El Nino is back and it could very well end up being one of the stronger El Ninos we have seen in over a decade as we get into the late fall and winter months.

El Nino is defined as the warming of the sea surface temperatures in the equatorial part of the Pacific Ocean.

When the sea surface temperature anomalies run at or above 0. 5 degreesC for three consecutive months, then we officially enter into an El Nino phase.
