Earlier in the day, Japan's weather bureau forecast the chances of an El Nino through the northern hemisphere winter at 90%.
The World Meterological Organization had in May warned that the weather pattern could contribute to rising global temperatures.
"In July, El Niño continued as indicated by above-average sea surface temperatures across the equatorial Pacific Ocean," the CPC said.
Given recent developments, forecasters are more confident in a "strong" El Nino event, with roughly two in three odds of temperatures rising by about 1.5 degrees Celsius (2.7 degrees Fahrenheit) or more in November-January, it added.
It was also expected to bring drier weather across West Africa, South-East Asia and northern South America, and wetter conditions to southern South America in the second half of the year.
