Discussion.

A frontal wave brought the first bout of snow to southern Manitoba 
over the weekend. The most significant snowfall amounts were 
observed in southwestern Manitoba. The early onset of snow resulted 
in widespread power outages for portions of southwestern Manitoba as 
the heavy wet snow fell on trees with remaining foliage. 

Snowfall measurements are a challenge during this time of year due 
to the wet nature of the snow and the melting that occurs throughout 
the day. Amounts below are an approximation. 

The following is a summary of snowfall amounts received by 
Environment Canada. Snowfall amounts are reported in centimetres 
(cm). 

Carberry: 5-10

Environment and Climate Change Canada confirms two tornadoes and a 
downburst in Eastern Ontario on Friday, September 21. 

A cold front tracked over Southern Ontario Friday afternoon and 
evening resulting in severe thunderstorms which produced two 
tornadoes and two downbursts. 

One severe thunderstorm produced a tornado that tracked over 
Kinburn, Dunrobin and Gatineau between approximately 4:40 pm and 
5:20 pm. This tornado damaged or destroyed numerous buildings, 
overturned vehicles and snapped many trees and hydro poles. There 
were also reports of multiple injuries including several people that 
were critically injured. Preliminary assessment of the damage 
indicates that this was a high end EF-3 tornado with wind speeds up 
to 265 km/h. 

A second severe thunderstorm produced a tornado in the neighbourhood 
of Arlington Woods in Ottawa near 6:00 pm. This tornado 
significantly damaged buildings and snapped many trees and hydro 
poles. Preliminary assessment of the damage indicates that this was 
a high end EF-2 tornado with wind speeds up to 220 km/h. 

Another severe thunderstorm produced a downburst in Calabogie near 
4:00 pm. Several houses have roof damage and many trees were snapped 
and uprooted. Winds associated with this downburst are estimated to 
be up to 175 km/h. 

Yet another area of damage from a severe thunderstorm was 
investigated at Sharbot Lake. A downburst with maximum winds of 
about 110 km/h knocked down many trees in the area. 

Environment and Climate Change Canada continues to conduct damage 
surveys to determine the exact track of these tornadoes. 

Any reports of damage can be sent to Environment and Climate Change 
Canada by emailing ONStorm@canada.ca or tweeting reports using
