October 2019 was exceptionally cold in the Northern Rockies of both US and Canada. There were several small storms in northern regions and particularly in Colorado. The first half of November was bone dry in the western US with no area receiving more than 3 inches snow and most getting zero. Threfore most October snow melted out and is not included in the table of snow totals below. During the third week of November a moderate 1-2 foot storm came mostly through the Southwest while a few inches fell in some northern regions. During Thanksgiving week a strong storm dumped 2-4 feet in California and 4-6 feet in Utah. During the first week of December California got another 3-4 feet and much of western Canada 2 feet with other regions averaging no more than a foot. There was scattered snow over most of the West during the second week of December with the most falling (2-3 feet) in Utah and Colorado. The Pacific Northwest and western Canada were the focus of storms during the third week of December, but the Northwest and much of the US northern Rockies were still seriously deficient in snow for the holidays. California and Utah's Cottonwood Canyons had the most snow at Christmas. The Southwest and some of western Canada had strong storms over the holidays while other regions had lesser amounts.
In early January the storm track shifted north, dumping in the Northwest, Northern Rockies and western Canada. This pattern continued for the entire month, dumping heavily over the northern regions and as far south as Oregon and Utah. During the first week of February a dense atmospheric river tracked from Washington to northern Utah and Colorado. These states were overall favored throughout February, with other ski regions slighly below average except for California, which had its driest February on record. Nearly all western regions got 1-2 feet of snow during the first half of March. A major storm hit the Sierra during the mid-March COVID-19 closing weekend. Late March snowfall was 4 feet in Utah and about half as much in other western regions.
As of the evening of March 15, the vast majority of US ski areas closed due the COVID-19 epidemic. Several did not announce until after the close of that ski day. A few areas remained open into the next week but only a handful were open the weekend of March 21-22. The final areas to close were Lookout Pass in Idaho/Montana and Powder King in far northern B.C on March 25.
With the COVID-10 closings, online snow totals are only being published now by a small fraction of the ski areas that did so before. In some cases perhaps that data is still being gathered but not published in order to discourage visitation. But there will undoubtedly be cases where this season's data will be incomplete. In general I resist the use of SNOTEL water content to estimate snowfall. But for areas marked with an * the snowfall between March 15 and 31 is based upon SNOTELs located in or very close to the ski area in question. I normally write a Season Progress Report around the second weekend in April, but March 31 will be the last for 2020 due to the sketchy online data. I still hope to get official data from most resorts in May and produce the Season Analysis and Summary by mid-June as usual.
California: Mt. Rose opened its beginner lift weekends
starting Oct. 25 and Mammoth opened Nov. 9. The first natural
Sierra snow Nov. 20 was only 2-6 inches but 2-3 feet fell over
Thanksgiving with another 2-3 feet later that weekend.
3-4 feet during the first week of December brought Mammoth to full
operation with the most open terrain in North
America, while low elevations at Tahoe saw rain. After about 2 feet
in mid-December, most terrain at Tahoe was open for Christmas
with base depths of 4-6 feet. Late November snowfall was 3-4 feet
in Southern California (soon degraded by rain) and 6 feet in
Arizona, in full operation by early December. The post-Christmas storm
dumped up to 3 feet in Southern California and Arizona
but mostly missed the Sierra. Light rain degraded surfaces below 8,000
feet at New Year's but a few inches of snow fell later north
of Tahoe. A few modest January storms totalled 3+ feet at some Tahoe
areas but only 10 inches at Mammoth. The first half of February
was dry with upslope winds degrading exposed surfaces. No one in the
Sierra got more than 4 inches new snow during the record dry
month. March began with about a foot of new snow. The mid-March storm
ranged from 4 feet at Mammoth to 8 feet NW of Tahoe. Late
March snowfall was about 2 feet. The last areas open were Dodge Ridge
March 17-19 and China Peak and Mt. Baldy March 19-20.

