Overview
- Environment Canada issued yellow snow squall and snowfall warnings for parts of Ontario including Sudbury, Ottawa North–Kanata–Orléans, and the London–Parkhill–eastern Middlesex area.
- Forecasters expect 10 to 20 centimetres of accumulation from Tuesday night into Wednesday as lake-effect bands redevelop in some zones.
- Sudbury’s squalls are paired with southwesterly wind gusts up to 60 km/h that will produce blowing snow and rapid visibility drops.
- In Ottawa, snow is forecast to begin Wednesday morning with winds up to 30 km/h and an evening low near minus 10 C.
- The London area also faces a yellow freezing drizzle advisory that could create hard-to-detect icy surfaces, with officials warning of hazardous travel, sudden near-zero visibility, and possible road closures under the new three-tier alert system.
