The Allison Pass on Highway 3 was buried by 107 cm (more than 40 inches) of snow in just 24 hours, a record for 24-hour snowfall on that pass.
Environment Canada meteorologist Matt MacDonald says 60 cm (2 ft) of snow fell in a 12-hour period at the Coquihalla Summit from Thursday afternoon, Dec. 19, to Friday.
“That was the second most snowfall in a 10- to 12-hour period dating back to the 1970s. The record heaviest 12-hour snowfall was 65 cm which fell in 2011,” MacDonald says.
Meanwhile, 92 cm (more than 3 ft) of snow fell Thursday through Friday at the summit on the Coquihalla Highway in just 24 hours, forcing closure of both southbound and northbound lanes for hours on Thursday, Friday, and again on Saturday, in one case overnight.
Highways 1 and 3 were also closed numerous times between Thursday and Sunday due to avalanche control, road conditions and collisions.
