Two-thirds of the continental United States will be a frozen ice box Tuesday, as the so-called polar vortex of frigid arctic air spins across the U.S. Midwest, clips the Great Lakes, the Ohio Valley and pushes on into New England.

And the sub-zero cold and bitter winds will stick around for a couple of days, possibly bringing dozens of record lows with a life-threatening freeze before dissipating by the weekend, the National Weather Service reported (NWS).

The polar vortex is a mass of freezing air that normally spins around the North Pole, but has slipped southward and swirled into the United States, forecasters said.

When Hurricane Harvey left so much of Houston underwater, it highlighted a problem that’s been getting worse for years: Harris County’s existing floodplain maps just don’t work.

In the year since the historic storm, flood control officials have promised to change that, and they already had plans to redo the maps, but new data on the geography of the area and the amount of rainfall forecasters expect in the future means the new maps could look drastically different.

It’s crucial the maps are done right, as people are using the maps, meant to set flood insurance premiums, for more than they are intended . . .

About 3.4 million chickens and turkeys and 5,500 hogs have been killed in flooding from Florence as rising North Carolina rivers swamped dozens of farm buildings where the animals were being raised for market, according to state officials.

The N.C. Department of Agriculture issued the livestock mortality totals Tuesday, as major flooding is continuing after the slow-moving storm's drenching rains. Sixteen North Carolina rivers were at major flood stage Tuesday, with an additional three forecasted to peak by Thursday.
