Reduced visibility on roads north of London

Midwestern Ontario is being battered with snow, with heavy winds, and blowing snow creating dicey driving conditions.

A burst of heavy snowfall is expected to push snow squalls south, with stationary snow bands setting up this afternoon and high accumulations overnight. This could result in up to 60 centimetres by Saturday evening. Environment Canada says higher amounts are possible.

Friday night will see the heaviest snowfall. Winds will gust up to 60 km/h, significantly reducing visibility.

Weather conditions will vary greatly from region to region, with changes from clear skies to heavy snow within mere kilometers.

Road closures are possible, and drivers are asked to adjust their driving according to the conditions. Unnecessary travel should be avoided.
