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.
