Charleston, SC Hail Storm – July 2026

A severe hail storm is tracking through Charleston, SC, on July 10, 2026, producing 0.5-inch stones and spotter-verified hail near the NWS Charleston office. The storm remains active and conditions may still be developing.

What Happened

Dual-polarization radar indicated a concentrated hail core moving across the Charleston metro in the mid-afternoon. The National Weather Service issued an NWS alert area at 3:05 PM EDT for the cell citing the potential for 1-inch hail with spotter-reported confidence. Spotter reports at 3:00 PM EDT documented hail falling at the NWS Charleston location and were relayed to the local storm log.

Radar returns show the strongest reflectivity over the immediate Charleston urban area while the echo maintained organization as it tracked. Field observation and radar data are consistent with a compact hail-producing core passing through downtown and the nearby coastal zones in the late afternoon. Storm structure continues to produce localized core pulses as it progresses across the metro area.

Damage Assessment

Local storm reports indicate surface impacts limited to the NWS Charleston site and immediate surroundings. No widespread structural failures or roof penetrations have been recorded in the current storm log for the metro area. Observers have not filed additional reports of significant vehicle denting or large-area tree limb loss as of this update.

Where impacts are reported, they are consistent with small-diameter stones affecting exposed vehicles and soft vegetation. Public-record observations do not yet show concentrated roof membrane damage or punctures that would require emergency tarping in multiple locations. Field crews arriving in the NWS Charleston vicinity should expect isolated cosmetic damage to siding, window screens, and parked cars rather than widespread structural compromise.

What Contractors Should Know

Inspect vehicles and exposed equipment first in the affected NWS Charleston sector. Small hail commonly produces surface dents and cracked side mirrors. Photograph and document pre-repair conditions with geotagged images. Prioritize HVAC condenser fins and rooftop-mounted equipment that may have thin aluminum or plastic components.

When assessing roofs in the downtown-to-coastal corridor, look for displaced granules, softened asphalt shingle edges, and damage on south- and west-facing slopes where wind-driven precipitation likely concentrated. Focus initial field actions on targeted inspections rather than broad-area shingle replacement estimates. Record exact addresses and time-stamped findings to match spotter reports for claims support.

Ground access may be constrained by standing water on low-lying streets after heavy rainfall that has accompanied the hail core. Use portable walkboards and stable footing practices when conducting gutter and fascia checks. Coordinate with local managers for safe ladder placement near historic structures in central Charleston.
