Wind speeds are expected to hit between 30 and 45 miles per hour and humidity will drop to the single digits, the NWS reported. Temperatures will reach the high 90s in many areas.

“The big story today is this ridge of high pressure that’s right over us driving these offshore Santa Ana winds,” CBSLA Meteorologist Danielle Gersh said. “Where those Santa Ana winds develop will have very warm temperatures too.”

A heat advisory will be in effect for the San Fernando, Santa Clarita and San Gabriel valleys, the Santa Monica Mountains and several cities in Ventura County from 10 a.m. Tuesday through 8 p.m. Thursday. Temperatures will hit the triple digits.
