So the fact that it\u2019s almost there before we even get into the summer like that, that\u2019s pretty meaningful.\u201d<\/p>\n Some forecasters are already calling this a rare \u2018super\u2019 El Ni\u00f1o that could smatter records.<\/b><\/p>\n \u201cThis developing El Ni\u00f1o has the potential to become one of the strongest in decades and could rival some of the most intense events observed in modern records,\u201d said Paul Pastelok, Accuweather Lead Long-Range Expert, in a news release.<\/p>\n Here\u2019s what you need to know about El Ni\u00f1o and its potential effects on North Carolina.<\/p>\n Trade winds \u2014 the strong winds that helped sailors navigate the world\u2019s oceans \u2014 blow across the Pacific Ocean from South America towards Asia, bringing with it warmer water that\u2019s replaced by colder, deeper ocean water.<\/p>\n Those strong winds weaken during an El Ni\u00f1o. Warm water pushes toward the Americas, and the cold water isn\u2019t replaced off the coast.<\/p>\n \u201cWhen you look out across the Pacific Ocean, every two to three years, we tend to see the water shift from being warmer than normal to cooler than normal,\u201d Davis said. \u201cAnd when you have a very large body of water that is consistently warmer or cooler than normal, that starts to have impacts on large scale weather patterns.\u201d<\/p>\n The effect of this El Ni\u00f1o likely won\u2019t be felt until later this year and into 2027.<\/p>\n El Ni\u00f1os tend to bring wetter winters to the Carolinas, and drier and warmer air across the northern parts of the United States.<\/p>\n Three past North Carolina El Ni\u00f1o winters \u2014 in 1997-1998, 2009-2010 and 2015-2016 \u2014 rank among the state\u2019s top ten wettest on record, according to the North Carolina State Climate Office.<\/a><\/p>\n The origins of the term \u2018super\u2019 El Ni\u00f1o likely has more to do with algorithms than science.<\/p>\n \u201cThese are headline writers being very creative because you get terms like \u2018super\u2019 El Ni\u00f1o,\u201d Davis said. \u201cI\u2019ve also seen a Jurassic El Ni\u00f1o and a Godzilla El Ni\u00f1o. There is no science behind any of those terms, but they\u2019re very catchy, and they\u2019re very attention grabbing.\u201d<\/p>\n The Climate Prediction Center forecasts the strength probabilities of El Ni\u00f1o as \u201cweak,\u201d \u201cmoderate,\u201d \u201cstrong\u201d and \u201cvery strong.\u201d El Ni\u00f1o officially begins when a key portion of the Pacific Ocean near the equator is 0.5 degrees Celsius warmer than normal.<\/p>\n \u201cWhile confidence in the occurrence of El Ni\u00f1o has increased since last month, there is still substantial uncertainty in the peak strength of El Ni\u00f1o,\u201d according to this week\u2019s Climate Prediction Center\u2019s update<\/a>.<\/p>\n That data shows a 37% chance of a very strong El Ni\u00f1o in November, December and January timeframe. El Ni\u00f1o reaches the \u201cvery strong\u201d category when it\u2019s 2 degrees Celsius warmer than normal.<\/p>\n Read more NC high school baseball coach collapses before team\u2019s playoff game. What we know<\/a><\/p>\n \u201cStronger events do not always mean bigger weather and climate impacts,\u201d according to the Climate Prediction Center. \u201cStronger events can make it more likely that certain impacts could occur.\u201d<\/p>\n Think about a house of cards, and how easily it can topple down with a quick gust.<\/p>\n A stronger and earlier El Ni\u00f1o brings more warm water, strengthening the jetstream, or air currents, moving toward the Atlantic Ocean.<\/p>\n \u201cThese upper level winds blow right across the tropical Atlantic, the same environment where tropical storms and hurricanes are formed,\u201d Davis said. \u201cAs we get closer to the peak of hurricane season, those strong winds may actually hamper some of the tropical activity.\u201d<\/p>\n But an earlier El Ni\u00f1o, with its warming water, could lead to earlier storms during the hurricane season, which runs June 1 through November 1.<\/p>\n \u201cKnowing that the water is already fairly warm out there, it\u2019s possible we could see more early season activity and, historically, when we see tropical storms forming in June, July and even early August, the coast of North Carolina is a pretty common spot for those types of systems to form because that\u2019s where the warmest water is.\u201d<\/p>\n Some early hurricane forecasts<\/a> are predicting average-to-below-average seasons this year, through the National Weather Service will release its report next week.<\/p>\n If this year\u2019s hurricane season is below average with fewer or weaker storms, an El Ni\u00f1o could offset the usual amount of rain.<\/p>\n \u201cWe don\u2019t like to wish for a hurricane,\u201d Davis said. \u201cBut we can sort of have our fingers crossed for a decent tropical storm in the next couple of months (for the state\u2019s drought).\u201d<\/p>\n About 95% of the state is in extreme drought, with some recent soaking rain enough to get rid of the worst drought ratings near Charlotte. But several areas including in the Triangle, Triad and mountains are still facing significant rainfall shortages with some cities implementing water restrictions.<\/p>\n \u201cWe\u2019re counting on this El Ni\u00f1o to eventually bring us some wetter weather, some better rainfall chances, but it may take until the end of the year once we get into the cooler season,\u201d Davis said.<\/p>\n El Ni\u00f1os used to mean North Carolina would get the cold and<\/i> wet stuff during the winter months.<\/p>\n Now, it\u2019s mostly the wet stuff.<\/p>\n \u201cFor folks who are used to associating El Ni\u00f1o with snow, that\u2019s one of the adjustments that we\u2019re having to learn with a warming climate,\u201d Davis said. \u201cWith the sort of warm air that can come in from a strong El Nino pattern, snow is far from a guarantee.<\/b> We can have a very wet winter and not see a flake of snow this year.\u201d<\/p>\n Five of the seven El Ni\u00f1o events prior to 1990 were cooler than the 20th-century average, while the five events after were warmer, according to state data.<\/a> That includes the winter of 2015-16, one of the last strong El Ni\u00f1o events in the state.<\/p>\n Rain was near constant with the state getting three to four inches of precipitation a week in December 2015, the wettest December on record.<\/p>\n Questions about life in North Carolina?
