    Temperatures are declining mid-week but are expected to spike by early next week as the Santa Ana winds will return, bringing back warm weather by Saturday. Shanna Mendiola has your First Alert Forecast for Wednesday, Oct. 18, 2017. (Published Wednesday, Oct. 18, 2017)

    Temperatures slowly cool down through Friday with an increase of cloud cover, and humidity as onshore flow increases.

    If you’re headed to the beach, temperatures will still run warm with high surf and rip current risk.

    Moderate Santa Ana winds are projected to return this weekend. Temperatures will heat up once again starting Saturday, air will dry out, and the fire threat will run high once again.

    High temperatures could be breaking records on Monday and Tuesday.
