SCWF Flood Watch Issued For Southern California -
Southern California Weather Force has issued a Flood Watch effective Wednesday to Friday of this week for the following zones;
Zones Affected: Imperial, San Diego, Orange, Riverside, San Bernardino, Los Angeles, Ventura, Santa Barbara, and San Luis Obispo County ... Kern County Mountains ... Baja, Mexico ...
Discussion: As stated in previous updates, the 'Raiden Storm Pattern' was announced. A Raiden Storm Pattern means the pattern had confidence to call the event and named after the discoverer like a comet.
With any case, confidence was high then and it is even higher now. Heavy rain from the Tropical System known as Mario will be in the area Wednesday to Friday. This isn't a normal 'monsoon' burst for the mountain and desert areas only ... but it will be an upper dynamic pushed north 1000 miles from the system that will arrive. This, with the upper divergence (lift) from the low pressure center offshore California will work in unison to bring rainfall to all the sectors equally, from coast, valley, mountain, and deserts ... including the offshore island regions.
Interests on Saturday as I have seen in here should be fine as you are between systems ... outdoor plans look fine ... this window is Wednesday, peaking Thursday, and spilling into Friday.
Our ZoneWatch app is going to be updating on this pattern, so if you have not tried the trial out, or even have it as a tool, it's highly recommended as I am a major part in the updates from it, direct to you.
