  Burke, Gregory County

  2 injured, $7M damage

  What happened

  A tornado developed and touched down in the heart of town near Washington and 7th streets, causing damage to several trees at the touchdown point. Shortly after, the tornado severely damaged several structures while tracking south, including leveling several buildings at the lumber yard, destroying the civic center, and causing significant damage to the school. The start of the school year was delayed by two weeks due to extent of the damage. Two people were (directly) injured by debris when a garage collapsed on them while moving vehicles to safety. Numerous power transmission poles and lines were removed by the tornado. Around 2 miles south southeast of Burke, the tornado struck a residence causing severe damage to the roof. Shortly thereafter, the tornado lifted before reaching the intersection of 295th Street and 345th Avenue after traveling a bit less than 4 miles. The path width reached a maximum of 75 yards within the city of Burke. Up to 3000 trees were damaged by the tornado in and near Burke. Property damage costs are rough estimates.
