Extreme flooding targets Vermont as New York recovers from devastating rainfall

(NEW YORK) — A few moments after Idlewild Creek began to rise on Sunday, the first wave of murky water washed into the ground floor of Kristine Schmidt’s blue-and-white house.

Moments later, she saw her neighbors swept away in their SUV, Schmidt told ABC News on Monday. Fire trucks arrived and pulled their car out of the creek, she said.

As the floodwater receded from her home in Cornwall, New York, it left a trail of a thick mud in its wake. Outside her home, potted plants had been knocked over and grass had been uprooted. Inside, amid the ruins of her living room and kitchen, a bookshelf and fridge lay on their sides.

“We’re all heartbroken,” she said.

The flooding in Cornwall, in Orange County, came as heavy rain drenched much of the Mid-Atlantic and Northeast on Sunday, prompting flash flood alerts in parts of New York.

More than 8 inches of rain fell in just hours in some areas in the Hudson Valley and at least one person was killed in the storm in Orange County, New York.

Areas in New York counties including Orange, Putnam, Rockland and Westchester were under flash flood warnings into the early hours of Monday.

“Last night was complete chaos,” Orange County Executive Steve Neuhaus told ABC News’ “Good Morning America” on Monday.

Members of his staff were working to contact people throughout the county on Monday morning, he said, adding that roads and bridges were washed out by the storm. His staff was attempting to reopen “major arteries” throughout the area, he said.

Everyone who had reported an issue appeared to have been accounted for, “but there are some people who could have been swept away,” Neuhaus said.

There’s significant damage to homes, businesses and infrastructure in Orange County, New York Gov. Kathy Hochul said.

“Orange County experienced a 1-in-1,000-year weather event last night,” the governor tweeted Monday. “The rain has subsided, but the crisis is not over.”

Hochul warned, “New York State is facing simultaneous weather emergencies: Southern New York is recovering from last night’s damage. Heavy rain is impacting the Mid-Hudson, Capital Region, & North Country. A Flood Watch is in effect for most of Eastern New York through Tuesday night.”

“As ongoing extreme weather conditions continue in Northeast New York, the Lake Champlain region is at greatest risk for flash flooding,” Hochul said. “As we’ve seen, conditions can change in an instant. New Yorkers should take this seriously & prepare.”

The rain is continuing to push north on Monday, with flooding expected from upstate New York to Vermont to New Hampshire to Maine.

In Vermont, where a state of emergency is in effect, rare excessive rainfall and life-threatening flash flooding is expected. So far, 19 people have been rescued by boat and another 25 people have been evacuated, officials said.

Vermont Gov. Phil Scott said the state has not seen flooding like this since Hurricane Irene in 2011, and in some places, the flooding will surpass that.

“Flash flood warnings are in effect from the Massachusetts line to the Canadian border,” Vermont State Police said. “If you can, please stay home today. However, if floodwaters are approaching your home, leave immediately.”

Three to six inches of rain is expected for Vermont.

This is the first time a “high risk” has been issued for the Burlington, Vermont, area. The ground in this area is already very saturated due to receiving 300% of its normal rainfall over the last two weeks, so flooding could happen very easily.

FEMA Administrator Deanne Criswell said the agency is closely watching the situation.
