The I-5 Corridor was added to the previously issued Red Flag Warning, and the Fire Weather Watch has been upgraded to a Red Flag Warning with the Eastern Santa Ynez Range added. Areas in the Red Flag Warning will have enhanced offshore winds at times during the period overlapping with the hot and very dry conditions, with humidities falling into the single digits. The hot and unstable conditions will bring very high mixing heights (similar to the Bridge Fire event) which will create favorable conditions for large vertical plume growth with any new fires.
