Forget El Nino, StormFest is about to Hit the West Coast

Things often calm down after January 1 during El Nino years....but not this year...with the U.S. West Coast from central California to Washington State about to be pummeled by a series of storms.   Rain, snow, wind?  Plenty for everyone.

A view of the latest infrared satellite imagery shows an amazing line-up of one storm after another stretching way into the Pacific.  A traffic jam of storms.


Let's examine our stormy future, using a series of sea level pressure forecasts from the UW WRF weather forecast models (solid lines are sea level pressure, shading in lower atmosphere temperature).

At 10 PM today, a  strong low is just off the northern tip of Vancouver Island.


10AM Saturday brings an energetic low center into northern CA.


10 PM Sunday?   Another storm hits central Oregon!  And another system is in the wings.


That storm is right off our coast late Wednesday.

 
El Nino late winters generally have less action---not so this year!   

What about precipitation you ask?   Do you really want to know?  The accumulated total through 4 AM next Thursday is impressive, with 5-10 inches over many mountain areas and even 10-20 inches over parts of northern CA, the Olympics and southern BC.


Snow?   There will be abundant amounts.   For example, here is the accumulated snowfall for the 72 hours ending 4 PM Wednesday.  2-3 feet for the high terrain from the central Sierra Nevada to southern BC.  Our winter ski season is secure.


Wind?  You bet.  Each of these storms will bring strong, damaging winds to a favored area of the coastal zone and mountain peaks.  

There is a silver lining of all this action of course:  it will provide an immense amount of water to fill our reservoirs and enhance our snowpack, a snowpack that is now in pretty decent shape (see latest summary below).  Water resources should be fine next summer.

But all these facts on the ground and favorable forecasts don't stop some of Seattle's wacky local media from talking about drought for our region, with the Seattle Stranger being one of the worst (see below).  Facts should matter---apparently not at the Stranger.

  1. The strange Stranger/Mass beef continues. This particular instance is a story that the stranger linked from the Seattle Times, and the key quote about drought concerns comes from the Washington State Department of ecology drought coordinator Jeff Marti.

  3. Winter rain = Summer fire

    I believe that was last winter, when the Orville dam was failing, with so much precipitation in Northern CA, and the following dry season produced the Camp fire.

    Winter rain = summer fire..

    I don't get this drought thing? Are so many people transplants, that don't realize a wet winter's and dry summers are normal for our region?

    Cliff, maybe do another review on the long term averages for winter wetness and summer dryness.

    Maybe the reality of not too abnormal of a pattern, will sink in with a few more people.

  4. Over the last 30 years precip has increased here. Since the 70's snowpack has increased in the Cascades. Water managers have used increasingly accurate technology to manage the resource - 14/15 is a great example of that.

    And yet every year it is the same. Drought. We heard it this fall (while the Cascades were drenched), just like last fall, and the fall before that etc. etc. Go back to 15/16. Anyone who watched that joke (it's a wet-drought!) unfold knows exactly what Cliff is talking about, and kudos to him for being one of the only sane voices on the subject.

    Seattle water supply is done for this year. It would take unprecedented dryness to change that. If this storm comes to fruition watch for another major managed outflow from our reservoirs.

    Whatever happened to truth... and why isn't that reported (particularly the exceptional job our water managers do) instead of the constant fear-mongering that is so pervasive on this subject? There is a lot of good news here - how about if we hear that for a change?

    1. You got it.The media just loves sensationalism and the left wing publications like to follow their climate change/sky is falling narrative. They need extreme weather events to prove their point and when we get normal weather they still call it a drought! Luckily most people aren't that dumb to believe it. Even in drier than normal winters around here they're still not really a "drought". The last true winter drought was a really long time ago. Way back in 2000-2001. And a wet spring and summer in 2001 quickly solved that problem. Sure we had a drought in 2015 in early summer but if I recall we had normal summer rainfall overall because in late August we had several days of heavy rain.

  5. Lets hope the skiers in my area, including myself, learned a lesson from our two skier triggered avalanches that occurred on Dec 30th. Fierce winds near the Crest at Washington Pass created a lot of wind slab in that area.

    The incidents both occurred in an area locals call "portly basin".

