Power shutoffs could affect over 300,000 Southern California Edison customers amid increased fire danger

Tens of thousands of Southern California Edison customers could see their service temporarily shut off as part of a "public safety power shutoff" aimed at reducing the risk of fire amid windy and arid conditions, the utility said.

According to Edison's website, 308,046 customers were under consideration for shutoffs as of Wednesday afternoon.

Los Angeles and Ventura counties could see the most outages, with over 66,000 and over 94,000 customers affected, respectively.

The shutoffs are planned as the region expects to see a high potential for fire danger, with powerful Santa Ana winds and hot, dry conditions.

Cal State San Bernardino has announced that its campus will be closed Thursday in light of the high winds, fire danger and possible power outage.

Campus officials will decide Thursday whether to remain closed Friday, when similar conditions are expected. The latest campus alerts can be found here.

In San Bernardino County, over 63,000 customers could be left in the dark. The San Bernardino County Fire Department moved resources and personnel into position across the region, with several strike teams ready to respond should a fire break out.

Residents across the region were gearing up for those potential power outages. Thomas Scott prepared his Rialto home for the worst by clearing his roof of pine needles to decrease the chances of wind-blown embers setting it on fire. He also has an evacuation plan.

SoCal is expected to see a return of strong Santa Ana winds which, combined with low humidity, can lead to a quick spread of brush fires.

"We're looking at a recipe for an explosive fire. Should we get a fire that starts with wind on it to carry it from those ground fuels... into those now heavier fuels that are now dry and ready to burn," said the department's Eric Sherwin.

"Turning off our customers' power is not something we take lightly, but PSPS events are one of the ways we can better ensure the safety of the public, our customers, and our employees," Edison said in a statement.
