Forecasters have stated that El Nino is arriving on the scene with the promise of new weather extremes brought about by warmer sea temperatures. For several years La Nina, which worsened Atlantic hurricanes and Western droughts, eased some of the worst temperature increases. A La Nina pattern has been described as a seesaw effect between La Nina and El Nino where El Nino usually brings a quieter hurricane season in the Atlantic and more hurricane activity in the Pacific. In the US, the change to El Nino promises some relief by lowering the risk of hurricanes in the East and drought in the West. El Nino’s warmer water temperatures can push the Pacific jet stream south resulting in dryer and warmer than usual areas in the northern US and Canada. In contrast, the US Gulf Coast and the Southeast are wetter than usual and have increased flooding. There is a 62% chance that El Nino will develop during the May-July period, increasing to over an 80% chance of El Nino by autumn.
