Major Pacific Storm Ignacio – Category Four System Into Southern California – Sunday night through Tuesday night Forecast – Flood Alerts In Place


Hello again everyone.  I am 90% better and able to get back to work now after I was majorly sick.  Major Pacific Storm Ignacio has been assigned a category four out of six status.  The system will start on Sunday, light, gain strength overnight and into Monday, effecting the metros and high desert areas, but waiting till Tuesday to affect the Imperial to Eastern Riverside Desert areas, exiting our region over the day on Thursday.  This is a prolonged system with the highest rainfall amounts thus far this season in flood prone zones so if you are in my red or magneta warning areas, prepare now …  and therefore I will take it a bit slow on it so read on for details.

I have issued Flood alerts for some areas and that you will see within this article, but I am going to waiting till later Sunday to start issuing snow forecasts simply because this system’s snow levels will be below tropical limits, but above Alaskan storm status, or around 6,000 to 6,500 Feet through most of the lifetime with 5,000 or so for Ventura/Kern Mountains so is prudent that I take this slow and be careful with snow amounts.  I have issued Winter Weather Watches for the mountain areas that will turn to official alerts and snow amounts by Sunday evening.  WIth that being said, these alerts may not be available on Southern California Weather Force‘s main Facebook page and will be on the FB groups so Click here and find yours today

Here are the forecast slides by event that will last your through Tuesday.  Note that the rainfall amounts or flood alert maps are not available for the low desert areas.  This is because we are still far away from issuing official flood alerts and those will go out over the day on Tuesday for Imperial/Blythe/Needles.  You will remain with wind through this event while areas like the IE/OC/LA/SD areas get the rain/flood risks.  Please view them below.  Remember, it goes by zones so you either can find yourself in zone 1,2,3, or 4 and let the freeways be your guides.

Event from Sunday through Tuesday … it does not include Tuesday night through Thursday … which will be available on Tuesday sometime.

April 3, 2020 – National Weather Force​ Networks has noted a light to moderate earthquake in the Anza area. As you know from my March 21st update noting that we are ripe for those, Breathing effects usually come with moderate quakes. I have just gotten over a sickness but I still had everything running. There was a large series of spikes between the 21st and the end of the month.
The Anza Gap sequence fits the breathing effect noted, but the spike on March 25th was the highest in many months, which is a bit concerning at the moment. The sequence could mean something larger in the near term in CA/NV or Northern Baja, Mexico. I returned to work earlier today due to the storm coming into Southern California and Arizona this next week so I’ll leave the monitoring up through the period …
