FULL IMAGE and GPS SUITE RELEASED FOR STORM, INSIDE ARTICLE:  Major Pacific Storm Hunter has officially been upgraded to a Category Five on the Southern California Weather Force scale.  He will hit mainly on Tuesday, starting though west of Los Angeles and Ventura by this afternoon and evening.  The brunt on Tuesday will have damaging winds along a squall-line that will be capable of downing trees and power-lines.  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.

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.”

Master Meteorologist – is a consulting meteorologist for over 50 different 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 20 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. That is fine, the track record of the main office is very high so maintain to follow an event when posted.
