Monster El Nino May Be Brewing, Experts Say

Ready for a ’90s El Nino flashback?

Researchers are keeping a close eye on a giant pool of abnormally warm water in the Pacific Ocean that some think could trigger another El Niño of epic proportions if it rises to the surface, sending weather patterns into a tizzy around the world.

That could mean heavy rains in drought-stricken California, dry weather across the Midwest and East Coast, and parched landscapes in Australia and South Africa while it pours in South America. The phenomenon is linked to the periodic warming of surface waters in the eastern tropical Pacific Ocean.
