Environment Canada said the winter weather is caused by a low pressure system that is moving over Southern BC Sunday.

Drivers heading onto the roads are being reminded to prepare for quickly changing weather conditions. Those getting behind the wheel should remember to maintain a safe following distance and drive for the conditions they are facing.

Those heading onto the highways are encouraged to check DriveBC for up-to-date road conditions.
