| Maps are given showing expected precipitation probabilities in tercile classes. The maps indicate probabilities that seasonal precipitation will
fall into the wettest third of the years (top number), the middle third of years (middle number) or
the driest third of the years (bottom). An outlook of climatology "C"
(light grey) indicates equal probabilities in each class; i.e., there is no basis for favoring the forecast of any particular category. Areas marked "D" (dark grey)
experience a pronounced dry season during the forecast period, typically receiving less than 15% of their annual precipitation or less than 5 cm total during this
three-month period. Boundaries between sub-regions should be considered
transition zones, and their location considered to be only qualitatively
