...COLD AND STORMY WEATHER PATTERN FOR SOUTHWEST CALIFORNIA...

A DEEP LOW PRESSURE TROUGH PERSISTING OVER THE WEST WILL BRING A
SERIES OF WEATHER SYSTEMS INTO SOUTHERN CALIFORNIA FROM THE NORTH
THIS WEEK. THIS WILL CAUSE COOL WEATHER WITH PERIODS OF RAIN AND
MOUNTAIN SNOW. THERE WILL ALSO BE LOCAL STRONG GUSTY WINDS AT
TIMES...MAINLY IN THE MOUNTAINS AND DESERTS.

THERE WILL BE A FEW LIGHT SHOWERS TODAY. MORE SIGNIFICANT
PRECIPITATION IS EXPECTED TONIGHT AND MONDAY AS A WEATHER
SYSTEM MOVES THROUGH THE MAIN UPPER LOW. ANOTHER WEATHER SYSTEM
COULD BRING MORE PRECIPITATION TUESDAY NIGHT AND WEDNESDAY. THERE
WILL BE PERIODS OF SHOWERS IN BETWEEN THESE DISTURBANCES.

PRELIMINARY RAINFALL ESTIMATES THROUGH THE MIDDLE OF NEXT WEEK RANGE
FROM ABOUT ONE TO TWO INCHES WEST OF THE MOUNTAINS...TWO TO FOUR
INCHES ON THE WEST FACING MOUNTAIN SLOPES AND A HALF INCH TO ONE
INCH IN THE DESERTS. HOWEVER...IN ANY OF THESE AREAS...LOCALLY
HEAVIER RAINFALL COULD OCCUR.

SNOW LEVELS WILL BE AROUND 4000 TO 5000 FEET BY MONDAY AND WILL
CONTINUE THROUGH THURSDAY...THOUGH IT COULD GET LOCALLY
LOWER...ESPECIALLY TUESDAY NIGHT OR WEDNESDAY. THERE COULD BE ONE TO
TWO FEET OF SNOW AT THE HIGHER ELEVATIONS OF THE SAN BERNARDINO AND
RIVERSIDE COUNTY MOUNTAINS WITH UP TO ONE FOOT IN THE HIGHER PARTS
OF THE SAN DIEGO COUNTY MOUNTAINS. SEVERAL INCHES OF SNOW COULD FALL
ON THE PEAKS OF THE SANTA ANA MOUNTAINS. SNOW...BLOWING SNOW AND
DENSE FOG WITH NEAR ZERO VISIBILITIES AT TIMES AND MAKE TRAVEL
HAZARDOUS THROUGH THE MOUNTAINS DURING THIS PERIOD.

PERIODS OF HEAVY RAIN WILL INCREASE THE FLASH FLOOD POTENTIAL.
RESIDENTS LIVING IN AND BELOW RECENTLY BURNED AREAS OR NEAR STEEP
TERRAIN SHOULD BE PREPARED FOR POSSIBLE FLASH FLOODING AND DEBRIS
FLOW. THE SHOWERS WILL ALSO MAKE ROADS SLICK. OTHERWISE...THE
PRECIPITATION WILL BENEFIT IRRIGATION NEEDS. PEOPLE PLANNING OUTDOOR
ACTIVITIES SHOULD MONITOR THE LATEST WEATHER FORECASTS.

STRONG GUSTY WINDS ARE EXPECTED TO INCREASE FROM THE WEST OR
SOUTHWEST LATE TONIGHT AND CONTINUE THROUGH MONDAY. THE STRONGEST
WINDS ARE EXPECTED IN THE MOUNTAINS AND ON THE NORTH AND EAST SLOPES
AS WELL AS IN THE DESERTS. IN THE MOUNTAINS...THE WINDS COULD REACH
25 TO 35 MPH WITH GUSTS TO 65 MPH. IN THE DESERTS...WINDS COULD
REACH 20 TO 35 MPH WITH GUSTS TO 45 MPH AT TIMES.

WINDS THIS STRONG WILL PRESENT A HAZARD TO MOTORISTS...ESPECIALLY
FOR HIGH PROFILE VEHICLES AND IN THOSE AREAS WITH LITTLE OR NO
PRECIPITATION...BLOWING SAND OR DUST COULD REDUCE VISIBILITIES TO
NEAR ZERO AT TIMES.

But the Texas ANG had modern typesetting equipment forty years ago.

LOL... ^THat is a good one!

[BurbankKarl]

Sepulveda Basin closed by LAPD, 12 inches snow in Kern Mountains, mandatory evacuations Yorba Linda, and massive mudslides in the Tea Fire area of Santa Barbara, white out conditions in Cajon Pass

[lainie]

I hadn’t heard about mudslides in Montecito. yikes.

Cajon Pass — KTTV showed 6-8 inches that had fallen on their mobile truck inside two hours’ time

[Two Kids' Dad]

Same thing here in Fountain Valley. Too bad the convertible top has to stay up for the next few days.

And yes, all the best wishes for those in the burn areas.

[ErnBatavia]

[Osage Orange]

Hells bells....you lived in Yucaipa?

I went to school at Crafton Hills College....

Transplanted to OK...in '98

[ErnBatavia]

I remember a customer calling me and asking me where “Yucca-pa” was, as he needed to dispatch a truck to pick up some eggs from “Yucca-pa Egg Ranch”.....it took a sec, but I got his gist.

[Ernest_at_the_Beach]

Big Bear is getting snow I bet!

What is being delivered at your hacienda?

[Ernest_at_the_Beach]

Posting a picture from the area where I was reared...NW Kansas:

**********************************************

Photos of a buried vehicle on October 28, 1997 from a Kansas Blizzard!

Can you see the antenna? - - - - - - - See the antenna now?

Identify correct vehicle! - - - - - - View from opened road.

[ErnBatavia]

Nothing yet in the eastern Coachella Valley, but it looks like it’s gettin’ close!

[BurbankKarl]

someone just hydroplaned off the Vincent Thomas Bridge in San Pedro....

[lainie]

That’ll ruin your day.

The CHP site is really bogged.

Our rain appears to have ended but you guys are going to be dealing with it for a lot longer.

[BurbankKarl]

Socal driver has zero clue how to rock herself out of this situation, and pull into the plowed lane...

[mfccinsd]

We used to have a site that got posted that tracked current rainfall amounts, do you recall what it was? We’ve had heavy, heavy rain for over 90 minutes now in San Diego and we’re all curious how much we’ve gotten. It’s been non-stop...we rarely get rain this heavy for this long in our particular area!

[lainie]

Where were the pics, San Bernardinos?

We got 0.33” out here near Edwards AFB. The radar showed wintry mix/snow near Mohave for quite awhile.

[Ernest_at_the_Beach]

Drawing a blank,...but I found this for the Bay area:

HYDROLOGY-METEOROLOGY DATA REPORT PART 5

and it says.....

THIS PRODUCT CONTAINS PROVISIONAL DATA FROM AUTOMATED GAUGES : THIS DATA HAS NOT BEEN SCREENED OR VERIFIED FOR ACCURACY

******************************

So maybe the San Diego NWS has automated rain gauges?
