Three Brief Tornadoes Identified From Tuesday Morning’s Storms
NWS survey crews said damage patterns confirmed two EF1 twisters, with more checks underway to determine whether a third tornado touched down.
- On Tuesday, August 11, 2026, the National Weather Service confirmed three EF1 tornadoes touched down in Delaware County, Iowa, verifying the twisters through official damage surveys conducted that morning.
- One tornado formed west of Greeley at 7:31 a.m. near Edgewood, while a second EF1 began southeast of Greeley at 7:44 a.m. and a third occurred north of Earlville at 7:45 a.m.
- The second tornado ran 2.63 miles with winds estimated at 110 mph based on "significant damage to two farmsteads"; the third spanned 1.49 miles with a maximum width of around 100 yards.
- Embedded in a larger line of storms, these tornadoes were part of a system the Storm Prediction Center preliminarily determined to be a derecho, producing damaging winds across the region.
- No injuries were reported despite structural damage to farmsteads and trees, as the NWS continues surveying storm patterns to distinguish tornado activity from microburst damage.
