Amid the extreme heat, PG&E is warning customers of a Public Safety Power Shutoff (PSPS) that could impact 172,000 customers in 22 California counties. Napa and Sonoma counties could start to lose power at 3 a.m. Tuesday

More than 3,000 PG&E personnel will patrol and inspect some 10,750 miles of transmission and distribution power lines today.

PG&E says the PSPS was necessary because of the significant fire risk posed by the dry, hot weather with very strong winds and dry vegetation. The shutoff impacted approximately 172,000 customers in portions of 22 counties: Alpine, Amador, Butte, Calaveras, El Dorado, Humboldt, Kern, Lake, Lassen, Mariposa, Napa, Nevada, Placer, Plumas, Shasta, Sierra, Siskiyou, Sonoma, Tehama, Trinity, Tuolumne and Yuba.
