Heavy Rain Warning

Very heavy rain continues to fall in the Montreal area. When I got home from work I had 46mm in the gauge or just under 2 inches here on Ile Perrot, that was at 7pm. I just went out to check on it at 9pm and there is an unbelievable 80mm now or just over three inches since it began early this morning. The culprit is strong low pressure off the east coast of the US pumping in a long plume of moisture from the tropics. The storm is producing flooding from southern Quebec all the way into the Carolina's at this hour. The heavy rain will continue overnight with at least another 20mm forecast. Radar is showing heavy rain across the metro region with some thunderstorms across upstate New York. Other rainfall totals as of 8pm were 51.6mm at St. Anicet, 54.7mm at Brockville and 31.6mm at Kemptville.

A flood watch is in effect for all of Vermont and New York. There are also flood warnings in effect for several regions including Clinton, Franklin and Essex Counties in upstate New York. Flooding is occurring along the Ausable River in northern New York. High winds are also beginning to affect southern portions of Vermont and New York. Wind gusts to 50mph may occur.
