CARL AZUZ: The governor of the US state of Nebraska says nearly every region of his state is dealing¹ with historic flooding.

This is all part of the bombogenesis or bomb cyclone² that blew east off the Colorado Rockies last week. It blasted that state's capital and many other parts of the central US with blizzard³ conditions and nearly hurricane force winds. Heavy rains and flooding were all part of it. And that c?ontinues to be a problem in Nebraska, as piles and drifts of snow melt swell⁴ rivers and flood communities.

Nebraska's Emergency Management Agency says records have been broken in at least 17 locations and that more of that is expected. The water has never been measured this high along the Missouri, Platte, and Elkhorn rivers. 53 counties, 54 cities, and two Native American tribes have declared emergencies. Most of the areas affected⁵ by the bomb cyclone are expected to have calmer weather this week. But as the snow continues to melt and the rainwater runs down hills in the creeks⁶ and rivers, the flooding threat isn't over.

KAYLEE HARTUNG: Bridges destroyed, highways washed out, cars and cattle stranded⁷ — this is the aftermath of a bomb cyclone. The powerful weather system slammed the Midwest with hurricane-like winds and blizzard conditions last week, leaving drowning rains and flooding in its wake. And after heavy snowfall this winter, natural snowmelt is making bad conditions worse.

In Wisconsin, Darlington officials say the city hasn't seen this much flooding in more than 25 years.

Fremont, Nebraska, home to more than 26,000 people, became an island when roadways in and out of town flooded Friday. Nebraska's governor touring the damage in his state.

GOVERNOR PETE RICKETTS: This has probably been, you know, the most severe widespread flooding we've had, as far as the parts of the state that's been impacted, we've had the last half century.

KAYLEE HARTUNG: Nebraska rescue teams have been pulling trapped residents out of floodwaters since Thursday, and forecasters caution more snowmelt is on the way. So the worst flooding may be yet to come.
