Tornado kills Canadian motorist in northwest ND; passenger hospitalized

By The Associated Press (CP) 1 hour ago

BISMARCK, N.D. A tornado touched down in northwest North Dakota, tossing a car about 400 metres and killing its 51-year-old Canadian driver.

The driver, from St. Brieux, Saskatchewan, was travelling on U.S. Highway 52 about 10 kilometres east of Bowbells when the car was tossed into a nearby field, the Highway Patrol said. The four-door sedan came to rest on its roof about 10:30 p.m. Thursday.

The driver was pronounced dead at a Kenmare hospital.

A 19-year-old St. Brieux man who was a passenger in the vehicle was taken to a Minot hospital with what were described as severe injuries.

The tornado also destroyed a home and damaged another, along with some outbuildings, the National Weather Service said.

Radar Images
Shown below are the radar images from the Minot Air Force Base WSR-88D radar located near Deering, North Dakota. Within the reflectivity images, a distinct "Hook Echo" can be seen on radar protruding out of the southern portion of the storm near Bowbells. This signature is an indication of rain or hail being wrapped into the parent low level circulation of a possible tornado. The storm relative motion images show how precipition is moving within the thunderstorm. Shades of green and blue indicate motion towards the radar, and shades of red indicate motion away from the radar. Notice the tight couplet of bright greens, and blues next net bright red near Bowbells. This indicates fast moving air towards the radar and away from the radar over a very short distance, signifying rapid rotation. The red boxes in the images are the outlines of the Tornado Warnings issued by the National Weather Service in Bismarck, and the yellow boxes are the outlines of the Severe Thunderstorm Warnings. 937 PM CDT Reflectivity
