Bay St. Louis, MS Hail Storm – August 2025

Bay St. Louis, MS saw a concluded hail storm on 2025-08-24 with a maximum confirmed hail size of 1 inch. The storm moved through the city in the evening and produced a single NWS alert area tied to dual-polarization radar confidence.

What Happened

The storm reached Bay St. Louis at 7:30 PM CDT on August 24, 2025. The National Weather Service alert area called for 1-inch hail, and dual-polarization radar supported that hail detection with confidence.

This was a single-zone event for Bay St. Louis. The alert sequence did not expand into multiple confirmed hail sizes or separate warning areas. The storm is concluded.

The timing places the hail threat in the early evening, when outdoor activity and open vehicles are still common across the city. The confirmed hail size held at 1 inch, which sets the upper end of the observed hail field for this event.

Damage Assessment

One-inch hail can leave visible impact on vehicles, roofing materials, siding, and gutters. Asphalt shingles may show bruising, surface granule loss, or broken tabs. Soft metals can dent. Screens, patio covers, and exterior trim can also show localized impacts.

In single-zone hail events, damage often varies block by block. One roof may show clear strike marks while a nearby property has only minor cosmetic effects. That pattern is common when hail falls in a narrow path tied to a short-lived core or a small swath inside the warning area.

For contractors, 1-inch hail is a useful threshold for targeted roof and exterior inspections. Pay close attention to ridge caps, vents, flashing, window screens, gutters, and south- or west-facing elevations where wind-driven hail can concentrate impacts. Vehicle fleets parked outdoors during the event should also be checked for shallow dents and broken glass.

If you are working claims in Bay St. Louis, keep the inspection focus on the exact storm timing. The hail report came in at 7:30 PM CDT, so roof conditions, parking exposure, and storm duration should be matched to that early evening window. Short hail bursts can leave a narrow field of damage that is easy to miss without a property-by-property review.

What Contractors Should Know

Start with exterior triage in the neighborhoods that sat inside the alert area when the storm moved through at 7:30 PM CDT. Look for fresh impact marks on shingles, granule loss in downspouts, chipped paint on trim, and small dents on soft metal components. Document the storm date, local time, and the confirmed 1-inch peak before inspection notes get split across multiple files.

Keep the scope focused on the hail size that was actually reported. A 1-inch event does not require broad assumptions about severe structural loss, but it does support close roof and collateral checks. On single-zone events, the most efficient fieldwork is usually a straight roof and exterior pass, followed by a vehicle and accessory review where exposure was highest.
