00:00A Super El Nino is building in the Pacific, and it could reshape winter across the U.S.
00:05Forecasters at the Climate Prediction Center put the odds of a very strong event above 83 percent.
00:11Ocean temperatures in the eastern Pacific are running more than 4 degrees Celsius above normal.
00:16During El Nino, trade winds weaken and warm water slides east toward the Americas.
00:21That pushes the Pacific jet stream farther south.
00:24The result is often a wetter winter across the southern U.S. and the Gulf Coast.
00:28Meanwhile, the northern U.S. and Canada tend to run warmer and drier.
00:33In the desert southwest, the outlook leans wetter than normal from December to February.
00:38Offshore, less cold, nutrient-rich water rises, so there's less plankton for fish.
00:43Warmer water can even draw tuna farther north than usual.
00:46For many places, this winter may look very different.
