Forget the fake caravans. This is what is really approaching the US from the South

Concern mounts over slow-moving, planetary-scale ‘Kelvin’ wave heading for California
The ocean phenomenon could raise sea levels by up to a foot as El Niño keeps warm water trapped along the coast
Concerns are mounting about an ocean phenomenon known as a Kelvin wave that could raise sea levels along the California coastline by up to a foot, as scientists say El Niño is supercharging the threat of storm surges and flooding in the coming months.
As an incredibly strong El Niño continues to develop in the Pacific, the phenomenon brings with it a strange shift in the ocean. The Kelvin wave phenomenon is created when trade winds that usually blow from South America towards Asia die down or reverse in El Niño years, setting off a massive, slow-moving slosh of water.
Kelvin waves are not like crashing waves at the beach. They are planetary in scale, spanning thousands of miles. And when a Kelvin wave kicks off, it brings with it an untold amount of warm water that slowly moves from the western Pacific, along the equator, towards South, Central and North America.
“You can follow them along … we see the higher sea levels along the equator, and when the wave reaches the coast of South America, it cannot continue to go eastward,” Severine Fournier, a research scientist studying ocean circulation at Nasa’s Jet Propulsion Laboratory, said. “So it goes north and south.”
One such wave hit the northern tip of South America in late August and has begun moving up towards the west coast of the US. That wave could reach California shores within days, and when it does, ocean scientists say it may raise sea levels by up to a foot for months as El Niño lingers and keeps that warm water trapped along the coast.
