A relatively dry three week period in Brandon came crashing to an end on Sunday as a Severe Thunderstorm effecting much of Southwestern Manitoba rolled through the area, bringing heavy downpours, severe wind gusts and frequent lightning as its main threats along with hail that unofficially appeared to max out at marble size.
With dark clouds to the immediate West and Southwest of the City and the storm approaching, an elevated level of concern came about after televisions and some local mobile devices received an emergency alert notification of a Tornado Warning for the coverage area. That was followed just prior to 4:30pm with the activating of the City of Brandon’s Emergency Alert siren, sending residents to basements in caution.
With a Severe Thunderstorm Warning in place the first of the system’s rain began to fall at approximately 4:45pm. , By the time the storm approached Brandon, no Tornado Warning was in place for Brandon with ECCC.
The sky began to lighten just after 6:30pm, hinting that the worst may be over though ECCC radar showed the potential for more rain and storm activity into the evening. As of 6:40pm, unofficial rain gauge totals in the city hinted at the possibility that more than five inches had fallen up to that point. For those scoring at home, the record for June 28 going into today was 25.9mm set in 1952. ECCC will release presumably release official rainfall totals tomorrow.
