El Niño is expected to become one of the strongest climate events in more than seven decades, according to the report from the Climate Prediction Center.
The agency said there is an 81 percent chance the phenomenon will reach very strong levels after unusually warm sea surface temperatures spread across the central and eastern equatorial Pacific.
The report said the developing weather pattern has already prompted AccuWeather to lower its Atlantic hurricane season outlook to between eight and 14 named storms.
Stronger wind shear associated with El Niño is expected to disrupt tropical storm development across the Caribbean.
The Climate Prediction Center said there is only a 3 percent chance conditions will return to normal by early spring, with a 97 percent probability that El Niño will persist into early spring 2027.
