FOR THE NORTHWEST TERRITORIES  
ISSUED BY ENVIRONMENT CANADA  
AT 2:21 P.M. MDT MONDAY 3 JUNE 2019.  
 
DISCUSSION.  
 
PROBABLE TORNADO REPORTED NEAR FORT SMITH ON SUNDAY, JUNE 2ND  
 
AT APPROXIMATELY 4:00 PM MDT ON SUNDAY, JUNE 2ND A PROBABLE TORNADO  
WAS OBSERVED IN FORT SMITH, NWT. ENVIRONMENT AND CLIMATE CHANGE  
CANADA'S PRAIRIE AND ARCTIC STORM PREDICTION CENTRE (PASPC) RECEIVED  
MULTIPLE REPORTS OF A FUNNEL CLOUD AND PHOTOS OF PROBABLE TORNADIC  
DAMAGE IN FORT SMITH. DAMAGE REPORTS INCLUDED DOWNED TREES, SEVERAL  
HOMES THAT LOST ROOFING MATERIAL, AND AT LEAST TWO SHEDS THAT WERE  
OVERTURNED OR DISPLACED. ENVIRONMENT AND CLIMATE CHANGE CANADA'S  
ASSESSMENT IS THAT THIS WAS A PROBABLE TORNADO, WITH A PRELIMINARY  
RATING OF EF-1. A WIND ENGINEER WITH WESTERN UNIVERSITY'S NORTHERN  
TORNADOES PROJECT IS EN ROUTE TO FORT SMITH TO CONDUCT A DAMAGE  
SURVEY THAT WILL BE USED TO CONFIRM THESE FINDINGS. THIS WOULD BE  
ONLY THE 4TH TORNADO CONFIRMED NORTH OF 60 DEGREES LATITUDE IN  
CANADA.  
 
THIS WAS LIKELY A LANDSPOUT TORNADO THAT WAS GENERATED BY ROTATION  
UNDER A RAPIDLY GROWING THUNDERSTORM. LANDSPOUT TORNADOES DO NOT  
USUALLY CAUSE SIGNIFICANT DAMAGE BUT CAN STILL BE DANGEROUS AS THEY  
CAN TOPPLE TREES, DAMAGE ROOFS, OR TOSS DEBRIS A SHORT DISTANCE.  
 
PASPC METEOROLOGISTS ARE ACTIVELY SEEKING PICTURES OF THE TORNADO OR  
DAMAGE IT MAY HAVE CAUSED. SHOULD YOU HAVE ANY INFORMATION REGARDING  
THIS EVENT, OR TO REPORT SEVERE WEATHER AT ANY TIME, PLEASE CALL  
1-800-239-0484, SEND AN EMAIL TO NTSTORM(AT)CANADA.CA, OR TWEET TO  
(HASH)NTSTORM.  
 
NOTE THAT THIS STORM ASSESSMENT IS CONSIDERED PRELIMINARY AND MAY BE  
CHANGED IF MORE INFORMATION BECOMES AVAILABLE.
