A TORNADO TOUCHED DOWN JUST WEST OF LONG PLAIN FIRST NATION, MB

THE TORNADO THEN MOVED EASTWARD ACROSS THE ASSINIBOINE RIVER WHERE  
IT THEN MOVED THROUGH THE SOUTHERN PART OF THE NEW ROSEDALE  
HUTTERITE COLONY. SOME GRAIN BINS WERE DAMAGED ALONG WITH FARM SHEDS  
BEING COMPLETELY DESTROYED.  
 
THE TORNADO THEN MOVED EAST OF THE COLONY WHERE IT DEPOSITED DEBRIS  
OVER FARM FIELDS. IT CONTINUED EASTWARD BEFORE LIFTING NEAR HIGHWAY  
240 AROUND 7:10 PM.  
 
THE TORNADO WAS ESTIMATED TO BE MOVING AT 30-50 KM/H TO THE EAST AND  
WAS ON THE GROUND FOR APPROXIMATELY 9 KILOMETRES. BASED UPON THE  
DAMAGE SURVEYED IN BOTH LONG PLAIN FIRST NATION AND THE NEW ROSEDALE  
HUTTERITE COLONY, THIS TORNADO HAS A PRELIMINARY RATING OF EF-1  
ACROSS THE TWO AREAS AND THUS ESTIMATED WIND SPEEDS OF 150 KM/H.  
 
THIS WAS AN EXCEPTIONAL STORM. NOT ONLY WAS THERE DAMAGE ASSOCIATED  
WITH A TORNADO, THERE WAS ALSO A SWATH 10-20 KM WIDE OF  
STRAIGHT-LINE WIND DAMAGE AFFECTING A SIGNIFICANT PART OF THE  
REGION, INCLUDING MUCH OF THE LONG PLAIN COMMUNITY. THESE DAMAGING  
WINDS WERE IN THE 100-120 KM/H RANGE AND THERE WERE SOME GUSTS UP TO  
140 KM/H REPORTED IN THE AREA.

OF TORNADOES. A SEVERE THUNDERSTORM WARNING WAS ISSUED AT 6:19 PM  
CDT AND WAS UPGRADED TO A TORNADO WARNING AT 6:56 PM CDT BASED ON  
DOPPLER RADAR DATA. AT 7:01 PM CDT A REPORT OF A TORNADO WAS  
RECEIVED BY ENVIRONMENT AND CLIMATE CHANGE CANADA.  
 
DUE TO THE COMPLEX NATURE OF THIS EVENT, THIS IS ONLY A PRELIMINARY  
RATING FOR THE TORNADO. ADDITIONAL EXPERTS AND EYEWITNESSES ARE  
BEING CONSULTED. SOME EVIDENCE MAY POINT TO STRONGER TORNADIC WINDS,  
THEREFORE THE RATING MAY BE SUBJECT TO CHANGE.
