TUCSON, AZ (Tucson News Now) -
A strong El Niño is already in place this fall, and that could mean a wet winter for Arizona. The last strong El Niño was in 1997/98. Recently, NASA compared the two El Niño signals side-by-side.
In the image below the color red stretching across the ocean represents an El Niño. You can see this year's El Niño is even looking a little more impressive as of August 20 than the 1997 El Niño on the same day.
