Remer, MN Hail Storm – July 2025

What Happened

A severe thunderstorm moved through Remer, MN on July 23, 2025, producing verified 1.25-inch hail during the morning hours. The NWS alert area carried radar and spotter confirmation at 7:15 AM CDT.

Field reports showed a broader hail corridor across north-central Minnesota. Spotter-verified reports reached 1.56 inches at Walker 1.0 N at 7:00 AM CDT, 1.47 inches near Boy River at 7:59 AM CDT, and 1.37 inches at Walker MN AWOS at 8:35 AM CDT. Federal Dam reports came in higher, with 2.17 inches at 8:00 AM CDT from a CoCoRaHS station south of Federal Dam and 2.84 inches from the CO-OP observer station 3 WNW of Federal Dam at 8:00 AM CDT.

The same storm produced a damage note at 7:14 AM CDT that described several branches larger than 4 inches broken off. Another report at 7:20 AM CDT noted hail “mostly dime size” and short duration. A separate 7:20 AM CDT report cited sustained tree and structure damage at a city park, and another mentioned damage to a marina. The timing fits a compact morning storm with localized impact points rather than a broad, uniform hail swath.

Damage Assessment

The surface reports show a mix of hail and wind-related impacts along the storm path. In Remer and nearby communities, the field notes point to short-lived but concentrated strikes that broke large branches, affected a city park, and reached marina property. Those observations line up with a storm that produced enough ice to mark roofs, trim, and exposed exterior features, while also leaving scattered structural and tree impacts in open areas.

The most severe ground-truth reports came from farther north and northwest around Federal Dam. Two separate spotter-verified reports there listed 2.17-inch and 2.84-inch hail, both at 8:00 AM CDT. Heavy rain also filled culverts and pushed ditches over their banks at 8:23 AM CDT. That report points to runoff and drainage stress in addition to hail impact.

Walker, Boy River, and Deer River also recorded verified hail sizes from 1.1 to 1.56 inches. The reports cluster along a morning corridor from Deer River south of town through Walker and east of Boy River, then into the Federal Dam area. The distribution shows a line of hail impact points rather than a single isolated strike in Remer.

For contractors, the field picture calls for a roof and exterior review that goes beyond one neighborhood or one roof slope. The strongest reports sit within a short drive of Remer, and the hail sizes increase north and west toward Federal Dam. Crews should expect mixed findings from one property to the next, especially on soft metals, ridge caps, vents, skylights, and painted trim.

What Contractors Should Know

Start with the open exposures. The reports from the park, the marina, and the branch damage show that this storm affected tree cover and outbuildings where wind and hail had room to work. Check fascia, gutters, downspouts, screens, and any metal edges around lakeside or park-adjacent structures. Water intrusion should be verified on structures where hail struck the roof and heavy rain followed soon after.
