Aiken, SC Hail Storm – August 2026

A severe hail-bearing storm tracked through Aiken, SC on August 21, 2026, producing 1.85-inch hail and triggering 27 NWS alerts between mid-afternoon and early evening. The event combined multiple NWS warning polygons with radar-detected hail cores and spotter reports concentrated near the city.

What Happened

The storm sequence began with NWS warnings at 2:07 PM EDT (18:07 UTC) and continued through an 8:07 PM EDT (00:07 UTC) bulletin, totaling 27 NWS alerts across the metro Aiken area. Most messages were NWS warning only alerts issued to cover the storm path. Dual-polarization radar detected intensified hail cores in the mid-to-late afternoon. Radar returns at 3:05 PM EDT (19:05 UTC) and 3:46 PM EDT (19:46 UTC) showed near 1.2–1.3-inch hail signatures within those cores.

Two Local Storm Reports from trained observers were submitted from the Aiken area. At 3:56 PM EDT (19:56 UTC) a spotter in the Park Crossing neighborhood reported dime-size hail. At 4:44 PM EDT (20:44 UTC) another observer reported dime-size hail accompanied by heavy rain in a nearby sector of the metro. Those spotter-verified observations align with the broader pattern of warning-area coverage and intermittent radar-detected cores through the afternoon and early evening.

Damage Assessment

Local storm reports recorded primarily small hail and heavy rain. The Park Crossing report noted dime-size stones with no accompanying local storm report of structural or vehicle damage. The later 4:44 PM EDT submission described similar hail sizes with heavy rainfall at the location logged by the observer.

Radar-detected cores near 3:05 PM and 3:46 PM suggest the storm produced pockets of larger hail along a roughly east–west moving path through the metro. Local storm reports do not list rooftop failures, broken windows, or reported vehicle damage within the Aiken municipality in the immediate aftermath. Insurance claims or contractor inspections filed after the event would be required to document any localized cosmetic or functional impacts not captured by initial spotter reports.

What Contractors Should Know

Prioritize inspections in Park Crossing and the neighborhoods along the radar hail cores identified around mid- to late afternoon. Start with a visual, time-stamped photographic survey of vehicle panels, AC condensers, soft roofing details, and exposed metal flashing. The presence of heavy rain concurrent with hail increases the chance that dents or punctures will retain water stains; photograph panels and adjacent components before any cleaning or repairs.

When inspecting roofs, focus on high-exposure planes and end laps where small but repeated hail can abrade shingle granules. Document any missing granules, bruising, or torn underlayment with close-up photos and a fixed reference for scale. For vehicles, use a consistent grid or template to catalog dents and measure diameter and depth when possible.
