Collins said the storm was an EF4 when it ripped through the Miller Ranch and Amherst areas, the scenes of the worst damage. It had weakened to an EF1 by the time it hit the Kansas State University campus, he said.

Authorities said Thursday that 45 single-family residences were destroyed in the storm, as were two mobile homes and three businesses. An additional 67 residences, three multi-family homes, one mobile home and 10 businesses sustained major damage.

Beyond that, 75 single-family residences, three multi-family structures and 20 businesses took minor damage, and 637 residences, 93 multi-family structures, 20 mobile homes and 10 businesses were affected to a lesser degree.

Those totals do not include Lee School, which also sustained significant damage. Nor do they consider structures at Kansas State University, which reported an estimated $20 million in damage.

About 75 volunteers reported Thursday to assist with cleanup, and more pitched in this morning. City officials, who are coordinating eh volunteer effort, said they expect even more people to show up over the weekend due to decreased work obligations.

Gary Fees, the city clerk who is serving as a public relations liaison during the storm aftermath, asked those dealing in trash removal to sort material into three groups. Those groups were vegetation, large appliances and other trash. He said a determination is yet to be made when a trash pickup will be held.
