(Radio Iowa) — Key state officials say Iowans who aren’t in a flood zone today should prepare for flooding. State Climatologist Justin Glisansays 2018 was the second-wettest year on ecord and the ground is saturated — creating concerns as the snow in the Dakotas and Minnesota melts and drains south. “If we get into a regime with active precipitation patterns, we could be in a very bad position,” Glisan says.

Glisan says forecast models indicate there will be “above average precipitation” in the weeks ahead. The 147 years of weather records for Iowa show the atmosphere and surface temperatures are warming and that means it’s more likely to rain, according to Glisan. “What we’re seeing over the past 30 years is that the intensity of precipitation events is increasing and we’re also seeing them lock into specific parts of the Midwest and even over Iowa,” Glisan says. “…You’re getting rainfall rates in which infrastructure can’t keep up.”

Glisan cites last summer’s flash flooding in central Iowa caused when as much as eight inches of rain fell in three hours. Joyce Flinn, director of Iowa Homeland Security and Emergency Management, says community leaders should consider how to protect key infrastructure, like drinking water plants, from flooding. “We’re focused on the Missouri River right now, but there are a lot of the interior rivers that are high as well and there’s the potential for flooding on the Mississippi, so we are reaching out to those folks,” Flinn says. “Mnay of them are taking those proactive measures because when you lose a water system, that’s hard to recover from quickly.”

Flood waters have swamped three southwest Iowa communities in the past week. Flinn and Glisan made their comments Friday, during a taping of the “Iowa Press” program.
