areas. On a single-zone event like this, damage can change quickly from one block to the next. A house or commercial lot just outside the core may show little or no impact while nearby structures carry visible strike patterns on upward-facing surfaces.

For claims work, look first at asphalt shingles, vents, ridge caps, gutters, window screens, and HVAC housings. Vehicles parked in the open during the alert window may show panel dents, mirror damage, or glass chips. Agricultural and industrial properties should be checked for punctures in plastics, membrane roofs, and thin metal covers.

What Contractors Should Know

Start with the roof slope and the exterior faces that took direct exposure during the afternoon window. One-inch hail can produce a mixed damage picture. Soft metals and aged shingles may show clear strikes, while harder surfaces show only scattered marks. Crews should document slope direction, impact density, and the difference between upper and lower elevations on the same property.

Keep inspections localized to the hail path rather than treating the full Wendell area as uniformly hit. The alert area was broad enough to cover the storm’s general path, but the radar-derived hail point set was more focused. That means a quick windshield survey can miss the strongest impacts if crews stay too far from the core line.

Contractors working estimates should separate cosmetic marks from functional loss. Look for bruised shingles, displaced granules, cracked sealant, bent soft metals, and broken attachments around rooftop equipment. On commercial sites, pay close attention to parapet flashing, roof penetrations, and exposed condensers. Photograph the slope, the strike marks, and the surrounding roof planes before any temporary repair work begins.
