Freezing rain expected Wednesday. What: Freezing rain with ice accretion of 4 to 8 mm on some surfaces. When: Wednesday morning through Wednesday evening.

Easterly winds gusting 50 to 60 km/h may exacerbate any tree damage.

For locations over the Dundalk Highlands and Niagara Escarpment, freezing rain may linger into early Wednesday evening.

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.
