Danvers, IL Hail Storm – September 2026

Danvers, IL, September 15, 2026 — A late-afternoon to early-evening thunderstorm produced hail up to 2.26 inches and generated multiple NWS hail alerts across the Danvers metro area.

What Happened

The storm developed late in the afternoon and tracked through the Danvers metro into the early evening. NWS issued three hail alerts tied to radar-detected hail returns on dual-polarization NEXRAD radar. The alert sequence: 5:42 PM CDT — 1.68-inch hail radar detection; 6:43 PM CDT — 1.00-inch hail radar detection; 8:55 PM CDT — 1.37-inch hail radar detection. The event is concluded.

Radar returns showed concentrated hail cores moving along a confined path through the metro. Alerts were issued at separate times as the storm regenerated and redeveloped cells along its track. Local intensity varied by cell and by time. Observed radar signatures supported a multi-zone aggregate storm report for the Danvers area.

Damage Assessment

Hail sized around 1.0 inch commonly dents vehicle panels, chips paint, and causes minor impact bruising to asphalt shingles. Hail exceeding roughly 1.75 inches increases the risk of shingle fracture, skylight damage, and siding perforations. Given the radar-detected hail spectrum during this event, expect a mix of cosmetic and functional damage where hail fell over populated properties.

Damage is most likely on horizontal and exposed surfaces. Vehicle roofs and hoods, unprotected air-conditioning units, solar arrays, and older asphalt roofs are at higher risk. Broken glass and punctured HVAC fins are plausible where the larger returns overlapped residential parcels. Document all observed impacts with date-stamped photos and location references before any repair work begins.

What Contractors Should Know

Prioritize safety and documentation. Confirm site access and weather stability before mobilizing crews. Photograph roof edges, valleys, ridges, gutters, downspouts, exterior HVAC components, and visible siding at close range and from ground level. Note the time and GPS or address for each photo. Temporary covers or tarps should be installed only when a qualified person confirms structural stability and after utilities are secured.

Scope repairs to match observed impact types and material condition. Expect common repairs: asphalt shingle replacement, dented metal panel repair, siding patching, and minor glazing replacement. For claims work, provide clear line-item estimates with photos tied to locations. Check for secondary damage such as clogged gutters, dented condenser coils, and compromised roof flashings. Coordinate with property owners and insurers before ordering materials or performing permanent roof penetrations.
