It was the first real storm of the season for southern Manitoba.
According to Environment Canada at 3:10 p.m. on Monday, weather radar indicated a rotating thunderstorm just west of Morris moving eastwards at 50 km/h.
Storm spotters said a wall cloud accompanied the storm, and doppler radar indicated the system could produce a tornado.
At one point, tornado warnings were in effect for some parts of the region. Severe thunderstorm watches and warnings were also issued.
Very large hail was in the forecast and the south end of Winnipeg reportedly saw tennis ball sized hail. Damaging wind gusts were also part of the storm system.
The same system then marched through northwestern Ontario during the evening hours Monday. Environment Canada issued a tornado warning for Fort Frances and Kenora. A Red Alert was also issued by Emergency Management Ontario, encouraging residents to take precaution and stay indoors.
There were funnel cloud reports in the area, but no touch downs have been confirmed. Frequent lightning, heavy downpours and damaging winds were also reported as these storms rolled through.
