The IRI outlook for seasonal total precipitation for June-August 2015 issued in the third week of May. Green areas indicate places with an increased chance for above normal rainfall, while yellow or brown areas show an increased chance for below normal rainfall. “Normal” is defined by the rainfall that was observed in middle one-third of the cases during the 30-year period of 1981-2010. The color shading shows the probability for above-normal (if green) or below normal (if yellow or brown) rainfall. White areas indicate no forecast direction, which implies an equal (33.3%) probability for any of the three possibilities (below normal, near normal or above normal). Pink indicates regions having their climatological dry season (less than 30 mm during the season). Map by Fiona Martin, based on IRI data.
