Hydrological Hammer of the Gods

Most likely the only time I will ever report a weather forecast is to bring you this snapshot of Monday’s seven-day Quantitative Precipitation numbers. Note the two biggest digits on the map, centered on California’s Sierra Nevada range: 18 inches and 18.9 inches. That means it’s expected to precipitate 18-plus inches of water around the Sierra crest—accounting for typical 10:1 snow-to-water ratios, that suggests about 15 feet of snow above elevation 8,500 or so. The local weather guru in Mammoth is predicting 12-16 feet on the upper mountain.

The forecast is calling for windy and coldish storming this week totaling out to about 10 inches of precip at high elevations, and then that looming wetter second phase over the weekend with snow levels rising at times to as high as 9,000 feet, or exactly high enough to properly infuriate Tahoe skiers.

The recent temblor activity in the Walker Lane and Sacramento Valley of NorCal has me thinking.... god, she may drop the big one on us!

;)

Batten down boys, Ma Nature has something to say.

I saw that report after I'd checked the NOAA forecast here about half an hour ago. For the first time in my memory, the forecast included a "hydrologic report" in the form of an alert or warning. I checked back a few minutes ago, to see the doppler radar, and noticed that the "hydrologic report" was deleted.

It still predicts a ton of moisture over the Sierra during the next week. Since I have no climbing plans for that time, I'm looking forward to it. I note, however, that the snow level is rather high, at least for the southern Sierra, so I hope it doesn't result in flash floods like 20 years ago. We still don't have our Yosemite Valley campsites back that they closed then, and I'm not sure what Aramark or the current or future NPS would do if given another flood as an excuse to get rid of more of those pesky car campers.

Just remember, those of you who can, that the '97 storm dumped a bunch of fresh wet snow at the passes, on top of a somewhat modest snowpack in the week before New Year, then a HarWhyan Express dumped several inches of warm rain at pass level. The resultant flooding was eye opening.

Is this storm a repeat in the making? We'll find out, in due course of course.

2,000 lbs / 8 lbs/gal = 250 gals

Not nearly enough to do any good, John.

That's dismal, in fact.

Which way do they say the wind is blowing? :0)

The reason Oroville and Folsom are kept low.....

Oroville at 56%
Folsom at 41%
Shasta is quite a bit higher at 73%

They are all about double of what they had stored a year ago at this date..

I'm returning to NV from AK thursday night. Is my place at 5500' and one range east of The Sierra going to be hammered, or is this an over hype like supposed atmospheric rivers of recent years past?
