Gusty winds and low humidity brought high risk of wildfires to the interior of Northern California on Wednesday and Pacific Gas & Electric proactively cut electricity to approximately 8,400 customers to prevent potential ignitions in the blustery conditions.
Red flag warnings for critical fire danger were to remain in effect until 8 p.m. in much of the Sacramento Valley and adjacent areas to the west, the National Weather Service said.
Pacific Gas & Electric said that shortly before 2 a.m., it began public safety power shutoffs in “targeted high-fire-threat areas” of eight counties. Winds calmed throughout the afternoon, and by 5 p.m. the utility issued a weather “all-clear,” saying it would begin the process of restoring electricity.
Smoke from the wildfires is impacting the Bay Area today, according to Bay Area Air Quality Management District spokesperson Kristina Chu. Chu noted the Fire and Smoke map from AirNow shows that there are more smoke impacts that can be seen around the Bay Area compared to earlier this week.
“The wildfires will continue to emit substantial amount of smoke and is expected to continue impacting the Bay Area for the foreseeable future,” she said in an email to KQED. “We do have a Spare The Air alert in place today and are evaluating conditions for tomorrow/coming week.”
PG&E said that shortly before 2 a.m., it began public safety power shutoffs in small portions of eight counties.
Customers in the “targeted high-fire-threat areas” were notified in advance Tuesday, the utility said in a statement.
The gusty northerly winds were generated in the wake of a trough of low pressure that moved through Northern California on Tuesday, the weather service said.
Public safety power shutoffs are intended to prevent fires from starting when power lines are downed by winds or struck by falling trees or windblown debris. Such fires have caused extensive destruction and deaths in California.
The issue of power shutoffs surfaced in Hawaii after the deadly fire that destroyed the Maui community of Lahaina. Maui County claims Hawaiian Electric Company negligently failed to cut power despite high winds and dry conditions. The utility acknowledges its lines started the fire but faults county firefighters for declaring the blaze contained and leaving the scene.
