video showing California getting clobbered my precipitation via two different waves on Thursday, Friday, Saturday, and Sunday this week.
NOAA has been forecasting an Atmospheric River for California this week since last Thursday. Details are becoming clearer at it approaches. Some forecasts are showing as much as 17″ of precipitation for northern California (see forecast map below). Whoa…
NOAA has issued a Special Weather Statement for California calling for a two part storm to drop enormous amounts of precipitation. Snow levels will be around 8,000-9,000′ for the bulk of the storm.
SNOW LEVELS ARE LIKELY TO BE VERY HIGH WITH THIS STORM. SNOW ACCUMULATIONS ARE LIKELY ON THE HIGHEST PEAKS...BUT SHOULD BE VERY LIMITED BELOW 8500 FEET. - NOAA Reno, NV yesterday
NOAA is calling for the Atmospheric River to bring “abundant moisture” including moisture from Typhoon Songda (currently near the Phillipines) to California this week.
“Abundant moisture currently over the western Pacific Ocean (including from Typhoon Songda) will make its way toward the West Coast.
By late this week, locally heavy rain will be possible, particularly along the northern CA coast and across the mountains!” – NOAA Sacramento, CA yesterday
Hurricane force winds accompanied by white-out conditions are forecast in the Cascade Mountains (Mt. Shasta, Mt. Lassen) of California.
Anyone planning to venture onto the Cascade Peaks should very much take this into consideration, as white-out conditions and high winds at or above hurricane force above treeline, will occur, at times. - NOAA Medford, OR yesterday
NOAA has forecast snow levels around 8,000-9,000′ for the bulk of the storm. Mt. Shasta is forecast to see 5-7″ of precipitation which would translate to 5-7 feet of snow up high on Shasta during this storm.
Preliminary expected total precipitation amounts from Thursday morning to sunrise Monday morning are 10 to 15 inches in the Brookings area and the Curry Coastal Mountains, 5-10 inches in other portions of the Coastal Counties, 3 to 5 inches in much of Douglas County and the Cascades and Siskiyous, 5 to 7 inches in the Mount Shasta area, 2 to 3 inches in the usually drier Bear Creek portion of the Rogue Valley and Central and Northern Shasta Valley, and 1 to 3 inches on the East Side. - NOAA Medford, OR todaySnow levels look to be above 8kft for the bulk of this precipitation event, but could dip to between 6kft and 7kft in heavier bursts of precipitation and on the tail end of individual frontal systems. - NOAA Medford, OR today
