Much is currently being made about the very strong El Nino, which some have labelled as a "Godzilla El Nino". The concern is the impact of this on our upcoming winter season.

The featured chart displays a monthly time series of El Nino 3.4 index and average Iowa monthly temperature departures. The current El Nino is the strongest since 1997.
