Santa Ana winds occur in the fall and continue through winter, contributing to some of the region's worst wildfires. The strongest winds arrive Sunday, when gusts of 40 to 50 mph are possible in the Cajon Pass and along the Ventura County coast.
"By the time we get into Sunday morning, 10 a.m., we've got our classic Santa Ana wind here," said NBC4 forecaster David Biggar. "We'll continue to see these winds throughout the entire day for Sunday.
"By 6 p.m., it is still very gust across the Inland Empire. We'll start to see the wind gusts let up just a touch by Monday."
To the north, a large swath of California from the Bay Area to Redding and Fortuna counties is under a more severe red flag warning.
