The city of Westerville felt some of the heat last week as temperatures peaked in the upper 90s and heat indexes topped 100 degrees.

The heat wave didn't cause any serious problems for the city, said Westerville spokeswoman Christa Dickey, but the temperatures did slow some city construction projects.

"(The heat) does slow production down a little and makes it much harder to complete concrete work," city engineer Scott Tourville said. "We did fall a little behind schedule on concrete work because of the heat."

The city's Electric Division did have some power outages to deal with over the weekend as storms rolled through the area, Dickey said.

And the hot temperatures did cause more people to head to the indoor pool at the Westerville Community Center last week, Westerville Parks and Recreation Department director Randy Auler said.

"Our numbers were up. With it being hotter outside, people are obviously wanting to stay a little cooler," he said.

Auler estimated that crowds at the community center pool exceeded 500 during the afternoons last week, which does include groups of day campers who use the pool a few times week.

The heat had the opposite effect at the outdoor Highlands Park Aquatic Center, Auler said.

Daily attendance at the center had averaged around 1,500 people a day, Auler said, but last week, attendance numbers averaged only around 1,100 people a day.

"The numbers were actually down a little at Highlands Aquatic center because it was so hot outside," he said. "I thought we might have a huge turnout at the aquatic center, but it was so hot people didn't really want to be outside."

Forecasters were predicting relief from the heat this week, as a cold front was expected to bring lower humidity and slightly lower temperatures.
