I think they should take out a few more flood control dams so that the rivers can run their natural course. It’s the environmental correct thing to do.

I wonder if the Central Valley will, at long last, get some rainwater. Not that it matters in wintertime.

I just hope I won't need chains back and forth to Vegas during X-mas.

All this water is too much at once. Can you imagine all the mud and slides this will create?

It was a moderate rain that greeted me when I headed for the Freeway a bit before 11AM. I found light traffic on the 101, moving at 50 - 60mph, versus the normal 70-75mph... not so bad really.

In the mountains of Malibu there were fewer rock slides than I expected, but things will change for the worse later today and tonight, as the heavier rain arrives.

Here's a snapshot of rain headed toward Malibu at 12:30PM - not what I'd call heavy just yet... just a few red-spots, and they move through very quickly, as this whole front is very fast-moving.

I’m confused...is this caused by global warming, or if there was a drought would that be caused by global warming?

"...pretty much continuous here since Friday..."

Same for most of So-Cal... but, we escaped the harder rain that went to mid and northern CA - thankfully.

BUT, here's a look at what is likely coming... (Unisis forecast) - the four panels (all in GMT - 'Universal, or 'Zulu' time) relate to 4PM PST today (upper left) - 4AM PST Tuesday morning (upper right) - 4PM Tuesday afternoon PST (lower left) - and Wednesday morning 4AM PST. The panels cover the entire US, and show lots of snow for parts of the Northeast (different time zones, of course.)

Raining like the dickens in Long Beach right now.
Forecast is for continual rain, heavy at times, through Wednesday night. Unbelievable.

Why do I think all these “weather warnings” for California are nothing more than a setup for declaring an “emergency” and justifying a request for zillions of dollars from Washington DC?

Statement as of 1:08 PM PST on December 20, 2010

The National Weather Service in Oxnard has issued an

* Urban and Small Stream Flood Advisory for...
southern and central Los Angeles County in southwest
California... this includes the cities of... Tujunga...
Sunland... Sierra Madre... Lake View Terrace... La Crescenta... La
Canada/Flintridge... Monterey Park... downtown Los Angeles... Long
Beach... Diamond Bar... Acton...

* until 400 PM PST

* at 100 PM PST... rain gauges and Doppler radar indicated an area of
moderate to locally heavy rainfall over much of Los Angeles
County. Rainfall rates around one quarter of an inch per hour are
expected to continue into at least through the afternoon... with up
to around one half of an inch per hour likely in the mountains
and foothills... especially in the San Gabriel range. This area
covers recent burn areas... including the station burn area.

Minor mud and debris flows are possible with such
rainfall intensities... especially in and around the recent burn
areas. Ponding of low lying roadways should be expected.

Lancy, you can go to the source of that HERE.

Once the page is loaded, look on the left under Forecasts and click on NAM/Wrf Model. When the four panel picture pops up - click on it to see it enlarged.

I use that site to see what is coming across the Pacific - as the news media never shows it. On their main page when it first comes up (link at the top) - click on the words, Enh IR Satellite Image - a picture of the USA is shown (weather overlay) - then at the top middle you'll see REGION - click on GOES-W to see the Pacific Ocean, Hawaii, etc. Then click on Loop12 - to see the last 12 hours. Watching that will give you a very good idea of 'what's coming!!'
