Alerts for: Greater Sudbury and vicinity


3:52 PM EST Wednesday 07 December 2016
Snow squall warning in effect for:

  • Greater Sudbury and vicinity

Snow squalls are occurring. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow combined with blowing snow, and snow will quickly accumulate.

Snow squalls to continue through Thursday morning.

Local snowfall amounts of 10 to 15 cm per 12 hours are likely in the strongest snow squalls. The strongest snow squall currently extends from western Manitoulin Island northeast towards Sudbury. The snow squall will begin to shift south tonight, moving out of the region Thursday morning.

Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Travel is expected to be hazardous due to reduced visibility in some locations. Consider postponing non-essential travel until conditions improve.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to or tweet reports to #ONStorm.
