Environment Canada yesterday issued a yellow advisory for freezing drizzle at 8:28pm EST Wednesday.
Roads, walkways, and other surfaces will likely become icy and slippery. There is risk of injury due to slips and falls, it said.
It forecast periods of freezing drizzle leading to minor ice build-up and icy surfaces. A brief period of thunderstorm freezing rain was also possible last night.
“As the main area of precipitation from today’s [Wednesday’s] system exits the region, a widespread area of freezing drizzle will linger into tonight. A developing area of thunderstorms is tracking across southwestern Ontario this evening and may result in brief periods of thunderstorm freezing rain,” said the weather agency.
