UPDATE 5:18 p.m. Wednesday: The funnel cloud weather advisory has ended for SD&G.
SD&G – Environment Canada says conditions are favourable today (Wednesday) for possible funnel clouds this afternoon across SD&G.
In fact, one was spotted near Rockland just after noon.
Funnel clouds are not tornadoes. They are caused by weak rotation in the cloud cover or from weak thunderstorms. “This weak rotation is normally not a danger near the ground,” the agency said.
But there is still a chance the rotation can get stronger and become a “weak landspout tornado.”
The landspout tornado can cause tree and roof damage.
The funnel cloud advisory comes on the heels of violent weather the Cornwall area experienced Tuesday when over 40 trees were toppled in what is believed to be a microburst from a thunderstorm.
