Environment Canada has issued a special weather statement for the Ottawa area as 10 to 15 centimetres of snow is expected to hit the city on Thursday and Friday.
The snow is forecast to begin falling on Thursday afternoon, continuing throughout the night into most of the day on Friday.
Many parts of southern and eastern Ontario may receive 15 to 25 centimetres of snow from the storm before it ends Friday night, according to Environment Canada.
Not only will it be snowy, but also bitterly cold. A Thursday high of minus 15 is expected to feel like minus 30 with the wind chill.
Ottawa Public Health has issued their fourth Frostbite Advisory this week for Thursday, urging those spending time outdoors to dress in layers and cover exposed skin, which can freeze in 10 minutes.
OPH says there is a risk of hypothermia for people who stay exposed to cold temperatures for a long period without proper winter clothing.
Environment Canada advises Ottawa morning commuters that travelling conditions will be difficult on Friday due to the snowfall.
