Environment and Climate Change Canada has issued ice storm warnings and special weather statements for much of the Southern Interior as a warm front moves through the region.
The Japan Meteorological Agency warned that “freezing rain will develop, especially at high altitudes and highway passes, as warm air aloft moves over existing cold air.”
A warning is in effect for the Coquihalla Highway (Highway 5), Okanagan Connector (Highway 97C), South Thompson, 100 Mile, Nicola, and Similkameen areas north of Kamloops Summit.
A special weather declaration is in effect for other areas of the Southern Interior, including the Boundary Region, Okanagan Valley and Highway 3 between Hope and Princeton.
Environment Canada says freezing rain is expected in these areas, with snow and freezing rain likely further north.
“Freezing rain will either end or turn to rain by Thursday morning as colder air moves in,” the ECCC said. “Surfaces such as highways, roads, sidewalks, and parking lots may become icy, slippery, and dangerous. Severe weather may lead to transportation delays. Power outages to public facilities may occur. .”
Five to 10 centimeters of snow is expected in the northern Okanagan Valley, Shuswap, West Columbia, North Columbia, Kinbasket, North Thompson, Cariboo, Prince George and Chilcotin regions by Thursday, when the storm ends.
The North Okanagan, Shuswap, Chilcotin, Cariboo and North Thompson regions could see a chance of cold rain Thursday morning.
