NOAA Climate Prediction Center products read daily and served together: the Oceanic Niño Index for every three-month season since 1950 with El Niño and La Niña episodes under NOAA's five-season rule, the weekly Niño-1+2, 3, 3.4 and 4 indices since 1981, the monthly ENSO alert status and synopsis, and the official probability and strength outlooks for the next nine seasons. PRISM archives every monthly outlook by issue month so a forecast can be read against what followed.

An AI analyst whose answers are retrieved from PRISM's live datasets and report archive at the moment you ask — never from memory. Every figure carries a linked citation to its exact source, every answer ends with a “Reproduce this” trail of the queries it ran, and when the data can't answer, it says so.
