California is facing a new stretch of hot, dry weather with potentially strong winds that could cause power lines to arc and spark new blazes in parched vegetation that’s ready to burn.
The state's largest utility, Pacific Gas and Electric Company (PG&E) said Saturday a Public Safety Power Shutoff (PSPS) will begin early Sunday morning and impact 89,000 customers overall in portions of 16 counties and a tribe.
Red Flag warnings for extreme fire weather conditions are in effect in northern and central areas of the state at 9 p.m. Saturday and last into Monday, according to the National Weather Service (NWS).
More than 8,000 California wildfires so far this year have scorched 5,600 square miles, destroyed more than 7,000 buildings, and killed 26 people.
Most of the loss has occurred since a massive outbreak of fires was ignited by a large number of dry lightning strikes in mid-August in the northern part of the state.
The renewed concern of weather igniting new blazes came with some 17,000 firefighters still on the lines of 25 major wildfires statewide, according to Cal Fire.
