Paper says 2 inches along the coast and 2 feet of snow could occur as low as 2,000 feet...
Checked it twice...that is what a meteorologist said according to the report in the Long Beach paper.
Arrives this afternoon....just in time for the Friday afternoon commute...
Who is so diabolical to schedule that arrival time.?
But my trimmed rose bushes are ready...ground has been loosened and fertilizer applied....
But if I see one, I'll report in immediately....lol

I have. Pretty scar and very dramatic. A friend saw one come through the wash by her house. Big wall of water, lots of noise, boulders, etc. Not a cloud in the sky.
Filled the first floor of some homes to the ceiling with mud!
Happened in San Bernandino County in city of Highland...near Redlands.
Viscious winds here in Bakersfield right now. Don’t know the mph, but is is very high.
Not sure where this one happened.
I've been going to the desert for many decades...There are flash flood washes everywhere below high ground...If one is stupid enough to go into a wash before or during heavy rains...??? lol....
Those that know, or have a brain, know it can happen miles away up in the mountains...Water goes down hill...No surprise..
My point is, most flash floods occur where no one is most of the time...Those dumb enough to be in OR live in low ground flash flood areas.....Well...what can ya say? They're going to get wet...
That was Dec 23 of 2010.
Thanks for the report.
I know exactly where it happened Ernest..See the uphill canyon in your pic?
This happened at the bottom or near the low end of a canyon...This never happens on high ground...lol...
People attempting to cross high fast moving water during flash floods or periods of heavy rain, get wet.
Qualcomm Stadium is at the bottom of a canyon....
I talked to my Little(?) sister near Fresno this morning and she said the winds were bad but the heavy rain had bypassed them at that point in tike. She said the snow was down to 5,000’ and the weather channel showed the blinding snow on Donner with all the parked trucks...
Just now getting the leading edge ...street now wet ...between the beach and Los Alamitos Air Station.
I should expect a Freeze....here??
Hey Ernest, I've never actually even seen a flash flood, even when out in the desert camping during *heavy* rains..I visit my brother-in-law in Arizona between Havasu and Kingman. The terrain looks like a moon scape but there are (dry) "washes", some are HUGE that you can tell major amounts of water has flowed through. The funny thing is, I've been there in some heavy rains and there are NO puddles afterward...You can barely tell it even rained. It's hard to believe there can be flash floods in that soil.
You bet....And the reason why few if anyone live around those washes, is they would be long dead...They’re rushing rivers that disappear as fast as they appear.
Yep, you’re about to get hit hard. I used to live in Huntington Beach. (Marina High School grad) Now I live in the high desert of San Bernardino. When we get it, we get it hard. Joe Bastardi promised me a cold, dry winter. Cold I can deal with. Rain I could do without.
No rain here either......yet. The winds have lessened.
Uh Oh... another nonbeliever in Global FReezing!!!!!!!!!!!!!
405 was not so bad right now but our little stretch from la to orange county, 10 miles at most, had two ambulance accidents on it.
We do need more rain so I am ok with it. Want to go home, eat the beef stew in the crackpot, and go to bed early! Rainy days are cool.
Dang this iPad. Crockpot not crackpot!
No, but I was at my son’s practice using my iPad. It always corrects words to what it THINKS I should be typing. It changed my crockpot to crackpot!
The worst was once I was writing a one-word text to my mom and it wrote “testes” instead of what I had wanted to say, but I’d hit send already. Excuse me, but I think Apple should NEVER REPLACE ANY WORD with testes! Just don’t! :)
Well...what can ya say? They’re going to get wet...
