Discussion.

Southwestern and Central Ontario experienced strong storms during
the afternoon and evening hours on Wednesday. At approximately 4:20
PM Wednesday afternoon, a tornado occurred over Lake Simcoe near
Georgina Island. Tornadoes that occur over bodies of water are known
as waterspouts. This particular waterspout had the capability to
move inland and do damage but to this point in time, no damage has
been reported in that area.

At approximately 7:00 PM on Wednesday, a tornado occurred just to
the north of Lucan in Middlesex County. Environment Canada received
a number of reports through social media of this event and the
damage that ensued. Engineers from Western University in London
conducted a damage survey and concluded that this was an Enhanced
Fujita Scale 0 (EF0) tornado with peak winds of 130 km/h. The length
of the damage path was 5 km and the maximum width was 170 metres.
The tornado uprooted some trees and overturned some trailers on a
farm property.

At approximately 8:20 PM on Wednesday, the same storm cell that
spawned the Lucan tornado generated a possible tornado in the Drumbo
area. Environment Canada has received images of a funnel cloud in
this area. At this time, there is no evidence that a tornado
occurred and caused damage. The investigation into this event
continues.

Those who may have spotted funnel clouds or tornadoes from
Wednesday's storms or experienced notable storm damage, would be
welcome to send their reports to
