EF-0 tornado with peak winds around 85 mph began just west of the intersection of P Drive South and 18 1/2 Mile Road. The damage path ended near N Drive South between 20 Mile Road and 21 1/2 Mile Road. Several trees were uprooted along the path, and some unhealthy trunk snaps. There was minor damage to some structures, including a roof off a chicken coop, and an exposed farm outbuilding with some walls collapsed and metal roof material scattered downfield. The end point had an uprooted tree or two, but also numerous trees that had limbs recently torn off presumably not associated with the tornado, as the only torn limbs were those hanging over the road right-of-way.

Written by NWS GRR in the NWS Damage Assessment Toolkit. A survey is revised as better evidence arrives.

39 damage points were recorded along this path by NWS IWX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EFU. The highest wind the damage implies is 160 mph.

• All walls collapsed. Sill plate left in place with straight nails remaining. Sill plate is lacking bolts to concrete (nailed).
• Block home. Cant identify home layou though
• Swab cleaned. Sill plates were screwed into concrete ans ripped out (not broken)
• Large Outbuilding built into hill. Metal anchoring system (like a sill plate) ripped out and uplifted large sections of concrete slab

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

22 minutes of warning. NWS GRR issued a tornado warning for this county at 21:36 UTC, 22 minutes before the tornado touched down, in force until 22:18 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Marginal Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 19:45 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The Grand Rapids radar (KGRR), 99 km away, was scanning. The volume nearest the touchdown began at 21:56 UTC.

15 more have been surveyed in the United States that day, so far.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. A survey can be revised, so the rating, the path and the casualties can all still change.

NWS Damage Assessment Toolkit, the record the survey teams file from the damage, and NOAA Storm Prediction Center storm reports. Neither is the official database for 2026, which SPC publishes in the spring of 2027.
