Environment Canada is warning Whistlerites to brace for more snowfall this week.
The federal weather agency issued a winter storm warning for the Sea to Sky corridor on Wednesday morning, Jan. 5, that also applies to other areas across southwest B.C., due to the heavy snow and hazardous winter conditions expected to sweep into the region later in the afternoon.
The forecast is calling for 10 to 20 centimetres of snow for Metro Vancouver, and possibly up to 30 cm over Howe Sound and the Fraser Valley overnight and into Thursday. About 15 cm is expected to fall over Whistler until Thursday morning, according to Environment Canada. For Howe Sound, conditions will remain cold enough that snow is likely to continue throughout the day Thursday.
"A low pressure system is forecast to move into southwestern B.C. this evening. Snow at times heavy will begin in the evening and ease to lighter snow by Thursday morning," the warning reads.
"Consider postponing non-essential travel until conditions improve. Rapidly accumulating snow could make travel difficult over some locations. Surfaces such as highways, roads, walkways and parking lots will become icy, slippery and hazardous."
A highway alert was also issued for the Sea to Sky highway ahead of the storm.
