In anticipation of strong Santa Ana winds expect to sweep through the region Thursday and Friday, Southern California Edison announced it is considering preventive power outages to reduce the risk of wildfires caused by downed power lines.

A team of researchers at UC Irvine says it has developed a machine learning model based on an algorithm that — if given information on climate data, atmospheric conditions and the types of vegetation present — can help determine the final size of a wildfire.

According to the National Weather Service, critical fire weather conditions are expected in Southern California from early Thursday through Friday afternoon, with gusts of 45 to 70 miles per hour.

SCE posted to its website a list of areas in eight Southland counties that might be affected by the “public safety power shutoffs” during the period, including large swaths of La Crescenta, Montrose, La Cañada Flintridge and Altadena. More than 106,000 customers served by the utility in eight counties could experience the shutoffs.
