Environment Canada says they’re harmless to those on the ground; funnel clouds have been spotted in the north of Barrie.
The national weather service says these types of funnel clouds are borne of rapidly growing clouds or weak thunderstorms, causing a weak rotation that is normally not a danger near the ground.
Environment Canada does point out there is a chance the rotation of the funnel cloud could intensify and become a weak landspout tornado.
“Treat any funnel cloud sighting seriously.” reads an advisory from Environment Canada. “Should a funnel cloud develop nearby, prepare to take shelter. These funnel clouds usually appear with little or no warning.”
