It will be Friday morning before electric service is restored for all of the Dayton Power & Light customers affected by Wednesday afternoon’s rowdy storms that raked much of southwest Ohio and the Miami Valley.

Those wind-packed storms brought down trees throughout the region, which brought down power lines. Debris was sent flying, especially in the Auglaize County village of Cridersville, where a roof was ripped off a business and a steeple was left bent over. In Sidney, a semitrailer was knocked over by high winds. Corn stalks were laid low in Shelby County. Hara Arena in Trotwood was heavily damaged when poles fell on the building.

At the height of the storms, 48,500 DP&L customers were left without power, said Tom Tatham, director of operations. Extensive damage was done in the northern Miami Valley, in the areas of Coldwater and Fort Recovery, where many poles will have to be replaced, he said.

Significantly high winds wreaked havoc in Montgomery, Greene and Clark counties, he said.

By 5 a.m. Thursday morning, the number of DP&L customers still without power dropped to around 7,800 — approximately 5,800 of that number in Montgomery and Greene.

“We’ll have a full day of work ahead of us,” Tatham said of what the 700 DP&L workers in the field will have to face Thursday. They’ll get help from utility crews from Tennessee and Indiana.

By Friday morning, there should only be individual outages and isolated problems remaining, he said.

Ohio Edison was reporting 40 customers in Clark still without power early Thursday morning, down from a high of 16,000 at the peak of the storms, said Tim Suter, spokesman for the utility.

All of that company’s customers affected by the storm should be back on line between noon and 2 p.m. Thursday, he said.

Following is a timeline of events that occurred as the storms entered the region:

4:30 p.m.: About 12,000 customers are without power in Clark and Madison counties, according to Ohio Edison. The outages are primarily concentrated west of Springfield and include North Hampton and Medway, according to Tim Suter, area manager for Ohio Edison. Suter said the bulk of the outages will be repaired within the next hour or so, but outages affecting smaller numbers of customers might take longer to restore.

4:16 p.m.: DP&L reporting more than 30,000 power outages for the region, and 20,000 of those are in Montgomery County. University of Dayton Magazine tweeted this: “What a storm. Took us by surprise (we do work in a basement) & took down part of @roeschlibrary construction fence.”

He said the exact timing of the storms is still unknown but put the window for possible severe weather between 2 p.m. and 9 p.m. A flash flood watch is in effect for the entire area until midnight. “On top of the threat for flash flooding, we’ll have the chance for some severe weather once again with high winds and hail possible,” Wirdzek said. “The downburst, or straight line wind potential, will increase as the afternoon progresses.” He said storms will likely be more widespread than Tuesday evening.

1 p.m.: A flash flood watch has been extended for all Southwest Ohio and Southeast Indiana counties through midnight.
