AMES, I.A.(WNAX)- The Climate Prediction Center has issued an “El Nino” watch for the possible development of the climate driver this summer.
Doug Kluck, Central Region Climate Service Director for the National Weather Service, says the El Nino would come after three years of a La Nina.
An El Nino occurs when Pacific Ocean surface temperatures rise above normal.
Kluck says weather patterns change under an El Nino.
Kluck says the El Nino is expected to develop rapidly this summer.
