Ottawa adds winter storm watch to weekend weather as Environment Canada predicts up to 40cm of snow

Ottawa is already under an extreme cold warning with temperatures dropping as low as -35°C with the wind chill.

Environment Canada has added a winter storm watch in addition to already issuing an extreme cold warning for Ottawa over the weekend.

The weather agency issued the winter storm watch on Saturday, Jan. 15, saying winter storm conditions are expected Sunday evening through Monday.

Heavy snowfall is forecast with snow accumulation reaching between 25 and 40 cm by Monday evening.

Snowfall peaks of two to five centimeters per hour are possible Monday morning.

Although the watch was issued for Ottawa, other watch regions include Simcoe-Caledonia-Haldimand, Niagara and much of eastern Ontario, including Kingston.

“There remains uncertainty about the exact path of the system, which will affect the location of the heaviest snow patch,” Environment Canada said. “Snowfall amounts are expected to decrease sharply along the western edge of the storm system. Local blowing snow is also possible Monday afternoon and evening with gusty north to northwest winds.

Avoid travel if possible, the weather agency added, as it should be dangerous due to reduced visibility in some places.

Surfaces such as highways, roads, sidewalks and parking lots can become icy and slippery.

There can also be a significant impact on rush hour traffic in urban areas.

Ottawa is also under an extreme cold warning with conditions dropping as low as -35C with the wind chill on Saturday morning.

After moderating on Saturday afternoon, extremely cold wind chill values ​​down to -35°C are again expected from Saturday evening to early Sunday morning.

Under these conditions, Environment Canada says frostbite can develop within minutes on exposed skin, especially with wind chill.
