Alerts for: Niagara


3:45 PM EDT Monday 15 October 2018
Frost advisory in effect for:

  • Niagara Falls - Welland - Southern Niagara Region
  • St. Catharines - Grimsby - Northern Niagara Region

Frost may damage some crops in frost-prone areas.

Temperatures tonight will fall to near or below freezing for several hours, even in regions where winds don't diminish to light.

Hence tender plants will be subject to a general freeze tonight.

Temperatures immediately along the shorelines of the Great Lakes may hover just above the zero degree mark thanks to the relatively mild waters of the lakes.

Temperatures will rise above the freezing mark after sunrise Tuesday morning.

Cover up plants, especially those in frost-prone areas.

Frost advisories are issued when temperatures are expected to reach the freezing mark during the growing season, leading to potential damage and destruction to plants and crops.

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