Whitwell, TN Hail Storm – September 2026

On September 21, 2026, a thunderstorm tracking through Whitwell, TN produced radar-detected hail up to 1.08 inches and is currently active. The event is producing ongoing convection and localized hail reports across the metro area.

What Happened

The National Weather Service issued an alert for the Whitwell area at 2:55 PM CDT on September 21 based on dual-polarization radar hail detection. The alert flagged hail at the size reported in the lede and included the primary warning polygon covering the affected addresses. Radar returns show the cell continuing to produce strong reflectivity signatures and hail cores as it tracks through the town. Field conditions remain changeable and the storm is still active as of this snapshot.

Damage Assessment

Hail at this size is slightly larger than a U.S. quarter (quarter-sized = 1.00 inch). Local impacts most likely include dents to vehicle body panels and damage to exposed automotive glass such as sunroofs. Asphalt shingle granules can be knocked loose, accelerating wear on older roofs. Vinyl siding and soft exterior trim may show pitting or nicking. Plants, garden produce, and unprotected outdoor equipment in Whitwell are susceptible to bruising and cosmetic harm.

Structural punctures or catastrophic roof failures are unlikely at this size on intact, well-maintained roofing materials. Buildings with thin, degraded, or previously damaged coverings may show more significant wear. Reported damage in the Whitwell area should be documented with location, time, and clear photographs for insurer and contractor review.

What Contractors Should Know

Safety and access first. Continue monitoring the warning status before conducting hands-on inspections. Prioritize visual surveys from the ground and elevated cameras where safe. Focus initial inspections on vehicle fleets, exposed skylights, gutters, and south- and west-facing elevations that received the brunt of late-afternoon sun. Record roof access points used, take geotagged photos of hail impacts, and note any preexisting conditions observed during the survey.

For repairs, temporary tarping protects interiors while you scope permanent work. Check shingle granule loss patterns to assess remaining service life. Inspect flashings, soffits, vents, and vinyl siding for impact scoring or perforation. Provide itemized estimates that separate hail-related repairs from preexisting damage. Coordinate sequencing with insurers when possible to avoid duplicate work and unnecessary material handling.
