KANSAS CITY, M.O.(WNAX)- The national Climate Prediction Center has issued a La Nina watch for later this year. Cooler than normal Pacific Ocean surface temperatures leads to the formation of a La Nina, which can cause cooler and wetter conditions in much of North America.

Doug Kluck, with the Central Region of the National Weather Service in Kansas City, says that would be back to back La Ninas.

Kluck says the last La Nina, which faded away this spring, didn’t have the normal impacts.

Kluck says the watch anticipates the formation of a La Nina by late fall into winter.
