While spring is now only a few short weeks away, it seems Canada's weather is still well and truly in winter mode. After a weekend of pleasant temperatures, Environment Canada has issued an Ottawa winter storm warning, and this could be the worst one yet. Locals can expect up to 40 cm of snow by Thursday morning, combined with freezing rain and poor travelling conditions. Welcome back, winter!\nJust when you thought the worst of this season’s weather was over, it seems that Ottawa is in for another wallop of snow and slush.\nAccording to a new warning from Environment Canada, Ottawans should be prepared for what could be the biggest snowstorm of the year so far.\nWith upwards of 40 cm predicted in some areas, it’s going to be a very snowy end to the month. Light blizzards are expected to begin on Wednesday afternoon, becoming heavy snowfall as evening sets in.\nThis will continue uninterrupted throughout the night. By Thursday morning, residents of the capital city should expect anywhere between 20 and 40 cm of snow in their driveways.\nDue to the dangerous travel conditions, Environment Canada suggests postponing all non-essential travel, as low visibility and quickly accumulating snow is likely to make road conditions dangerous.\n...at least there's no #FrostbiteAdvisory, right?If you're commuting tomorrow, please stay safe. Road & sidewalk conditions will be affected by this storm. Drivers: if you're able, be sure to have at least 1/2 tank of gas before starting your commute. #Plan #Prepare #BeAware https://t.co/DClFKQdLxB— Ottawa Public Health (@ottawahealth) February 25, 2020\nSimilar conditions are expected across Ontario, with heavy snow also falling in Quebec.\nIn Lake Ontario and St. Lawrence, there’s also the chance of some freezing rain.\nAccording to Environment Canada’s predictions, this could actually end up being the biggest snowfall of the year so far in Ottawa.\nAs there could be up to 15 cm of snow on Wednesday night, combined with an extra 20 cm or more by Thursday morning, there could be upwards of 40 cm total before the system moves out of the region.\nSo far this year, the largest single-day snowfall was just less than 30 cm on February 7.\nThat said, it’s not all bad news. Despite the snowy conditions and the possible disruptions to travel services, temperatures will stay relatively mild.\nIn fact, they shouldn’t be much lower than zero in most areas.\nAdditionally, with the countdown to spring now officially on, the end of Ottawa's winter season is finally in sight.\nGood morning! A winter storm watch is on for Ottawa tonight into tmrw with 20-40 cms of snow expected. pic.twitter.com/vgSePnfLYR— Robyn Bresnahan (@RobynBresnahan) February 26, 2020\nYou can keep up with the latest local winter storm information by visiting the Environment Canada website.\nStay safe Ottawa!
