An El Nino is forecast to continue over the next several months.
El Nino occurs when a large area of warmer than average water builds up in the eastern Pacific Ocean near the equator.
According to NOAA, El Nino returned this winter and strengthened during February and March as above average sea surface temperatures increased across the Pacific Ocean near the equator.
Typically, El Nino brings wetter conditions across the southern half of the United States and milder conditions along the northern tier of the country.
Right now, weak El Nino conditions are expected to continue through spring and into summer.
The Climate Prediction Center will issue their next El Nino outlook later this month.
