More than 300-thousand people in central and southwestern Ohio remain without power this morning as crews work to restore service interrupted by two rounds of weekend thunderstorms. All but a few thousand are American Electric Power customers. The company says they may be in the dark through the end of the week. AEP President Pablo Vegas has pledged crews will work through the weekend to restore service. Ohio is under state and federal emergency declarations. Ohio National Guard members today continue visiting Columbus and Dayton residents to see if they need assistance. The Public Utilities Commission of Ohio will review what lessons can be learned from the weekend power outages after people get their service restored. Chair Todd Snitchler says the commission will examine whether utility companies have been aggressive about keeping trees away from lines and about updating utility poles.
