Big thunderstorms sweep Montreal

Slow moving thunderstorms Tuesday evening dropped nearly 50mm of rain in less than 1 hour on portions of Montreal including Montreal North and Anjou. Houses were flooded and some roads closed including Highway 25. (Radio-Canada)

A late evening cold front crossed Montreal and southern Quebec on Tuesday with thunderstorms. Some of the storms produced flash flooding in parts of the city especially north of Montreal island. Here on L'Ile Perrot I only recorded a few millimeters of rain as the bulk of the activity passed north or south of my location. For whatever reason this has been the typical storm path all summer long. The front has ushered in some cool, fall like temperatures with current readings at 14C (56F). We are looking at cloudy skies today with the threat of some showers and even an isolated thunderstorm this morning. The activity will taper off as the day moves along. It will clear out tonight and be chilly with lows near 10C (50F). The balance of the week into the weekend looks spectacular with sunshine and temperatures from 24 to 28C by Sunday. Even the start of next week looks sunny and warm at this time.

The tropics are heating up as we approach the peak period of hurricane season. Forecasters at the National Hurricane Center are watching two areas of interest in the far eastern Caribbean and also the southern Gulf of Mexico. The disturbance in the Gulf could become tropical storm Erin within the next 48 hours.
