Another round of snow starting this evening and a bitterly cold day for the south coast is forecast for Monday.

Snowfall of between 10 to 15 centimetres is expected tonight for parts of the Lower Mainland, Fraser Valley and the Coquihalla to the Okanagan, according to Environment Canada.

The culprit is a low pressure system settling in Washington State as of tonight.

鈥淭he associated front will brush through the very southern part of British Columbia giving another round of snow starting late this evening,鈥� according to the weather warning Dec. 19.

Snow will taper off late Tuesday morning on Vancouver Island and Tuesday afternoon on the mainland.

鈥淏e prepared for unusually cold temperatures and strong winds,鈥� along with snowy conditions.

If the snow wasn鈥檛 enough, strong outflow winds and wind chill values are coming along for the ride with the threat of bitterly cold temperatures minus 20 to minus 25, and strong winds, through the Fraser Valley between Monday and Thursday.

The arctic front has ushered in a cold airmass for much of the south coast.

鈥淪trong outflow winds are bringing temperatures 5 to 10 degrees below seasonal normals.

鈥淲ind chill values will approach near minus 20 over the majority of the Fraser Valley except near minus 25 over Fraser Valley east including Hope.

As always the recommendation is to adjust driving with changing road conditions.

鈥淪urfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow.鈥�

Snowfall of similar severity is forecast for Coquihalla Highway - Hope to Merritt, Highway 3 - Hope to Princeton via Allison Pass into Tuesday for Fraser Canyon - south including Lytton, Similkameen, South Okanagan - including Penticton, Coquihalla Highway - Hope to Merritt, and possibly 20 centimetres for Highway 3 - Hope to Princeton via Allison Pass

There may be a slight reprieve of low wind chill values as a Pacific system approaches on Tuesday bringing more snow. However cold temperatures will return Tuesday night before rebounding on Friday.

Ensure that shelter is provided for pets and outdoor animals.
