Waubay, SD Hail Storm – June 2025

Waubay, SD saw a concluded severe hail event on June 2, 2025, with verified hail up to 1 inch. The storm moved through during the early afternoon and produced one NWS hail alert for the area.

What Happened

The storm was tracked at 12:36 PM CDT on June 2, 2025, when a severe thunderstorm warning area covered Waubay and nearby locations with a 1-inch hail threat. Dual-polarization radar showed confidence in hail reaching that size.

This was a single-zone storm report. No additional hail alerts were issued for the event after the 12:36 PM CDT alert, and the storm concluded later in the day.

The timing places the hail threat in the first half of the afternoon, when storm structure was strong enough to support large hail production. The radar-derived hail signal was consistent with a localized hail swath rather than a broad, multi-round event.

Damage Assessment

One-inch hail usually marks the point where minor to moderate exterior damage becomes more likely. Metal surfaces can show dents. Roof shingles can lose granules. Soft metals, vent caps, and trim are often the first parts of a property to show impact marks.

Vehicles parked outdoors during the warning area can also show visible hail strikes, especially on horizontal panels. Siding damage is usually less common than roof and vehicle impacts at this size, but exposed surfaces near the storm core can still take hits.

For commercial sites, the most useful checks are often the simplest. Look at rooftop HVAC units, gutters, downspouts, skylight frames, and membrane seams. Window screens, awnings, and condensate lines can also show impact from a brief hail burst even when the broader site does not.

The 1-inch hail threshold does not point to uniform damage across the whole warning area. Impact patterns usually tighten around the storm core and weaken quickly outside it. That leaves some roofs and vehicles with no visible marks while nearby structures show clear strike evidence.

What Contractors Should Know

Start with a perimeter pass. Record roof age, slope, access limits, and visible impact points before anyone climbs. On residential jobs, check the north and west exposures first if they face the incoming storm path. On commercial roofs, inspect soft metals, drains, curbs, and rooftop units before opening up larger sections.

Use a consistent photo set. Capture the property from all sides, then document every dent, bruise, crack, and displaced component with a wide shot and a close shot. For hail claims tied to this event, the most useful field notes are location, time window, material type, and visible size estimates. Keep those notes tied to the 12:36 PM CDT alert window and the confirmed 1-inch hail size.

If the site sits near the center of the warning area, look for clustered impact marks rather than isolated dents. If it sits near the edge, compare the evidence carefully with wind-driven debris and pre-existing wear. The hail pattern for this event was narrow enough that location inside the path matters.
