Canadian precipitation anomaly 2017

Spring 2017 turned out to be extremely wet in Eastern Canada with floodings in Ontario and Quebec. This positive Canadian precipitation anomaly has been forecast by some of our  climate forecasts – the ones started in March 2017 for the MAM (March, April, May) season with 40-85% probability for a wet season (see probability forecast map below). These maps show the forecast probability for a negative (blue) anomaly, normal climatic conditions or positive (red) anomaly. Without the forecast the probability for a negative anomaly, normal climatic conditions or positive anomaly is 33,3% each.
