A powerful storm that struck Cape Breton in September 2026 has caused widespread flooding and significant damage, making it an event residents are unlikely to forget. The slow-moving system began bringing intense rainfall from the south on Friday and particularly affected Richmond County.
Some areas experienced extremely heavy rainfall, with rates reaching 20 to 30 millimetres per hour. Sampsonville received around 150 millimetres in only six hours, while Eskasoni recorded 71 millimetres within three hours.
The storm continued to draw moisture from the east and northeast, producing further heavy rain on Saturday across Victoria and Cape Breton counties and the Sydney area. More rain through Sunday night and Monday pushed localized totals in parts of Victoria County above 250 and even 300 millimetres, causing severe flooding and infrastructure damage.
Weather models had successfully anticipated the storm and predicted widespread rainfall of 80 to 150 millimetres, with some forecasts indicating totals above 200 millimetres in Victoria County. However, predicting extremely localized rainfall is difficult. The models failed to foresee the exceptionally intense rainfall of 20 to 30 millimetres per hour recorded around Bras d’Or Lake on Friday night.
