OHIO COUNTY, W.Va. (WTRF) — Power crews have been working around the clock to restore power across the Ohio Valley, but many are still without power.

The Appalachian Power Outage Map shows that approximately 4,200 local customers are still in the dark after high winds knocked trees onto power lines. AEP says this is on 120 separate outages.

The AEP Ohio map shows approximately 2000 residents in Belmont and Jefferson Counties are without power.

The current estimated restoration time for Ohio and Marshall Counties is March 28 at 11 p.m. The restoration for Belmont and Jefferson Counties is unknown at this time.

According to AEP External Affairs Manager, Joelle Moray, more than 1,000 workers are helping restore power, including 600 line workers, 250 tree removal workers and 150 damage assessors.

The greatest damage and the majority of outages are in West Virginia. More than 1,000 storm response workers are helping get trees cleared and power restored.
