| August 2025 | Thunderstorm Wind | Cordova | $1,410,000 | A damaging wind event tracked across Seward County, Nebraska, on the morning of August 9th, 2025, impacting areas from the southwest to the eastern portion of the county. The storm produced a number of strong, measured wind gusts, with the highest recorded being 82 miles per hour from a public weather station 3 miles south-southwest of Seward. Other measured gusts were consistently severe, including 80 miles per hour 2 miles south of Milford, and 76 miles per hour 2 miles southeast of Seward, indicating a widespread high-wind event across the county.||The measured gusts translated into significant damage, with numerous reports estimating winds in the 70 to 80 miles per hour range. Structural damage was reported by an NWS employee 4 miles south-southwest of Garland, where a roof was torn off a shed and large trees were downed. Elsewhere, public reports detailed large trees down on a house and vehicle 3 miles east of Cordova, and a large tree impacting a roof in Seward. These widespread tree and minor structural damage incidents contributed to a final damage cost estimate for public infrastructure of $1,411,213.00. This estimate covers only public assets and infrastructure and does not reflect the total damage sustained by private homes and businesses. |
