Weather Advisory Issued For All Areas East Of Los Angeles Starting Tuesday, Peaking Wednesday For Shower and Thunderstorm Activity To Move In


Southern California Weather Force has issued a Weather Advisory for areas east of Los Angeles, Beginning lightly on Tuesday and peaking Wednesday.  Areas within this center San Diego, Imperial, Inland Empire, Las Vegas, High/Low Desert, Wrightwood to Big Bear, Riv/San Diego Mountains so read on for details …

In the article image, you can see the circled area.  This circled area is the area of moisture being monitored from activity over Central Baja, California.  As stated in the previous article (Click here), this would enter the region on Tuesday and last a good 24 hours from then, getting deeper with time.  Tuesday has more of an isolated hit-and-miss look to it.  There isn’t much mid-level instability to get excited about a widespread event, but we could see some showers and isolated thunderstorms in the advisory area on Tuesday.  However, as Tuesday night and Wednesday morning come around, increasing moisture in the mid-levels will make for a widespread shower and thunderstorm event for the advisory area.

An advisory box cannot be made due to the thoughts the entire area will see something … not isolated, more scattered to numerous and it should fill 90% of the advisory shaded zones in the alert system with showers OR thunderstorms.  MId-level instability is more than enough to warrant the risk of thunderstorms developing during that time.  ACtivity will move south to north and should not go west of Los Angeles County.  As stated in that previous article link above, Los Angeles is the border of the dynamic zone.

A weather advisory means that conditions are favorable for showers OR thunderstorms in the advisory zone or that conditions for thunderstorms are borderline and not enough for a full thunderstorm watch on a tougher forecast.

A thunderstorm watch may be issued for Wednesday for parts of the advisory zone if trends continue, the ground zero sections being San Diego north-northeast to the RIV/SD Mountains where the mid-level dryline will exist Wednesday.  If a thunderstorm watch needs to be issued on an upgrade, it will be posted on Tuesday evening across the social media pages below, or the premium email alert system, whichever you are on.

OCEAN:  If you are planning on being out in a small craft, you will encounter the risk of thunderstorms From east of Catalina and San Clemente Island between Orange and San Diego County’s coastal areas mainly Wednesday –
