Environment Canada has issued a flash freeze warning.
Temperatures are forecast to fall rapidly. Ponding water, slush, and any falling precipitation will freeze as the temperature drops.
Icy and slippery conditions are expected to develop as temperatures rapidly fall below the freezing mark.
Surfaces such as highways, roads, walkways and parking lots will become icy, slippery and hazardous.
Take extra care when walking or driving in affected areas.
Be prepared to adjust your driving with changing road conditions.
It could occur late Thursday afternoon or early this evening.
