Damaging wind event for Monday night into Tuesday.
Pressure gradient peaks:
LAX-DAG: -8.2
LAX-BLF: -5.5
Upper level support: strong
Cold air advection: strong
Relative Humidity: 20-25%
Expected winds: widespread 30-40 MPH with gusts to 60 MPH.
Santa Ana favored 35-50 MPH with gusts to 75 MPH.
Mountains favored 45-60 MPH with gusts up to 90 MPH, locally 100 MPH.
Only a moderate chance of large fire activity due to the higher humidity and isolated showers/snow in the mountains, but isolated locations out of the moisture shield could see extreme fire behavior on any new starts.
The storm prediction center will be issuing critical delineations despite South Ops not adding high risk days.
On a scale of maximum potential Santa Ana wind events possible for Southern CA I would rate this an 8.5/10.
Confidence on a scale of 1-10: 7
Now from NWS Los Angeles which matches well with my assessment:
