A low pressure system originating from the Pacific will bring a blast of winter weather to southern and central Alberta.
There are winter storm watches in effect for Highway 93 North - Jasper to Saskatchewan River Crossing and Highway 93 South - Lake Louise to Saskatchewan River Crossing.
Elsewhere, special weather statements are in effect from Grande Prairie south to Crowsnest Pass, east to Cypress Hills and as far north as Edmonton.
The snow will begin overnight tonight in western areas and tomorrow afternoon in eastern areas of the province.
By Friday evening some areas may receive up to 10 centimetres of snow. For Banff and Jasper, snowfall amounts may exceed 25 centimetres.
Winds across most of Alberta will gust between 60 km/h and 80 km/h causing blowing snow and reducing visibility.
It remains to be seen how much snow will actually stick to the ground, regardless, driving conditions will be challenging.
