SUMMARY
This is the final post for the 19/20 season. Unfortunate circumstances, but certainly the right calls have been made to close all ski areas. While resorts are closed, there have been mixed messages on uphill travel with some spots still allowing it. The bottom line is that if you get hurt, you're going to tax the hospital system so use common sense! There were some large skier triggered avalanches this last week in Utah (Snowbasin and backcountry near Alta). This Powder Alert is purely broadcasted for both living vicariously through the next big dump or in some areas just getting outside to engage in some safe fun time in the snow. Social Distancing is essential! Please respect your local jurisdicational restrictions and never venture out if you are not felling well. The challenge with COVID is symptoms don't dictate whos a carrier. Lets move on to the forecast and a recap of the 2019-20 season.
Forecast:
I am including many maps of snowfall YTD to see who scored the highest numbers in the West. Next season will likely bring changes how we congregate at ski areas, lifts, etc. My optimism is that you will all be riding powder next year! Will it be deep? Yes! Our forecast usually includes deep snow in the headlines. I provide praise to what seemed like the most difficult choice in history for Vail Resorts (1st to announce closures) quickly followed by Alterra for closing down all ski resorts, even as the deepest storm of the year was hitting the Sierra. While shock rolled through the industry, it was the right decision. That weekend saw over 100 inches of snow for some spots of the Sierra. That decision most likley reduced the spread of CV and will have you coming back for waist deep powder next season.
Vicarious/Quarentine Epic Alert: Significant snowfall is going to be impacting the Pacific Northwest especially late Sunday into Monday. The northern Cascades will reap moderate snow initially that spreads south Sunday night. Heaviest snow Sunday night and Monday will favor the Southern Cascades of Washington and northern areas of Oregon. Moderate snow will continue for the North and Central Cascades of Washington. Expect 14-20 inches for many areas by late Monday with unseasonably cold temperatures. Ironically, this might be one of the colder deeper storms of the season (Quarantine Epic Alert). Live it vicariously and think of the last faceshot you had this season! This storm will be cold, so think back to one of your better days of the season.
That system will bring decent snowfall to central Idaho and eventually the Tetons Monday PM to Tuesday (12 plus). Lighter snow trickles north into Montana, and northern Utah.

Best Chases of the seaon: It’s hard to think back to the single best day. Scoring 12-15 inches at Crystal in January followed by a late night flight back to Salt Lake City. From there it was the deepest day of the year at Snowbird with 28 inches of fresh with Little Cottonwood closing by 10AM (Bonus). Other notable winners were a day storm in Wyoming with 12 inches at Targhee (No crowds), and a sneak up powder day at Jackson. The sneak up storm had 2-3 inches on the snow report with 18 inches by the end of the day. That chase started in Idaho Falls and was purely luck based on webcams and telemetry (The models did not have it). In Colorado we all remember the 3-4 feet that dumped along i-70 closing highways in February. Drove until 3AM on Friday with i-70 closing and reopening. Day 1 of that storm cycle was the let down with wind impacted dense snow (Point it straight) and lots of terrain closures at Vail. Day 2 had the mass exodus from Denver (those insane lift lines) that we fortunately stayed at home. Day 3 was the $$ with addtional snow and new terrain openings at Vail (No lift lines). Was able to catch rope drops for Genghes and Red Square and bolted to Breckenridge for the opening of Whales Tail (One of my favorite lines at Breck). Most of Denver stayed home that day. Biggest Bust of the year: Lake Tahoe chase as resorts closed for the season (The right thing to do) watching 5-7 feet fall in 3 days (Like the carrot hanging on a stick).

Below: Mount Baldy just outisde Los Angeles grabbed a whomping 3 feet in 48 hours. Powderchasers had 1st chair followed by a 2 hour lift line for the 2nd run. No other resort all year had lines like this (Double chair). All of LA was there?
Let me end the season with a look at some data I pulled from the National Resource Conservation Service (NRCS).
This season showed Neutral conditions for most of the west (Neither a strong signal for El Nino or La Nina). We originally felt that all regions of the West had an equal chance of having a decent winter. The season started out very slow for the Pacific Northwest with lots of rain in November and December that suddenly took off as midwinter rolled in. The PNW ended up near to slightly above average especially in the North Cascades. Whistler went from nearly no snow to decent conditions by January. Meanwhile in the Rockies Montana started the season with a bang with snow focussing further south into the Tetons during the midwinter period (JHMR and Targhee had deep snow by early December with much less below 7000 feet). Generally warmer conditions in December created some large variables on snowfall depending on where you chased. Meanwhile, Utah and Colorado stayed near normal throughout the season with generally a good year. There were many opportunities to chase powder especially in the southern regions for November. Arizona who may be the ultimate winner from the maps below, scored cold blower for Thanksgiving where 20-35 inches fell at the Arizona Snowbowl. They already had a decent base before that storm. I blew it and missed this storm! The Sierra, had some decent storms early in the season followed by a complete dry spell mid-season. California plates were evident in the Rockies for many of the holiday periods in January and February. That all changed for the Sierra as March rolled in with some areas reporting over 100 inches at the summits as resorts began closing for COVID. Interior BC scored deep powder early to mid season with many resorts riding full terrain by late December (Warming periods brought increased avalanche danger, especially for New Years).
SNOWPACK- SUMMARY AND AVERAGES THROUGH MARCH 28TH.
Lets look at the the year to date Snow Water Equivelent for many States in the West. This is the amount of water in the current snowpack (Melted water). It is interesting how with a neutral year (Equal chances of average snowfall for the West) most areas ended up near or slightly above normal (The season technically would not have ended so these numbers can change). I believe we initially said everyone has an equal chance of a near normal winter. The Sierra came up short this season with perhaps the desert Southwest being our winners (Utah and Arizona).
Below: The Sierra sits below normal currently. Areas further West or along the Crest are most likely higher than the map depicts.
Below: Arizona scored deep Desert Pow this season. The Snowbowl outside of Flagstaff sits in the San Franciscio Peaks Range where abover average snow fell this seaon. Areas further south saw even higher amounts of moisture. The Verde River Basin south of Flagstaff at 131%!
Below: The Washington Cascades who started out with a bust ended this season with just above normal snowpack slightly favoring the Northern regions. Oregon had less. Both areas will score 12-20 inches next week improving these numbers.
Below: The Western mountains of Wyoming ended the seaon at 108% of normal. Season generally saw multiple events started out warm (Novmeber/December) and trended colder brigning better snow to lower elevations late December or early January. You can see Jackson Snake River Plain near the 108.
Below: Near normal snowfall for most of northern Utah with much higher amounts of water for the southern regions. Slightly below normal for the northern Wasatch (Snowbasin, Powder).
Below: Slightly below average to normal for the Sangre De
