Environment Canada has just issued a special weather advisory that conditions will be favourable for the development of funnel clouds in the greater Kawarthas region on Saturday (July 11).

The advisory includes Peterborough, Kawartha Lakes, Northumberland, Hastings, and Haliburton.

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.

Environment Canada issued the advisory after receiving multiple reports of funnel clouds and waterspouts late on Saturday morning.

Treat any funnel cloud sighting seriously. Should a funnel cloud develop nearby, prepare to take shelter. These funnel clouds usually appear with little or no warning.
