Historic New England flooding

The month of March has produced some of the heaviest rainfall in recent memory across New England and the middle Atlantic states. Yesterday was no different as nearly 7 inches of rain fell in Rhode Island and Massachusetts producing record breaking - life threatening floods. Flooding of this magnitude has not been seen since the early 1950's when back to back hurricanes, Connie and Donna flooded the region. The Pawtuxet River is cresting at nearly 9 feet over flood stage and has forced closure of Interstate 95 near Warwick. Major flooding has forced thousands out of their homes with rivers continuing to rise in Rhode Island, Massachusetts and Connecticut. The map below shows how much rain fell during the most recent storms. The heaviest rain remained just to our south along the US border. Some regions have had almost 2 feet or rain in March.

Montreal received about 25mm of rain over the last week to bring our monthly total to only 59.2mm (2.2 inches). That amount fell on only 6 days of the month. We normally have precipitation on 13 days during March. The incredible stats are our daily maximum temperatures and snowfall. The average maximum was 7.7C compared to a normal of 2.2C. The mean average was a warm 3.3 compared to the normal of -2.3C. We recorded only 1.4cm of snow officially at Dorval, or less than one inch. Unbelievable for a "winter" month. We are looking at potential record highs on both Friday and Saturday with temperatures reaching 25C.
