PG&E has added three more counties that could be impacted by the possible power shut off Wednesday. Monday the utility added Santa Cruz, Santa Clara, and San Mateo to the list, now making it 22 counties that could be impacted by the power shut off. Butte, Glenn, Tehama, and Shasta are among those counties. PG&E says about 300,000 customers will be affected.

This due to high winds forecast for Wednesday and Thursday along with high fire risk.
