Southern B.C. highways under piles of snow as winter storm hits ahead of Christmas travel weekend

More than a metre of snow has accumulated in some parts of southern B.C., closing major highways and causing chaos on the roadsahead of the Christmas travel weekend.

The CoquihallaHighway, a portion of Highway 5, re-opened Friday evening. Earlier in the day both the northbound and southbound lanes between Hope and Merritt were closed due tospun-out semi trucks and other vehicle incidents.

A travel advisory is still in effect as ofFriday evening between Hope and Merritt because of the limited visibility and extreme snow, with up to 60 centimetres expected by Saturday. Delays are being reported on the roads as crews clear the snow.

Farther south, Highway 3 is closed in both directions at Allison Pass as of Friday evening.

It opened briefly after a nine-hour shutdown beginning Thursday night, but conditions forced the second closure Friday morning which is expected to continueinto the night.

Highway 1 is also closed in both directions, with a travel advisory in effect betweenEagle Pass and Rogers Pass.

The heavy snowfall has heightened avalanche risk across the southern regions. Avalanche control work has closed the roads on several sections of the highways, including parts of Highways 1 and 3.

Heavy snowfall continues

Allison Pass, the highest point of the highway between the cities of Hope and Princeton, hadup to 103 centimetres of snow by Friday afternoon, according to Environment Canada. On sections of the CoquihallaHighway, between Hope and Merritt, between 45 to 86 centimetres of snow hadaccumulated.

The heavy snowfall, caused by a frontal system stalled over the region, beganlate Thursday afternoon and iscausing major traffic disturbances and delays.Thursday night's snowfall was the second most intense 12-hour period of snowfall since the late 1970s, according to the B.C. Ministry of Transportation.

All three major highways linking the Lower Mainland and the B.C. Interior are shut down in some way with the fresh snow created conditions so treacherous thatdrivers have been advised to stay homeif they can.

DriveBC has posted a rareemergency message on its site, saying drivers who takeHighways1, 3, 5 and 5A "do so at risk of becoming stuck or exposed to avalanche hazards."

The heavy snow brought travel on the Coquihalla to a standstill on Thursday night. Drivers sat stranded in their vehicles, watching snow pile up on their hoods and the road ahead, waiting hours for an update.

"It was white-out conditions and heavy, heavy snow," said David McKay, who made the drive from Kelowna to Vancouver Thursday night.

He's been making the drive multiple times a month for a decade and says he's never seen the roads so treacherous before.

Southbound lanes on the mountainous, windingstretch between Hope and Merrittreopened just after midnight PT andnorthbound lanes had reopened around 4 a.m. PT after the lengthy closure.

Weather warnings issued

The storm is expected to move on by Saturday night.

"We're certainly not done with [the snow] yet we're kind of rightin the middle of it. For those who are looking to travel, it certainly may be best to hold off until the system has passed," Ross MacDonald, meteorologist with Environment Canada, said Friday morning.

Wintry weather and sudden snow squalls can make mountain highwaystreacherous, and drivers are reminded to slow down and drive for the conditions.

In Golden, one of the areas where avalanche control work is planned, the power was out for about 1,200 people, according to B.C. Hydro. Images from Friday evening show a snowy Highway 1, which passes through Golden, with the street lights out.

Staff with Yellowhead Road and Bridge, the local contractor responsible for maintenance on the Coquihalla, worked for hours to try to keep the road clear.

"Crews have been out battling that all night long," said general manager Dave Duncan.

Environment Canada recommends that drivers pack an emergency kit in the car with water, food, medications, first-aid kits and a flashlight in case they get stuck on the road. Winter tire regulations are also in effect, with mountain-snowflake tires recommended for rural highways and mountain passes, and mud and snow tires,marked with an M+S symbol, appropriate for most South Coast roads.
