Vast areas of the United States are at risk of flooding This kind of spring, even as Nebraska in addition to some other Midwestern states are already reeling through record-breaking late-winter floods, federal scientists said on Thursday.

Nearly two-thirds of the lower 48 states will have an elevated risk of some flooding through at This kind of point until May, in addition to 25 states could experience “major or moderate flooding,” according to the National Oceanic in addition to Atmospheric Administration.

“The flooding This kind of year could be worse than anything we’ve seen in recent years, even worse than the historic floods of 1993 in addition to 2011,” said Mary C. Erickson, deputy director of the National Weather Service, in a conference call with reporters. The major flooding This kind of month in Nebraska, Minnesota, Iowa in addition to elsewhere will be “a preview of what we expect throughout the rest of the spring,” she said.

Some 13 million people could be exposed to major flooding, generating This kind of a “potentially unprecedented” flood season, said Edward Clark, director of NOAA’s National Water Center.

in addition to much of the United States east of the Mississippi River, as well as parts of California in addition to Nevada — in total, areas home to more than 0 million people — could see at least some flooding inside spring, the scientists said.

Above-average rainfall of which scientists expect for the spring, along with melting snow, would likely add to the flooding in addition to extend This kind of through the central in addition to southern United States. NOAA identified the greatest risks for moderate to major flooding inside upper, middle in addition to lower Mississippi River basins, the Red River of the North, the Great Lakes, in addition to the eastern Missouri River, lower Ohio River, lower Cumberland River in addition to Tennessee River basins.

Andrew Dessler, a professor of atmospheric sciences at Texas A&M University, said of which understanding the role of climate change in weather events like the Nebraska floods required applying the tools of a growing field known as attribution science. “Without doing the analysis, you don’t know what role climate change played,” he said. “Certainly, floods happened before climate change.”

However, he added, heavier rainfall events are among the most common conditions associated with climate change. Humans have loaded so much planet-warming carbon dioxide into the atmosphere of which “the starting assumption has to be of which climate change will be affecting everything” to some extent, he said.

“The real question isn’t, ‘will be climate change playing a role?’” Dr. Dessler said. “This kind of’s, ‘How big a role will be climate change playing, in addition to what will be the role?’”

The National Weather Service describes moderate flooding as involving some inundation of structures in addition to roads near streams, with some evacuations; major flooding involves extensive inundation of structures in addition to roads in addition to significant evacuations.

By comparing This kind of year’s potential flooding to the seasons of 1993 in addition to 2011, Ms. Erickson was citing some of the worst weather disasters the United States has faced since the Great Mississippi Flood of 1927.

The 1993 flood inside Midwest killed 50 people in addition to caused $15 billion in damages; a reporter for The brand-new York Times called This kind of “a watery rampage by nature like no some other.”

inside 2011 floods, the Army Corps of Engineers took the extraordinary measure of blowing up 11,000 feet of Mississippi River levee to let water flow into the Birds Point floodway in Missouri, saving the little Illinois town of Cairo although inundating more than 100,000 acres of farmland in addition to homes.
