There is a risk of tornadoes with the system for the Ventura, Los Angeles, and Orange County zones. Heavy mountain snow is also going to hit but the SCWF GPS Model Suite for flood, rain, snow, and wind has been updates so for your area, read on and see the images within, including the brought back snow-level / intensity model at level maps.

TORNADO WATCH: Southern California Weather Force has issued a Tornado Watch effective Tuesday for the Santa Barbara, Ventura, Los Angeles, and Orange County Coast and Basin areas. A powerful storm system will move through the region. Backing southeasterly surface winds along the curvature of the natural Southern California coastline will work with strong low-level forcing. This low-level forcing will bring tops to between 15,000 and 18,000 FT on Tuesday. This, with a powerful 160 mph upper level jet, will make it possible for strong waterspouts to landfall as tornadoes. Given the surface instability and low-level forcing, the best areas will be from Ventura to Orange County with Los Angeles between. Expecting this mainly Tuesday morning ahead and along the main frontal zone, but it could extend a bit into the early afternoon as well. Thunderstorms do not have to accompany tornado dynamics here in Southern California. While they are possible with such lift, they are not needed due to the rest of the dynamics taking hold.

There are 10 counties in the Southern California Weather Force forecast area and the storm is major so I cannot write about each micro-climate sector in this article. I however can show you the images in the SCWF model suite and you will need to know where you are on a map to read them. Everyone should know where they are on a map so this is no excuse.
The maps below are of flood, rain, snow, snow-level, and wind intensity. Each one is clickable. Map 1 is NW SoCal, Map 2 is SW SoCal, Map 3 is SE SoCal, Map 4 is NE SoCal, Map 5 is the Cajon Pass, and Map 6 is the SCV region, which includes Gorman at the top.

Southern California Weather Force is a custom weather alert service that began in September 1999 off and is regarded as the most accurate weather service in the region, offering custom alerts, maps, and models to help save life and property. The work done here is never 100% accurate, but it comes pretty close. Southern California Weather Force runs on zones, so if an event happens in a zone that is 10 miles from the border of your zone, the forecast is still valid to activate your zone’s alert system. A company quote to the public is that of “The Joker” and tells other agencies in weather this all the time… “This world deserves a better class of meteorologist… and I’m gonna give it to them”… out-forecasting even the National Weather Service with lead-time and precision, which makes this service a focus of ridicule and envy in the weather community due to having such accuracy. Alerts issued here are issued custom from this office and this office alone. You may not even hear it elsewhere, but if one is issued near or in your area, listen up because “if you do not wish to die in weather, follow, it’ll save your life one day.”
