Heavy Rainfall Warning


Environment Canada has posted heavy rainfall warnings for Metro Montreal, and most of extreme southern Quebec. Further north across the central portion of the province snowfall warnings are posted. A potent storm system over Michigan is expected to move eastward into the province overnight tonight. A wide area of moderate to heavy precipitation is falling across Ontario this afternoon. The precipitation will edge into Quebec shortly. Despite the plus 5C reading at this hour some light ice pellets are falling in the city. This will rapidly change to rain with 30-40mm forecast in the next 24 hours. In addition to the rain very strong southeast winds will develop and gust over 60km/h. Further north across the northern Laurentians heavy snow is forecast with the potential for 15-30cm.

Further south across New York and Vermont, the big story will be the wind. High wind warnings are in effect across the spine of the Green Mountains and into the Adirondacks. Wind gusts of 40 to 60mph or close to 100km/h are expected. This storm has a trailing cold front that has a history of deadly severe weather. Over 15 people died yesterday as a result of tornadoes and severe thunderstorms that spread across Oklahoma, Arkansas, Mississippi, Alabama and Georgia. The severe weather has shifted east towards the Carolina's today.
