Inundated: Another 10-20 cm of snow possible for Ontario cities

Closures are racking up across parts of southern Ontario, as another round of powerful snow squalls hit the traditional snowbelt regions off Lake Huron and Georgian Bay. Snow squall warnings remain in effect.

"Travel is expected to be hazardous due to reduced visibility in some locations. Rapidly accumulating snow could make travel difficult over some locations. Road closures are possible," warned Environment and Climate Change Canada (ECCC) in the snow squall warning issued for the London area. Warnings also continue for Barrie and Collingwood, and other locales around southern Georgian Bay and Lake Huron.

An additional 5-15+ cm could fall throughout the day on Wednesday, adding to the already hefty totals that have accumulated since the start of the week. In the London area, 25 cm had already fallen by early Wednesday.

If snow squalls become stationary over one area, locally heavier amounts are possible.
