Significant ice accumulation can result from freezing rain, with general amounts of five to 15 mm and amounts in excess of 20 mm possible. Environment Canada warns that utility outages, slippery surfaces, and broken tree branches from ice build-up are a possibility.
A break in the freezing rain is expected for most areas late in the day on Saturday into Saturday night before a second round of freezing rain begins.
Environment Canada believes the likelihood of an increase in a widespread, prolonged freezing rain event is occurring over portions of southern Ontario. The swath of maximum ice accretion is still uncertain but confidence is highest for central and eastern Ontario areas between Parry Sound and Kingston. Environment Canada will issue warnings as the event draws nearer.