Pacific Northwest: In October Hood Meadows had 31 inches snow and Mt. Bachelor had 13 inches but the base
melted out by mid-November. Late November snow averaged 2 feet in Oregon declining to less than a foot farther north.
This was the driest November on record at Whistler and in Seattle. Despite 2 feet in the first half of December and 3
feet before Christmas, this region was still far behind schedule, with Whistler having record low ~30% open terrain over
the holidays. Mt. Baker opened Dec. 14 and Stevens Pass Dec. 21. More Northwest terrain opened during the second half
of December, but the holidays were low tide with base depths averaging 3 feet. In early January it snowed 5-6 feet at
Whistler and in Washington and 3-4 feet in Oregon. After avalanche control Whistler reached full operation January 16.
It snowed another 4-5 feet over the entire region in mid-January. Late January snowfall ranged from 3 feet in Oregon to
5 feet from Stevens north to Whistler. Surfaces were difficult with rain to 5,000+ feet at the end of January, but it
dumped 5 feet in Washington in the first half of February and about half as much in the rest of the region. During the
second half of February it snowed 4 feet in Washington and about half as much elsewhere. Early March snowfall was
two feet with temperatures below average. Second half of March snowfall was 2-3 feet with unseasonably cold temperatures.

Canadian Rockies and Interior B.C.: October snowfall was
widespread in this region but November snowfall was significant
only well north of the US border. Lake Louise opened a week early on
November 1, and had the most terrain open in North America
in November. Most areas have received 2-3 feet in the first half of
December and 3 feet the week before Christmas. Overall base depths were
4-5 feet and most terrain was open for the holidays. Silver
Star and Sun Peaks reached 90+% open by Christmas. The Okanagan areas
got 2+ feet of snow during the holiday week with lesser
amounts farther south and east. The early January Northwest storms
dumped 3-4 feet at many of these areas. Mid-January snowfall
ranged from a foot at the Banff areas to 4 feet at Fernie and
Whitewater. 1-2 feet fell in late January and 2-3 feet in the first
half of February. Most areas got about 2 feet of snow during the
second half of February with lower amounts near the US border.
Early March snowfall has been 2-3 feet with cold temperatures.
Hydrology sites in western Canada are in general not that close
to any ski areas and the data is less user friendly than US SNOTELs.
From OpenSnow forecasts, snowfall during the second half of
March was around 2 feet. Only Revelstoke has updated snowfall online.
Last day for Red Mt., Panorama and Big White was March 16.
Last day for Apex, Marmot, Lake Louise, Sunshine and Castle Mt. was

U. S. Northern Rockies: Grand Targhee had 40 inches October
snowfall but postponed opening to November 29 due to the dry month.
Late November snow was about 2 feet in Wyoming and Sun Valley but less
than a foot elsewhere. First half of December snow was 3 feet
in the Tetons and 2 feet farther north. About a foot fell during each
of the last two weeks of December. Holiday base depths were 4 feet
in the Tetons but only 3 feet farther north. The early January
Northwest storms were 5 feet in the Tetons and 3 feet farther north.
Mid-January snowfall averaged 2-3 feet. Late January snowfall was 3
feet in the Tetons and 2 feet farther north. The early February
storm dumped 4-6 feet at Brundage, Bridger and in the Tetons, with no
more than half as much elsewhere. Latter half of February snowfall
ranged from 2+ feet in the Tetons to less than a foot in Idaho with
Montana in between. Early March snowfall was 2 feet in the Tetons
and near the Canadian border and one foot elsewhere. Big Sky was 90+%
open from late January to March 15. Late March snowfall was 1-2
feet. This was the region where ski areas stayed open the longest.
Last days: March 17 for Bogus Basin and Tamarack, March 20 for
Montana Snowbowl, March 22 for Discovery and March 24 for 49 Degrees
North.

