El Niño's Potential Impact on Global and U.S. Weather Patterns

The World Meteorological Organization has warned that El Niño is on the way, with warmer sea temperatures promising new weather extremes. El Niño usually brings a quieter Atlantic hurricane season and more hurricane activity in the Pacific, while La Niña does the opposite. El Niño's warmer waters can also push the Pacific jet stream south, making areas in the northern US and Canada dryer and warmer than usual. La Niña said farewell in March, and there's a 62% chance that El Niño will develop during the May–July period, and more than 80% chance of El Niño by the fall.
