El Niño is officially here and "could lead to new records," NOAA says
El Niño's return could bring much more rain to Southern California later this year and drier conditions in the Pacific Northwest.

El Niño has officially made its way back after its years-long hiatus. NOAA announced on Thursday that the climate pattern system is expected to strengthen over the next several months.
The natural climate system comes as the Pacific Ocean experiences "warmer-than-average" surface temperatures. When that happens — every two to seven year — the system returns, generally spawning more rainfall in South America, winter storms in the U.S. West and South and droughts across Asia.
Either of these strengths typically result in "wetter-than-average" conditions from Southern California through the Gulf Coast, and "drier-than-average" conditions from the Pacific Northwest to the Ohio Valley, according to the National Weather Service.
So, El Nino is back. This could also affect the hurricane season for the Atlantic.
Such impacts could be harsh on California, which spent the first part of this year battling heavy rains and snow that flooded vast areas of the state. The dry conditions could also be worrisome for the Pacific Northwest, as dry weather is one of the factors that can lead to the beginning and spreading of wildfires.
El Niño's return also influences the 2023 Atlantic Hurricane season. NOAA says that the system's influence on oceans and atmosphere suppresses hurricane development in the Atlantic, while increasing hurricane activity in the Pacific, where surface temperatures have warmed.
So, possibly fewer hurricanes in the Atlantic and more in the Pacific.
