The Pacific Gas & Electric Co. began shutting off electricity Monday in three of 11 counties threatened by high fire danger — the first of the deliberate outages were made in the Sacramento Valley but could grow across Northern California amid forecasts of “unseasonably hot” temperatures, high winds and dry conditions.

Pacific Gas and Electric Co. announced that 13 counties, including Butte and Colusa, will likely experience public safety power shutoffs.
