A combination of a cold winter, rapid snowmelt due to mild air and heavy rain from a massive "bomb cyclone," and other factors led to some of the worst flooding on record in Nebraska, Iowa, Minnesota and Wisconsin, and is beginning to affect downstream states. The extreme nature of the floods — which have overtaken large parts of Offutt Air Force Base, where America's nuclear forces are coordinated — is best seen from high above.

Why it matters: The floods have wiped out farms, killed an unknown amount of livestock, marooned entire towns and destroyed large infrastructure as rivers have risen, sending surges of water and chunks of ice churning downstream. While waters are receding in many locations in Nebraska, flooding is occurring further southeast into the Mississippi River Valley.

Much of the Midwest continued to be inundated with historic flooding Monday night.

The latest: The National Weather Service issued flood warnings and advisories for the Plains, the Mississippi Valley, and parts of the Ohio Valley region.

The big picture: Vice President Mike Pence would survey the damage from the "terrible flooding" in Nebraska Tuesday, White House Press Secretary Sarah Huckabee Sanders said.

• Two-thirds of the town of Hamburg, just east of the Missouri river, was "lost,"Iowa Gov. Kim Reynolds said, according to NBC News, and 42 of Iowa's counties had declared emergencies.
• Mills County Emergency Management Director Larry Hurst told the Des Moines Register nobody knew when the water would subside, as it continued to smash through a levee break near the point where the  Platte and Missouri rivers converge at Plattsmouth Toll Bridge. "I've got water all the way to the Loess Hills, he said. "There's water on this entire basin."

Why it matters: At least three people have died in ferocious flooding in the regions around the Platte and Missouri rivers, caused by melting snow and heavy rain from the "Bomb Cyclone" in the Midwest. Nebraska Gov. Pete Ricketts said it's the worst flooding in the state for 50 years. Dams have failed, levees breached and other infrastructure stripped away as raging floodwaters and chunks of ice move downstream.

Though the official death toll is 84, more than 1,000 people are believed to have died after a cyclone hit Mozambique, the country's president said Monday.

Details: Over 100,000 people in Mozambique were injured after Cyclone Idai hit the coastal nation with the strength of a Category 3 storm, before moving inland toward Zimbabwe and Malawi, CNN reports. Mozambique’s economy relies heavily on agricultural exports, which will be heavily impacted by the flooding.

Melting snow and heavy rain from the "Bomb Cyclone" in the Midwest has caused historic flooding from the Platte and Missouri rivers.

Why it matters: Nebraska Gov. Pete Ricketts said it's the worst flooding the state has experienced in 50 years, with at least two flood-related fatalities this week. Dams have failed, levees breached and other infrastructure stripped away as raging floodwaters and chunks of ice move downstream.

At least three people have died after a "bomb cyclone" dumped rain on the frozen Plains late last week, causing record flooding from ice jams and snowmelt along the Missouri and Platte rivers. Dams have been virtually obliterated, levees have failed and entire communities marooned.

The latest: Flood warnings remained in place Sunday evening across eastern Nebraska, parts of Iowa and southern Wisconsin. The National Weather Service forecast the areas would be subjected to major flooding possibly until Wednesday. The National Guard warned had earlier told Nebraskans the flooding could last for "quite some time."

Details: Nebraska Gov. Pete Ricketts said it was the worst flooding in Nebraska for at least 50 years. The National Weather Service warned hazardous flooding would likely last throughout the weekend in the state, as well as in south and west central Iowa. The worst affected area would be around the Platte and Missouri rivers.