    On Jan 1st, I went back to that same area with the person who triggered the first Avalanche to hear the story,to learn the lesson of this avalanche and of course the ski some fine snow with friends.

    The first avalanche was triggered off of a SSE facing ridge when the skier tested the slope with his weight, stepping off the ridge on to the steep snow slope. The Avalanche ran from the tip of his ski and sympathetically triggered several other slabs off of terrain features on his way down around 800 to 1000 vertical feet. That one could have been fatal if the skier had not tested the slope before committing to the ski descent.

    The second skier triggered Avalanche would be considered a near-miss Avalanche incident because of a skier actually took a ride in that slide and lived to tell the story.

    Apparently that group, one of five groups in the same area that day, was the last group to follow the skin track and took notice of the first Avalanche.

    From what I saw, their skin track veered climbers left off the main skin track and traversed below the steepest part of the ridge nose, which was very noticeably heavily wind loaded even 2 days after the storm.

    The person that triggered that Avalanche reported to nwac that:

    "the first member of our party of 5 triggered a large avalanche on a similar aspect at 6500 ft while traversing with skins on. The avalanche was estimated to be 75 ft wide and ran 400-500 ft vertical and broke near the ridge about 75 ft above him. The slide released on layer of 5-6 mm buried surface hoar at a depth of 2 feet in this wind-loaded location."

    There were 16 people in the same area during a wind loading storm event. Whether you know it or not your decision making is influenced when there's that many people desiring to make multiple ski descents in the same Avalanche terrain. These are called human factor influences. (See skier related heuristic traps)

  6. Part 2

    It's always good to see that no one was hurt and that this near-miss accident was reported to the public so the lessons could be learned and warnings issued.

    One of the reasons why I was a controversial figure at he turns all year forum was for exposing commercial guide related near Miss Avalanche incidents, their reluctance to report those to the public and the reasons why.

    A local guide told once told me to keep quiet about her heli-guide bosses near miss Avy incident where he triggered a Ridge top wind slab avalanche and went for a ride that up wound up burying him with only his hand sticking above the snow. Shetold me it was bad for business to report it to the public. However I believe the public has a right to know the safety records of those they are seeking to employ for guide services.

    This reminds me of my own Avalanche incident concerning a wind slab, which I wrote about on TAY (now deleted along with the rest of my posts by an apparently disgruntled Marcus figure).

    In that incident I popped out of a tree line into a clear-cut logging area right in to funnel shaped gully.

    I thought for a moment that was a beautiful ski line that I stumbled upon and then the habit of my brain kicked in warning me that this was Avalanche terrai. It was on an aspect that we had already determined the 10" of new snow had poor bonding to the old wind polished solar crust. I started to ski off towards the side of the gully.

    As I was doing so, I noticed a crack in the snow propagating around me. I was able to ski off of that wind slab before it broke up completely, undoubtedly saving my life.

    The Avalanche ran about 300 to 400 vertical feet but it exposed many logged stumps and resulted in an 8-foot deep debris pile. This was a terrain trap.

    There's no shame in getting caught in an avalanche. However not reporting one due self-interest gain is questionable Behavior.

    The group that reported their recent avalanche near miss to the public performed a great public service.

    Isn't that standard for accurate reporting our is ethical duty?

    Does self-interest gain outweigh the interest of public safety?

    Not sure where you get your information on snowpack. For the period from 1926 to the present, the only Washington sites showing any April 1 SWE increase (none of which are statistically significant) are those over 4,000 feet in elevation. All the others show decreases, most of which are significant.

  12. Our winter wet-summer dry climate IS typical but may becoming more extreme. The Clearbrook weather station (Station Index 45-1484 at N48'58", W122'20", https://rodericperry.weebly.com/), with precipitation data for 113 years in north- central Whatcom County has a 113 year average annual precipitation of 47 inches with 8.67 inches average between June 1 and September 30 (dry season). Over the last 11 years, the average dry season has been 7.79 inches.

