Atlanta — The flooding that devastated the US Midwest is likely to last into next week, as rain and melted snow flow into Kansas, Missouri and Mississippi, the National Weather Service said.

Floods driven by melting snow in the Dakotas will persist even as Nebraska and Iowa dig out from storms that have killed four people, left one missing and caused more than $1bn in damage to crops, livestock and roads.

“It’s already not looking good downstream for the middle and lower Mississippi and Missouri Rivers into Kansas, Mississippi and Missouri,” Bob Oravec, a meteorologist with the National Weather Service’s (NWS) weather prediction centre, said early on Wednesday.

The floodwaters have inundated a swathe of Iowa and Nebraska along the Missouri River, North America’s longest. Half of Iowa’s 99 counties have declared states of emergency.

“That snow pack is still there and it’s going to keep melting, and that’s bad news,” Oravec said. About 2.5cm of rain is predicted for Saturday in the region, Oravec said. “It’s not a lot, but any precipitation is bad right now.”

US vice-president Mike Pence toured some of Nebraska on Tuesday and promised to help expedite federal help to the region. Nebraska, Iowa and Wisconsin and Mississippi all declared states of emergency after the floods, which stemmed from a powerful winter hurricane last week. The flooding killed livestock, destroyed grains and soybeans in storage and cut off access to farms because of road and rail damage.

Authorities said they have rescued nearly 300 people in Nebraska alone, with some rivers continuing to rise. Rescuers could be seen in boats pulling pets from flooded homes. Some roadways crumbled to rubble and sections of others were submerged. In Hamburg, Iowa, floodwaters covered buildings.

$1bn in damage

Nebraska officials estimate flood damage for the state’s agriculture at more than $1bn so far, according to Craig Head, vice-president of issue management at the Nebraska Farm Bureau. Head said that is likely to grow as floodwaters recede.

“It’s really too early to know for sure how bad this is going to get. But one thing we do know: it’s catastrophic for farmers,” said Matt Perdue, government relations director for the National Farmers Union. “We’re hoping it’s only $1bn, but that’s only a hope.”

Nebraska officials estimate the floods have also caused $553m in damage to public infrastructure and other assets, and $89m to privately owned assets, according to the state’s emergency management agency on Tuesday.

The water covered about a third of Offutt Air Force Base near Omaha, Nebraska, home to the US Strategic Command, whose responsibilities include defending against and responding to nuclear attacks.

The US army corps of engineers is distributing 400,000 sandbags to operators of 12 levees along the Missouri River in Missouri and Kansas that are threatened by flooding, the corps said in a news release on Tuesday.

Roads leading to the Nebraska public power district’s Cooper nuclear plant near Brownville were engulfed by floodwaters from the Missouri, but the facility was still operating safely at full power on Tuesday. The plant operator was flying staff members and supplies to the plant by helicopter, power district spokeserson Mark Becker said.
