Southern California Edison has shut off power to 4,700 customers in the counties of Los Angeles, San Bernardino, Ventura and Kern as part of ongoing measures to lower wildfire risks in the midst of the Santa Ana winds blowing in Thursday and Friday.

The power provider did not give a break down about how many customers in each county were affected though it maintained that nearly 174,000 remain at risk of the same fate. Many of those affected are in foothills and mountainous areas.

The wind system could bring gusts of 70 mph to areas in Los Angeles County and 60 mph gusts to areas of Orange County and the Inland Empire, the National Weather service has said. Combined with the warmer temperatures and lower humidity is a recipe for wildfires. The low humidity is caused by cold air and a drying-out effect that occurs when the gusts blow across mountain slopes.

Cal State San Bernardino closed its campus Thursday, Oct. 10, because of the anticipated electricity shutdown by Southern California Edison.

MAP: SCE says power outages could come to these areas

According to the SCE website, the company looks at historical data to help predict the likelihood of a wildfire occurring.

“During these events, we may need to proactively shut off power temporarily as a result of elevated weather conditions … that can cause a power line to fall and spark, possibly creating a wildfire.”

An outage will last “as long as the dangerous fire weather conditions exist,” according to SCE.

The utility company cut power to 65 customers in unincorporated Kern County on Wednesday afternoon amid gusty winds though it was restored to all but three of them hours later.

The local outages have arrived as unprecedented outages from PG&E have darkened larges portions of Northern California.
