Storms prompt Flash Flood Emergency in central New York

Rainfall between 3 and 5 inches prompted a rare Flash Flood Emergency in Chenango County, New York, on Sunday. The heavy rain is flooding creeks and roadways. Local authorities report homes taking on water. 

ONEIDA COUNTY, N.Y. – Severe thunderstorms contributed to three deaths in central New York and dumped up to 5 inches of rain on Sunday, prompting a rare Flash Flood Emergency as floodwaters covered roads and entered homes. 

Storm reports from the National Weather Service office in Binghamton, New York, show Oneida County's emergency manager reported three deaths after severe storms knocked down multiple trees onto at least two separate structures near Clark Mills, New York, just before 4 a.m. ET on Sunday. 

FOX Weather has reached out to Oneida County officials to independently confirm these storm-related fatalities.

Oneida County officials said thunderstorms left more than 30,000 without power and caused significant damage in the towns of Kirkland, Lee, Westmoreland and Trenton. National Grid crews are working to restore power. 

"We are doing everything we can to respond quickly and safely to the damage left by these storms," Oneida County Executive Anthony J. Picente, Jr., said in a statement. "Our emergency teams are on the ground clearing roadways, coordinating with utility crews and assessing the needs of affected communities. I urge everyone to stay alert, avoid downed power lines and give our crews the space they need to do their work." 

The same storm system brought a deluge of rain to central New York throughout Sunday morning. 

Shortly before 9 a.m. ET, the NWS office in Binghamton issued a Flash Flood Emergency for Chenango County.
