AI less than zero indicates warmer and drier than normal.
AI greater than zero indicates cooler and wetter than normal.

(These statements apply to climate weeks 14 and after, which is most of the season, but weeks 11, 12, and 13 have negative weighting and thus an AI less (greater) than zero would indicate cooler and wetter (warmer and drier) than normal during this early part of the season).
