Update -- 1:45 p.m.
The Trans-Canada Highway will be closed today from 2-6 p.m. for avalanche control in Glacier National Park.
There is no detour available.
Further closures for avalanche control will be required on March 6. The timing and duration of Thursday's avalanche control is dependent on weather conditions.
The snow continues to fall on the mountain passes as a frontal weather system from the Pacific coast moves across the southern interior today.
Snow will be heavy at times, with accumulations of between 10-15 centimetres and up to 25 centimetres for the Kootenay Pass.
Another system will bring another bout of heavy snow to Rogers Pass and Kootenay Pass later tonight and into Thursday.
Motorists are advised to monitor the forecast if they choose to travel on major highways, with DriveBC reporting compact snow and slushy sections along most of the routes.
They also say the Trans-Canada Highway may be closed at some point either Wednesday and Thursday for avalanche control, but the timing and duration of this closure is dependent on weather conditions. Travelers should expect delays of between 2-4 hours when it is underway.
