SACRAMENTO, Calif. (AP) -- Pacific Gas & Electric says it's going forward with the second planned power shut-off this week because of growing winds and high fire danger in Northern California.

The utility says blackouts will begin around 2 p.m. Saturday in parts of 38 counties. About 940,000 customers — around 2.5 million people — will be affected.

It's the third preventative shut-off in as many weeks amid concern that gusty winds could knock down power lines and spark fires.

Winds picking up Saturday night could gust to more than 85 mph (137 kph) and make conditions extremely difficult for firefighters trying to tame a huge blaze in wine country.

The power shutoffs will happen in six phases, according to PG&E officials.

The first phase will begin at about 5 p.m. on Saturday, Oct. 26. Customer impacts will include these counties: Amador, Butte, El Dorado, Glenn, Nevada, Placer, Plumas, San Joaquin, Sierra, Siskiyou, Shasta, Tehama and Yuba. The all-clear is expected to be given at 6 a.m., on Monday. Approximately, 205,000 customers will be impacted.

The second phase will occur around 5 p.m. on Saturday, Oct.26, impacting customers in the following counties: Colusa, Marin, Mendocino (south), Napa, Solano, Sonoma and Yolo. The all-clear is expected to be given at 8 a.m., on Monday. Approximately, 256,000 customers will be impacted.

Phase three will begin about 8 p.m. Saturday, Oct. 26, impacting customers in these counties: Alameda, Contra Costa, Monterey, San Benito, San Mateo, Santa Clara, Santa Cruz and Stanislaus. The all-clear is expected to be given at 8 a.m., on Monday. Approximately, 246,000 customers will be impacted.

Phase four will begin about 12 a.m. Sunday, Oct. 27, impacting customers in these counties: Alpine, Calaveras, Mariposa and Tuolumne. The all-clear is expected to be given at 12 a.m., on Monday. Approximately, 86,000 customers will be impacted.

Phase five will begin about 9 p.m. Saturday, Oct. 26, impacting customers in these counties: Humboldt, Mendocino (north) and Trinity. The all-clear is expected to be given at 4 p.m., on Sunday. Approximately, 146,000 customers will be impacted.

The sixth and final phase is scheduled to begin 9 p.m., Sunday, Oct. 27, impacting customers in Kern County. The all-clear is expected to be given at 6 p.m., on Monday. Approximately, 1,000 customers will be impacted.

There is also a wind event expected for the Madera and Fresno area at 10 a.m., on Sunday, but PG&E is unsure when they will shut off power to customers in the area.  They expect to give the all-clear at 10 p.m., on Sunday.

After giving the all-clear, PG&E says it could take up to 48 hours for customers to regain power. They will have to inspect about 31,000 miles before restoring power.

The two previous shutdowns were done amid concern that gusty winds could foul or knock down power lines and spark devastating wildfires.

Weather forecasts are calling for record strong winds to lash much of the region over the weekend, with some gusts hitting 85 mph.

PG&E's warning came as firefighters battled flames in Northern and Southern California.
