The strongest and potentially damaging gusts were expected from Wednesday night through Thanksgiving morning. Gusts to 75 mph (121 kph) were expected near and below Cajon Pass and near the coastal foothills of the Santa Ana Mountains.
“Fire danger will rapidly escalate during the night,” forecasters said.

The Santa Anas brought the prospect of public safety power shutoffs in high-risk areas to prevent wildfires from being sparked if the winds were to damage power equipment or blow debris into power lines.
Southern California Edison said power was cut to more than 8,000 customers in Los Angeles, Riverside and San Bernardino counties as of Wednesday night and shutoffs were possible for more than 170,000 customers in six counties.
San Diego Gas & Electric was considering shutting off electricity to more than 53,000 customers.
Forecasters also warned of a possible overnight hard freeze in the Antelope Valley north of Los Angeles.
