Environment Canada has issued a winter weather travel advisory for Hamilton, Niagara, and Halton regions.

The weather agency says a band of heavy snow moving over Southwestern Ontario is expected to bring five to 15 centimetres of snow Friday morning.

The heavy snow has already caused several problems for motorists during their morning commute.

Hey #HamOnt, hopefully this is the last snowfall for the season. Either way, let's take our time on the roads and leave space between you and other vehicles. pic.twitter.com/uyuRLtGmVc
