Weather: Why we should worry about a few more millimetres of rain

As our wet days get wetter, we should be concerned that even a small increase in precipitation risks exceeding critical thresholds and causing our protection systems to collapse


The showers began in the wee hours of the morning of April 3, then settled into a steady rain that continued until the end of the day. By then, much of central Ontario had been soaked with up to 45 millimetres of rain – almost two-thirds of the total monthly rainfall April normally brings. Accompanying winds gusted to speeds as high as 70 kilometres per hour. It was one very dull, wet and blustery day!
