5 Freeway corridor near Santa Clarita, Western Santa Monica Mountains Recreational area, Santa Susana Mountains, Southern Ventura County Mountains and Western San Gabriel Mountains/Highway 14 Corridor are the focus of a wind advisory issued at 12:55 p.m. on Tuesday by the National Weather Service. The advisory is in effect until Wednesday Jan. 14, at 2 p.m.

Overview

  • The National Weather Service expanded and extended wind advisories in typical corridors, including the I‑5/Highway 14 areas, with northeast winds of 20 to 30 mph and gusts up to 45 mph, isolated 55 mph.
  • Forecasters say the strongest winds are increasingly confined to passes and coastal slopes, with windy spots seeing 35 to 50 mph gusts and broader areas experiencing lighter breezes.
  • Temperatures are set to peak on Wednesday, with much of the Los Angeles Basin forecast to reach the 80s and widespread 70s to 80s persisting through the weekend.
  • Hazards include unsecured objects being blown around, downed tree limbs and sporadic power outages, plus hazardous crosswinds for high‑profile vehicles on mountain and freeway corridors.
  • Recent storms have lowered immediate wildfire risk by keeping fuels moist, though saturated soils raise the chance of tree and utility pole failures during gusts, as localized peaks near 72–73 mph were observed at Sill Hill in San Diego County.
