A Winter weather travel advisory is in effect as snow continues to fall in Niagara.
Environment Canada says snow will continue through tonight and into early Friday morning with 5-10 centimetres expected.
Most of the snow will fall tonight.
Officials say poor winter driving conditions are expected and untreated roads may become snow covered and slippery.
Environment Canada is warning us that the snowfall may have major impacts on the commute this evening and possibly impact the Friday morning commute as well.
Motorists should plan for extra time to reach their destination.
This is the largest snowfall event so far this season, and the first significant snowfall for many parts of the Golden Horseshoe.
The snow will become mixed with rain on Friday as temperatures edge above the zero degree mark.
This snow is associated with a deepening low pressure system moving along the Eastern Seaboard of the United States.
