SOUTH DAKOTA(WNAX)- Combine an ongoing La Nina with a predicted active Atlantic Ocean hurricane season and it may translate to more rain in the Midwest later this summer.

Doug Kluck, Climate Services Director for the Central Region of the National Weather Service, says a La Nina often means more tropical activity.

A La Nina occurs when Pacific Ocean surface temperatures are below normal and it impacts weather in North America.

Kluck says in some past La Nina years, that moisture has streamed north into the central US.

The Climate Prediction Center has now issued guidance that indicates the La Nina may persist into a third year though next spring.