    Yes, facts are important. Unfortunately, your reference all comes from indirect temperature data from satellites, which has only been available since the late 1970's. It is not the MSM that do not accept the UAH satellite temperature anlaysis - it is the Main Stream Scientific Community. In spite of what Senator Ted Cruz says, using satellites to measure surface temperatures is not the best way to do it. These types of measurements have numerous problems. As stated in the National Climate Assessment:

    "For short periods of time, from a few years to a decade or so, the increase in global temperature can be temporarily slowed or even reversed by natural variability (see Box 2.1). Over the past decade, such a slowdown led to numerous assertions that global warming had stopped. No temperature records, however, show that long-term global warming has ceased or even substantially slowed over the past decade.[citations] Instead, global annual average temperatures for the period since 1986 are likely much higher and appear to have risen at a more rapid rate than for any similar climatological (20–30 year) time period in at least the last 1,700 years. [citations] * * * [t}housands of studies conducted by researchers around the world have documented increases in temperature at Earth’s surface, as well as in the atmosphere and oceans."

  14. Mac - I didn't say 1926. I said the 70's, and my source is Cliff Mass:

    March 15, 2018: http://cliffmass.blogspot.com/2018/03/is-western-us-snowpack-declining.html

    "Now a completely independent analysis of long-term snowpack trends over the Northwest U.S. is found in a peer-reviewed paper in the Journal of Climate (A New Look at Snowpack Trends in the Cascade Mountains by Stoelinga et al...found here). They used a statistical approach to secure the snowpack from temperature, precipitation, and streamflow instead of the physical model (VIC) mentioned above. But the same general idea. Their results for 1930 to 2007 are quite similar to those found in the Mote et al (2018) paper, with a 23% decline for the entire period, and increasing snowpack since 1975. I repeat, increasing."

    For 40+ years, Cascade snowpack has been trending higher... and that does not include 2018 which by the end of April was far above average, so tack on another positive data point.

    And... since we're talking about good news, here is more: a post from Cliff from May 25, 2016, talking about how spring melt-out dates are also trending positive (i.e. later) - http://cliffmass.blogspot.com/2016/05/stevens-pass-melt-out.html

    More good news: we have exceptionally talented statewide water managers and - for Seattle - a huge watershed and storage. We can thank our founders for that vision.

    The constant negativity - while the exact opposite is happening - is not healthy. Let's discuss all of these important issues, but let's do it with a positive outlook - especially when the data is pointing in that direction.

    Summers in Whatcom County certainly appear to be drier over the last decade compared to long-term average. It might be a cycle or a long-term trend, but the 113 year record for precipitation in Clearbrook is 8.67 inches June through September. Over the last 12 years the average has been 7.79 inches, or 10% less. The Clearbrook weather site is a great one because it is not located with development or widspread land use change has occurred nearby and it has recorded data for a long time for state weather records. https://rodericperry.weebly.com/

Seems to be consistent over the past few days too, with the snowfall event landing sometime around the 6th, 7th, or 8th. Lets hope we get some snow!

  19. What about temperatures east of the Cascades? Where I live in the Columbia Gorge, a typical winter brings 40 or 50 inches of snow. Last year was only about 25 inches, but the year before was more than 100 inches. This year, we have had plenty of moisture but almost all of it in the form of rain. We've had a total of about 6 inches of snow, with about 3 inches right before Christmas, which was nice.

    I'm not complaining, nor was this unexpected. Other forecasters predicted a warm winter with average precipitation. Cliff, will these storms bring snow to the lower elevations east of the mountains, or will it be rain?

    As for the climate change angle, we can rest assured that no matter what happens, the cult will blame it on global warming -- even if it's a run-of-the-mill season. Ringing false alarms is what they do. But Cliff, how about the weather east of the mountains? Any predictions on what form that moisture will take once it gets over here?

    RE: sunsnow12
    Recently, research has been done and may still be in progress regarding spring snow melt. [CWU geological sciences]
    In some areas on the east Cascade slopes there have been big wild fires. These produce much soot that lands in the trees. It takes up to 3 years for this dark matter to be blown out. Meanwhile, some blows out of the trees and onto the snow. The reduced albedo causes an early melt.
    After the ~3 years the system reverts.
    Trying to incorporate this into a state-wide model will be a Herculean task.

    Meanwhile, official State understanding seems to be region wide less snow and early melt, so less late season run-off.
    Clearly, this requires a "carbon" tax.
