Alerts for: Niagara


11:34 PM EST Thursday 14 December 2017
Snow squall watch in effect for:

  • Niagara Falls - Welland - Southern Niagara Region

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

Conditions are expected to become favourable for snow squalls from Lake Erie to come ashore between Dunnville and Fort Erie beginning late Friday morning.

Local snowfall amounts of 15 cm are possible under the strongest and most persistent snow squalls Friday.

Motorists should be prepared for hazardous winter driving conditions due to sudden very low visibility in bursts of heavy snow and blowing snow.

Snow squalls will weaken into flurries Friday evening.

Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow.

Snow squall watches are issued when conditions are favourable for the formation of bands of snow that could produce intense accumulating snow or near zero visibilities.

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