"I expect that this fall, given how active the Pacific is, and how warm it is, we are going to see a lot of that moisture move in to help promote fall rain fall here," Cerveny said.
While El Niño could be a soaker for Arizona and help alleviate some of the California drought, Oregon and Washington won't be so lucky.
"El Niño for the northwest part of the country, they're probably going to be drought conditions," Cerveny said.
While we could expect tropical moisture with warmer temperatures in Arizona, the El Niño of 1998 proved to be a big snow maker for the higher elevations.
According to the National Weather Service, Flagstaff received 120 inches of snow that winter. Arizona Snowbowl Ski Resort reported 330 inches, which could mean an economic boom is ahead for ski season this winter.
Experts say El Niño should continue through at least winter of 2016.
