Environment Canada has issued a caution warning predicting 3 to 15 cm of snow in the Ottawa region on Sunday. The snowfall is expected to begin Sunday morning and continue through the night.
Earlier forecasts had anticipated a maximum accumulation of about 5 cm by Saturday afternoon. However, the latest update from Environment Canada increased the expected snowfall to between 3 and 15 cm.
The snowfall is attributed to a low-pressure system moving into the area.
