Freezing rain possible late this afternoon and evening. What: Locally icy and slippery conditions. Up to 2 mm of ice accretion or build-up possible. When: Late this afternoon and evening. Additional information: Precipitation is forecast to begin as snow or rain but may transition to a period of freezing rain before ending later this evening or overnight. Areas south of Highway 401 are likely to receive little to no icing as temperatures are expected to remain just above the freezing mark. Roads and walkways may become icy and slippery. Be very careful if walking or driving. ### Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@ec.gc.ca or post reports on X using #ONStorm.
