NASHVILLE, Tenn. (WSMV) - On Thursday, NOAA’s Climate Prediction Center officially declared that El Niño conditions have developed in the tropical Pacific Ocean and issued an El Niño Advisory, signaling that the climate pattern is now underway and expected to strengthen in the coming months. The announcement comes as headlines warning about a possible “Godzilla,” “mega,” or “super” El Niño continue to spread online. While those names grab attention, they aren’t official scientific classifications.
