2013 Ontario Tornado Statistics

[on_wx]

Environment Canada confirms an average of 12 tornadoes per year in Ontario. Some years can have 20-30 tornadoes, others have less than 10. As of August 1, 2013 a total of 11 tornadoes have been confirmed which have mostly been weak tornadoes which are fairly typical to the province. Though, we often have F2 tornadoes a couple times per year, and F3+ are rare but do happen from time to time.

Thanks for sharing, hadn't seen the Casselman video.

Pretty lame tornado season IMO. With the exception of the Kenilworth tornado, everything was out in the boonies and pretty unchaseable in terms of terrain. Not a lot of action over the nice flat SW Ontario farm country although I did catch that amazing wall cloud back on May 22nd.

Usually there's a shot at a tornado or two in August but the pattern looks pretty dull.

Came face-to-face with the EF0 in Orleans (east end of Ottawa), took some nice pics and a video.  That was fun.

Updated ON tornado totals for 1950-Aug 3 2013. Unknown injury numbers for 2013. I will update Fujita rating numbers shortly. Incomplete injury numbers for 2009, and a lot of missing information for decades past. Total injuries could be over 1,000, and fatality numbers are likely missing.

 

 

*63 yr, not 62.

Severe weather outbreak today across Southern Ontario sparked dozens of tornado warnings and at least three tornadoes touched down near Arthur, Orillia, and Carnarvon. Other tornadoes will likely be confirmed.

 

Tornado east of Arthur, Ontario was on the ground for 10+ minutes.

No major damage or casualty reports as of right now. This information can be slow to trickle through in Ontario.

WEATHER SUMMARY FOR ALL OF SOUTHERN ONTARIO AND THE  

NATIONAL CAPITAL REGION ISSUED BY ENVIRONMENT CANADA  

AT 5:20 P.M. EDT THURSDAY 8 AUGUST 2013.  

  

TWELFTH, THIRTEENTH AND FOURTEENTH TORNADOES OF THE SEASON  

CONFIRMED.  

  

A LINE OF SEVERE THUNDERSTORMS DEVELOPED LATE WEDNESDAY AFTERNOON  

FROM THE ARTHUR AREA TO ORILLIA TO NORTH OF MINDEN.  THESE  

THUNDERSTORMS TRACKED EASTWARD AND MAINTAINED THEIR STRENGTH AS THEY  

PASSED OVER THE HALIBURTON AREA AND PORTIONS OF EASTERN ONTARIO.  

THROUGH THE SUPPORT OF OUR CANWARN STORM SPOTTER NETWORK, A NUMBER OF  

MEDIA PARTNERS, LOCAL GOVERNMENT OFFICIALS AND THE GENERAL PUBLIC,  

NUMEROUS PHOTOS AND VIDEOS HAVE BEEN PROVIDED TO ENVIRONMENT CANADA  

OVER THE LAST NUMBER OF HOURS. MANY OF THESE PHOTOS AND VIDEOS SHOW  

FUNNEL CLOUDS, WATERSPOUTS AND TORNADOES OCCURING OVER DIFFERENT  

AREAS IN SOUTHCENTRAL ONTARIO. FORTUNATELY AS OF LATE THURSDAY  

AFTERNOON, ENVIRONMENT CANADA IS NOT AWARE OF SIGNIFICANT DAMAGE  

BEING CAUSED BY THESE STORMS.  

AN ENVIRONMENT CANADA STORM INVESTIGATOR TRAVELLED THE AREA BETWEEN  

ARTHUR AND GRAND VALLEY TODAY AND CONFIRMED THAT AN ENHANCED FUJITA  

SCALE ZERO (EF-0) TORNADO MOVED THROUGH THAT AREA WEDNESDAY  

AFTERNOON. THE ENHANCED FUJITA SCALE ESTIMATES THE WIND ASSOCIATED  

WITH A TORNADO BY THE DAMAGE IT CAUSES AND GOES FROM ZERO (WEAKEST)  

TO 5 (STRONGEST). WINDS IN AN EF-0 TORNADO ARE BETWEEN 90 AND 130  

KM/H. THE TORNADO WAS 4.5 KILOMETRES LONG AND 100 METRES WIDE.  

WITH A COMBINATION OF EYEWITNESS ACCOUNTS, IMAGES OF LOCALIZED DAMAGE  

AND OTHER PHOTOGRAPHIC EVIDENCE, AN EF-0 TORNADO WAS CONFIRMED IN THE  

ORILLIA AREA. EYEWITNESS ACCOUNTS, LOCALIZED DAMAGE AND PHOTGRAPHIC  

EVIDENCE WERE ALSO USED TO CONFIRM A TORNADO IN THE CARNARVON AREA  

NORTH OF MINDEN. THIS TORNADO HAS NOT YET BEEN RATED PENDING A DAMAGE  

INVESTIGATION THAT WILL TAKE PLACE ON FRIDAY.  

EYEWITNESS AND PHOTOGRAPHIC EVIDENCE WERE ALSO INSTRUMENTAL IN  

CONFIRMING A WATERSPOUT OVER HEAD LAKE IN THE NORTHERN KAWARTHA LAKES  

AREA WEDNESDAY AFTERNOON. AT THIS POINT IT APPEARS THE WATERSPOUT  

STAYED OVER THE LAKE AND DID NOT COME ONSHORE. IF EVIDENCE COMES TO  

LIGHT THAT THERE WAS A TRACK OF DAMAGE ONSHORE FROM THIS EVENT THEN  

IT WOULD ALSO BE CATEGORIZED AS A TORNADO.  

ENVIRONMENT CANADA PERSONNEL CONTINUE TO INVESTIGATE THE NUMEROUS  

STORMS FROM WEDNESDAY AFTERNOON AND EVENING AND AS NEW INFORMATION  

BECOMES AVAILABLE THIS STATEMENT WILL BE UPDATED ACCORDINGLY.  

IN ONTARIO 12 TORNADOES ARE VERIFIED ON AVERAGE EACH YEAR. THE TOTAL  

FOR THIS SEASON NOW STANDS AT 14. THE SUMMER SEVERE WEATHER SEASON IN  

ONTARIO NORMALLY RUNS FROM LATE APRIL UNTIL EARLY OCTOBER.  

  

TIME AND LOCATION                         EVENT DESCRIPTION  

  

4:30 P.M. ORILLIA                         CONFIRMED TORNADO (EF-0)  

  

5:00 P.M. CARNARVON                       CONFIRMED TORNADO  

  

5:50 P.M. ARTHUR-GRAND VALLEY             CONFIRMED TORNADO (EF-0)