Utah: The October cold reached as far south as Utah, setting
records near the end of the month. The Snowbird SNOTEL's 40 inches of
October snowfall shrunk to a 9 inch base before a few inches fell
during the third week of November. The Thanksgiving week storm dumped
4-6 feet,
bringing early season base depths to 3-5 feet. More terrain opened in
early December once snow was stabilized plus up to a foot of new snow.
3 feet of snow the second week of December opened most terrain in the
Cottonwoods on a 5-6 foot base. About two feet fell during the second
half of December in the Wasatch but nearly twice as much in the south
at Brian Head. Early January storms totalled 3-4 feet in the
Cottonwoods and 2 feet elsewhere. Mid-January storms totalled 5 feet
in the Cottonwoods and 3-4 feet elsewhere. Late January storms averaged
3 feet in the Cottonwoods and half as much elsewhere. 4 feet from the
early February storm closed Little Cottonwood for 2.5 days, while other
areas got half as much snow. Second half of February storms were 2+
feet in the Cottonwoods and half as much elsewhere. First half of March
snowfall was 2 feet in southern Uath, 1.5 feet in the Cottonwoods and
less than a foot elsewhere. 4 feet of snow fell during the second half
of March.

Northern and Central Colorado: Early openings on snowmaking
were A-Basin Oct. 11, Keystone Oct. 12 and Loveland
Oct. 25. Most of the 3+ feet of October snow was lost during the dry
first half of November so open terrain from Thanksgiving
into early December was well below average on base depths averaging a
bit under 2 feet after average snowfall during the second half of
November and less than a foot during early December. Three feet of
snow fell Dec. 12-14. Only a foot fell during the second half
of December but 3 foot base depths and open terrain were average over
the holidays. Early January storms were about 3 feet at
Steamboat and averaged half as much elsewhere. Mid-January snowfall
was 1-2 feet and late January snowfall 2+ feet. The rare
atmospheric river dumped 4-5 feet of dense snow in early February.
Second half of February snowfall was 2-4 feet and early March
one foot. A-Basin was 90+% open since mid-January. Second half of
March snowfall was close to 2 feet.

Southern and Western Colorado: The Rocky Mountain Biological
Lab at Gothic (between Crested Butte and Aspen)
had 20 inches October snowfall but lost its base during the dry first
half of November. Wolf Creek had 22 inches October snowfall
and Monarch 38 inches, so both opened by Nov. 1. The Southwest was the
region most favored during the third week of November plus
about 3 feet of snow during the ensuing two weeks. A mid-December
storm averaged 2 feet at most areas but 4 feet at Monarch.
Base depths were 3-4 feet at most areas and 5 feet at Wolf Creek and
Monarch after up to one foot of snow the week before Christmas.
The Southwest storm after Christmas dumped 4 feet at Wolf Creek and
about 2 feet at other southern areas. In early January it
only snowed a few inches in the Southwest but about a foot farther
north. Mid-January snowfall was 3 feet at Wolf Creek and 1-2
feet elsewhere. Part of Crested Butte's North face opened January 15
and Taos' Kachina Peak lift opened January 18. Late January
snowfall averaged 1 foot and first half of February 2 feet. Second half
of February snowfall was two feet from Aspen to Monarch but
only a foot in the Southwest. Early March snowfall was 1-2 feet and
later Match snowfall was 2 feet. Ski Apache was the last
Southwest area to be open to March 22.

Northeast: The first openings were Killington Nov. 3, Mt.
St. Sauveur Nov. 8 and Sunday River Nov. 9. Early November weather
was favorably cold but there was mixed precipitation late in the month.
Terrain expanded some in early December with 1.5 feet of new
snow. Rain on Dec. 14 depressed trail counts. There was some recovery
before Christmas, but a tough holiday week with some freezing rain.
Conditions in early January improved with 1-2 feet of new snow, but it
rained the second weekend. Conditions improved with up to 2+ feet
of snow over MLK weekend and another foot later in the month. The
first half of February was excellent with cold weather and 3 feet of
snow in northern areas. Northern areas got another 3 feet during the
second half of February but totals were less than half as much farther
south with some rain as well. Early March had considerable
melt/freezing with trail counts declining during the second week.
Percents open:
Hunter, Okemo, Sunday River, Sugarloaf, Tremblant closed March 14 and
St. Anne March 15. Smuggler's Notch's last day was March 17
