Weather Advisory: Conditions favourable for funnel clouds niagara

The Niagara Story Place sponsored by Calhoun

Environment Canada issued a weather advisory for favourable conditions for the formation of funnel clouds today. 

Issued at 11:52 Thursday 07 September 2017


- sightings already reported in Niagara along with water spouts over Lake Erie. 

Conditions will be favourable for the development of funnel clouds today.

Scattered thunderstorms are expected this afternoon and early evening across Southern Ontario.

Some of the thunderstorms will bring dime sized hail, wind gusts to 70 km/h and frequent lightning.

Funnel clouds may also make a brief appearance this afternoon in this unseasonably cool and unstable air mass.

Thunderstorms are expected to dissipate this evening.


These types of funnel clouds are generated by weak rotation under rapidly growing clouds or weak thunderstorms. This weak rotation is normally not a danger near the ground. However, there is a chance that this rotation could intensify and become a weak landspout tornado.

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

This message could be about your business. Ask us.

  • Thanks Debi. I follow Connecting Niagara on Twitter and Facebook as well. It's nice to have a site that promotes local events and organizations. We appreciate the support and promotion of our event.
