Grenada, MS Hail Storm – September 2026

Grenada, MS experienced a multi-hour hail event on September 12, 2026, producing a peak reported hail size of 1.34 inches. The storm produced repeated NWS warnings and a radar-detected hail signature during the late-afternoon period.

What Happened

The hail-producing storm moved through the Grenada metro from early afternoon into early evening on September 12. NWS warnings began at 1:28 PM CDT for 0.75-inch hail. Warnings continued through the afternoon with issued times at 2:41 PM, 2:52 PM, 3:40 PM, 4:52 PM, and 5:37 PM CDT, each reporting 1.00-inch or smaller hail under NWS warning only guidance. At 3:31 PM CDT dual-polarization radar detected hail consistent with just over one inch in diameter. The sequence of alerts spans roughly 1:28 PM to 5:37 PM CDT. The event is concluded.

Damage Assessment

Available data show the event produced hail sizes into the inch-plus range across the Grenada warning area. There are no widespread, spotter-verified structural collapse reports in the collected alerts. Localized impacts are most likely to appear on exposed vehicles, vulnerable roofing materials, and uncovered outdoor equipment in the Grenada metro.

Inspect parked cars for paint chips, dents, and cracked glass. Check unprotected rooftop surfaces such as single-ply membranes, older asphalt shingles, and metal flashings for bruising, granule loss, and punctures. Examine skylights, HVAC condenser fins, and exterior siding where physical contact with hail is likely. Prioritize inspections for properties that were within the NWS warning area between early afternoon and early evening on September 12.

What Contractors Should Know

Prioritize assessments in the Grenada metro that align with the NWS warning polygon and the late-afternoon radar signature. Document every visit with date, time, and geotagged photos. Measure hail damage points and include a scale reference in images. For roofs, follow a staged approach: initial visual survey from the ground, followed by drone imagery or a controlled rooftop inspection when safe. Record serial numbers and condition of exposed equipment such as outdoor HVAC units and solar panels.

For temporary protection, apply industry-standard tarping only after a documented inspection and with homeowner consent. Use PPE and fall protection when accessing roofs. Coordinate with insurers and obtain explicit scope-of-work approvals before starting repairs. For claims likely to involve multiple vehicles or structures, provide a prioritized remediation plan that separates emergency tarping from full replacements.
