El Niño has formed in the Pacific, and forecasters say it could become one of the strongest events on record.
El Niño is a natural warming pattern in the Pacific Ocean that can affect weather around the world. This cycle may increase the risk of extreme heat, floods, droughts, wildfires, and other costly weather disruptions.
NOAA says there is a 63% chance this El Niño could become intense enough to rank among the largest events in the historical record going back to 1950.
The potential impact is not limited to weather. Severe climate events can affect agriculture, energy demand, insurance costs, supply chains, transportation, and local economies.
For households and businesses, El Niño is as much an economic story as an environmental one.
U.S. meteorologists say an El Nino has formed. That's the natural warming of parts of the Pacific that changes weather around the globe.
