For more than two hours Tuesday morning, more than 500 Ames residents in the Top-O-Hollow area were without power.

Customers without electricity after Tuesday morning’s thunderstorm included those living in the Stone Brook subdivision, the North Grand Mall area and along Clark Avenue and Kellogg Avenue south to City Hall, according to the city of Ames.

Donald Kom, director of Ames Electric Services, said there was equipment damage to the Top-O-Hollow substation, including several blown fuses.

“Several weather events this summer have affected our customers, and we always take action immediately to assess the situation,” Kom said in a news release. “We appreciate their patience and understanding as we work as quickly, efficiently and safely as possible to return power.”

Also because of the additional rainfall this morning, water levels of Skunk River and Squaw Creek are continuing to be monitored.

Both are expected to crest at or above Monday’s flood levels Tuesday afternoon or early evening, according to the Ames Water and Pollution Control Department.
