MADISON, Wis. -

Recent data from the National Centers for Environmental Information says Wisconsin's average rainfall this summer is among the highest ever.

Wisconsin Public Radio reports that about 16 inches of rain fell statewide from June to August, which is about 4 inches above average. State Climatology Office director John Young says that makes this summer the fourth wettest on record.

The northern part of the state experienced heavy flooding this summer that caused millions of dollars in damage.

Young attributes the increase in heavy rains to an increase in humidity. He says the state may experience more major flooding since wetter summers are expected to happen more often.
