The El Nino phenomenon typically means colder and wetter than normal conditions in Oklahoma from the following October to March, said Gary McManus, associate state climatologist.

La Nina, which occurs due to cooler than normal water temperatures and is the opposite of El Nino, was in effect during the last two winters.
