Catastrophic flooding turned neighborhood streets into raging waterways as videos show floodwater submerging vehicles and closing roads, sparking the National Weather Service (NWS) to issue an "exceedingly rare" flash flood emergency for parts of New York.
The warning is only issued when "extremely" heavy rain is leading to a severe threat to human life and "catastrophic damage" from a flash flood, the NWS says on its website.
After hours of nonstop downpour, the heavy rain produced "life-threatening flash flooding" on Sunday across New York's Hudson Valley region with Twitter users in Rockland and Orange counties sharing videos and photos of the severe weather. Governor Kathy Hochul and New York State Police (NYSP) urged people to stay home amid the dangerous conditions.

Cheryl L. Boujnida, spokesperson for the U.S. Military Academy at West Point, told Newsweek in an email Monday morning that the Army Garrison West Point team is "working around the clock" to restore capabilities and determine the scope of damage.
"The U.S. Military Academy is assessing the extent of the damage caused by flash flooding in Orange County yesterday," Boujnida said. "Local and state emergency responders are on site and providing the West Point community with steadfast support. As local internet capabilities are intermittent, West Point will provide updates as soon as additional information becomes available."
Newsweek reached out via email and Twitter to the representatives for the NWS and Highland Falls Police Department.
Steven Nevel, NYSP public information officer, told Newsweek in an email on Sunday evening that state police are asking the public to avoid the Palisades Interstate Parkway in Rockland County due to heavy flooding.
"There are numerous motorists stranded in Rockland County," Nevel said to Newsweek. "State Police along with local fire departments and EMS personnel are utilizing personal and equipment to assist this motorists and get them to safety as fast as possible."

— Blaise Gomez (@BlaiseGomez12) July 9, 2023While providing an update on the flooding during a Spectrum News appearance on Sunday, Hochul said she wanted New York residents to be prepared, warning "this is a serious event."
"My biggest concern is the fact that most people's lives that are lost during a flood event occur because they're in their vehicles - not in their homes, but in their vehicles, the governor said. "And I want people to be very cautious about not going into a road that's closed or if you see any running water."
Hochul said emergency crews are "on the ground" and ready to respond but noted that they likely won't be able to assess the damage until possibly Monday morning at the earliest.
She advised New Yorkers to have flashlights, first aid, food, water, and medicine "so you do not have to leave your house once this becomes a very intense storm in the overnight hours."
