Some more info on that event:
During the later part of January, the lower Mainland and parts of Vancouver Island were hit by the worst blizzard in years, a fierce ice storm and then torrential rains. The “worst time of snow and ice in the lower mainland’s history” began on January 19, a colder day than any on that date in 26 years. Next day, a raging blizzard dropped 2 ft. (60 cm) of snow in Vancouver and up to 4 ft. (1.2 m) in Surrey on its already frozen ground. Drifts 8 ft. (2.4 m) deep were “plentiful.” On January 20, cold temperatures and snowfalls immobilized Vancouver and most of southwestern British Columbia. Vancouver recorded 17.5 in. (44.5 cm) of snow on January 20.

The “most intense (snowfall) in Vancouver’s history” paralyzed all traffic and caused schools, mills, and businesses to close. It caused the “worst traffic tie-up since 1913.” Traffic on the old Granville Street Bridge was interrupted for hours when the swing span froze while open. Following big storms on January 19 and 20, rail service on three railroads running into Vancouver was disrupted over 10 days. Floods and slides claimed the lives of at least 15 people with another three missing. The ice storm of 1935, described as the “worst storm of the century,” was far worse than previous “silver thaws” in 1912, 1917, and 1933.

According to records kept by F.B. Dill, a member of the University of British Columbia Buildings and Grounds, between January 11-18, 22 in. (55 cm) of snow fell. A snowfall of 5 in. (12.5 cm) on January 11, was the beginning of nine days of unusual cold snowy weather. On the morning of January 17, North Hatzic and Mission-Matsqui at the bridge over the Fraser River recorded temperatures of -5F (-20.6C) and –7F (-21.7C), respectively. On January 19, temperatures were recorded below 0F (-18C) in the New Westminster residential districts and in the city 3F (-16.1C). At 7:30 a.m. January 19, the temperature dropped to 2F (-16.7C). By the early morning of January 20, 18.5 in. (46.3 cm) of snow had fallen in 24 hours, breaking all records and bringing the measured total of snow since January 11 to over 40 in. (100 cm).

The cold weather was general throughout the province with temperatures in the Okanagan plunging well below 0F (-17.8C). The next day it reported the coldest weather in 26 years with a temperature of 4.3F (-15.4C) in Vancouver. According to E.B. Shearman, local Dominion meteorologist, the greatest accumulation of snow for a short period in 38 years, closed all streets to traffic. In the country, some snow piles became solid ice.

Later on January 21, the heavy rain in Vancouver turned once more into sleet. In the Fraser Valley, “silver thaw” froze onto powerlines to a thickness of 10-in. (25 cm). By the afternoon, the crashing lines had isolated Chilliwack, already covered by 29 in. (72.5 cm) of snow. Both the CNR and CPR were unable to move and would not for nine days. No trains arrived at New Westminster since January 20.

Dec 2022 would be the new Dec 1996. Well a mini-Dec 1996 at least.
It's called clown range for a reason.

Anyone drive Highway 1 through Coquitlam/Burnaby lately?

Reminds me of driving the Coq or Interior highways during winter.

and in all of this mess with the AR's incoming, the Similkameens looks to mostly escape with plenty more snow on the way over the next 5-7 days :clap: :clap:
Looking forward to our first 3 day stretch of sun and 20c++ 8-)
