Motorists in the Thunder Bay area should prepare for challenging road conditions on Friday.

Environment Canada has issued a travel advisory, forecasting heavy snow from this morning through the night.

Accumulations are expected to range between 10 to 15 centimetres before the snowfall eases into flurries early tomorrow.

Strong north winds may cause reduced visibility, making travel potentially hazardous.

Drivers are advised to adjust their travel plans and exercise caution on the roads.
