Enhanced Santa Ana Wind Warning Issued For The Prone Zone of November 20th 2023 -

NOTE: Zoom-in Images of the Super High Resolution SCWF Wind Intensity Model for this event will be at this link - https://www.southerncaliforniaweatherforce.com/2023/11/19/enhanced-santa-ana-wind-warning-issued-for-the-prone-zone-of-november-20th-2023/

Southern California Weather Force has issued the Enhanced Santa Ana Wind Warning, which will be stronger than the last warning back on October 27th.

Previous updates used the medium resolution SCWF wind model. This update is using the super high resolution wind model, in-which the zoom in images can be found within this write-up.

A strong ridge to the west will bring cold air into the Great Basin between Nevada and Utah this now. The combination of freezing air in that area and average temperatures here will bring what is called a thermal support pattern. This will bring winds out of the desert and through the mountain passes.

ONTARIO AIRPORT: This will cause delays or even diverts as Level 7 has been detected on the SCWF super high resolution wind model.

CAJON PASS: Level 8 has been detected on the SCWF super high resolution wind model. This means that during the period of this event, especially early Monday, we will have roll-overs of high-profile vehicles, 100% certain we will see that out there below the Cajon Pass in the 210/15/215 triangle zone.

Those of you in the San Diego County Mountains around Campo have a modest level 4, so not too bad, and this will wait till Monday as Sunday you will not have the winds like the rest of the area will have.

I also have included the following images below in zones for who will see what compared to the Raiden Storm Wind Intensity Scale, which does affect some of the desert areas from Kern/Los Angeles, and even out to the Morongo Basin/Coachella Valley and Imperial zones, even areas along the Colorado River Valley through Needles.

Raiden Storm Wind Gust Intensity Scale –

8. Extensive widespread damage.
7. Trees are broken or uprooted, building damage is considerable. – High Profile Vehicle Roll-Over CERTAIN.
6. SOME Trees are broken or uprooted, building damage is possible. – High Profile Vehicle Roll-Over Likely, Do NOT recommend Traveling in this zone. This zone also is the starting zone where trees and powerlines will fall and damage cars and even kill people near or in them!
5. Slight damage occurs to buildings; shingles are blown off of roofs. HIGH WIND WARNING CRITERIA – High Profile Vehicle Roll-Over Possible if weight is not corrected.
4. Twigs and small branches are broken from trees, walking is difficult.
3. Large trees sway, becoming difficult to walk. POWER SHUTDOWN THRESHOLD DURING FIRE WEATHER / WIND ADVISORY CRITERIA

Master General Meteorologist – is a consulting meteorologist for over 50 companies, including energy, agriculture, aviation, marine, leisure, and many more areas. He has certs from Mississippi State for broadcast met and Penn State forecasting certs MET 101, 241, 341 and 361 as a meteorologist, but before then was completely self-taught, barely learning a thing from the schools that he did not already know.

Both short and long-range is very important to know in those jobs so you can bet on accuracy here. He is versed in fields like Western USA, Tornadoes, Floods, Hurricanes, High Winds, Fire Behavior, Snow and Blizzards, Short Range, Long Range, Seasonal, and Life-Threatening decisions with over 25 years' experience, out forecasting all weather services available today with lead-time and precision, which makes him a focus of ridicule and envy.

NOTE: Alerts are posted on here, be it a tornado watch, etc, and these alerts are issued from this office and nowhere else. At times, which is often, you will see an alert forecast posted on here that you do not see elsewhere.
