Santa Ana Winds to Persist Across Southern California as Midweek Heat Nears Records

Recent rains reduced wildfire risk, shifting concern to crosswinds, falling trees, power interruptions.

Overview

  • The National Weather Service kept wind advisories active for key Los Angeles and Ventura County corridors, including the 5 Freeway and Highway 14, through Wednesday afternoon with 20 to 30 mph winds and gusts up to 45 to 55 mph in spots.
  • Peak gusts remain locally extreme, with a 73 mph reading logged at Sill Hill southwest of Julian on Tuesday as weaker but persistent offshore flow continues.
  • High pressure is driving a pronounced warmup, with many valleys and inland areas forecast in the 70s and 80s Wednesday and much of the L.A. Basin expected to reach the 80s.
  • Forecasters expect the offshore pattern to last through the weekend with winds focused in passes and coastal slopes and a gradual easing late week into early next week.
  • Officials caution drivers, especially high‑profile vehicles, about hazardous crosswinds on routes such as the Grapevine and Cajon Pass and warn of unsecured objects, downed limbs, and isolated power outages.
