a) – d) The fraction of heatwave days with more than 1 mm of precipitation, for winter (DJF), spring (MAM), summer (JJA), and autumn (SON; columns). e) – h) The fraction of non-heatwave days with more than 1 mm of precipitation. i) – l) The difference in the fraction of wet-days between heatwave and non-heatwave days. Blue indicates where heatwave days are more frequently wet than non-heatwave days, and red indicates where heatwave days are less frequently wet than non-heatwave days.
A map of 14,425 basins across North America from HYSETS, coloured according to the clusters defined by the basins’ heatwave-precipitation frequency curves. Basin colours and their corresponding cluster are defined by the colourbar (right). An inset of the west coast (left), with the inset area shown by the bounding box in the full map. White areas are those without basins in the HYSETS database.
A map of the Northeast USA showing the forecast risk of unhealthy heat for Tuesday, June 24. High risk extends from NYC to Raleigh to Indiana.

Maps of North America, showing how heatwave conditions are either wetter or drier than normal conditions. Results are shown in terms of both frequency of precipitation, and precipitation amount, for each season.
