Storms that tore through southwest Ohio over Labor Day weekend knocked out power to more than 51,000 AES Ohio customers across the region.

Warren County, which includes Mason and Deerfield Township, was among the areas hit. The county showed 227 outage incidents on combined utility maps by Saturday afternoon and dropped to zero by Monday, Sept. 7. Township-level outage counts were not available.

Heavy rain and high winds struck Friday, Sept. 4, toppling trees and downing power lines. By 5:35 p.m. Friday, nearly 35,000 AES Ohio customers had lost power regionwide, WDTN reported. Duke Energy reported 595 outages and First Energy reported 28 at the same time.

Mary Ann Kabel, AES Ohio's director of corporate communications, said Friday that crews were working on downed lines with extra personnel on the street. Crews worked through the night.

A second round of storms moved through Saturday, Sept. 5. By midday, AES Ohio said more than 51,000 customers had been affected in total, with about 10,700 still without power across 634 active outage incidents, according to the Dayton Daily News. Warren County had 227 outage incidents on the combined AES Ohio, Duke Energy, Ohio Edison and City of Hamilton maps at 12:20 p.m. Saturday.

Downed trees caused most of the damage. AES Ohio said in a Facebook post Saturday that high winds sent trees onto power equipment across its service area. Crews had to clear fallen trees and debris before they could safely reach damaged lines.

Warren County's recovery outpaced the rest of the region. By 5 p.m. Saturday, the county was down to a single outage incident. It held at one through Sunday morning.

By 8:30 a.m. Monday, Warren County showed no remaining outages on the combined utility maps. Montgomery County, the hardest-hit area, still had 109 outages at that time, down from 8,118 on Saturday evening.

AES Ohio said in a Facebook post Sunday that restoration would continue into Monday as crews addressed remaining damaged locations. The utility noted that many remaining outages affected just one or two customers but still required full repair work.

Residents who lose power can report outages through AES Ohio's website or by phone. Duke Energy customers can report outages on Duke Energy's website.
