The summer of wild weather continues.
The remnants of Hurricane Ida brought heavy winds and dumped record levels of rain to the East Coast Wednesday into Thursday. It's also being blamed for the death of at least seven people in New York City, and three people in New Jersey, Pennsylvania, and Maryland.
The New York Police Department says one of the youngest flooding victims was two-years-old.
Floodwaters halted road, train, and air traffic in New York and New Jersey. The rain in New York City was so heavy that for the first time the city was under a flash-flood emergency, the most serious rainfall scenario.
States of emergency were declared in New York City, New York state and New Jersey due to the storms.
"We're enduring an historic weather event tonight with record breaking rain across the city, brutal flooding and dangerous conditions on our roads," New York City Mayor Bill de Blasio tweeted.
Rainfall in New York City makes history
The rain fell particularly hard and fast Wednesday evening.
A new record rainfall of 3.15 inches fell in Central Park in one hour, according to the National Weather Service. This level surpasses the 1.94 inches that fell in one hour during Tropical Storm Henri last month, which at the time, was thought to be the most ever recorded in the park.
Between 6 and 10 inches of rain fell over the course of several hours.
Waist-level floodwaters caused significant travel delays throughout the city. Most of the city's subway lines had to be shut down, leaving commuters stranded and needing to be rescued by the fire department.
The fast-moving storm quickly became deadly overnight. Throughout Wednesday night, police responded to calls of flooding at homes across the city.
In Brooklyn, police found the body of a 66-year-old man at his home.
In the Forest Hills neighborhood of Queens, police said they entered a house to find a 48-year-old woman unresponsive. She was transferred to Forest Hills Hospital where she was later pronounced dead.
Elsewhere in Queens, police discovered the bodies of a 50-year-old man, a 48-year-old woman, and a 2-year-old boy, also at a residence.
And in the Jamaica neighborhood of Queens, police came across a 45-year-old woman and a 22-year-old man at a house. The man was pronounced dead at the scene. The woman was transferred to Queens General Hospital and pronounced dead there.
Police are still investigating the cause of each of these deaths. The identities of the victims were not immediately disclosed.
Air travel was also halted due to the storm. New York City airports LaGuardia and JFK reported temporary flight disruptions.
Authorities pleaded with travelers not to attempt to drive through flooded roadways, but the New York City Fire Department reported needing to rescue several motorists. To prevent further issues for emergency responders, the city issued a travel ban on all non-essential vehicles from New York City streets and highways until 5 a.m. Thursday.
Videos shared on Twitter show shocking scenes from Brooklyn to Staten Island.
Along the city's busy streets and highways one bus driver navigated floodwaters in and outside his vehicle to get passengers to safety. In other areas, water was recorded pouring down the stairway of one apartment building, and into an underground subway station.
At least one man was seen making the most of the weather. A TikTok video shows an unbothered man floating on a raft smoking a hookah.
New Jersey transit halted due to floods
In neighboring New Jersey, PowerOutage.us reported more than 73,000 power outages early Thursday.
Newark Airport was temporarily evacuated Wednesday evening after flood water got into the Terminal B baggage claim and ground-level floors of the airport. All flights in and out of the airport were cancelled for a time.
New Jersey Transit also suspended rail service, except for the Atlantic City Line, Wednesday.
In Passaic, New Jersey, the city's Mayor Hector Lora reported at least one man in his 70s died after the car he was riding in was overtaken by water.
Rain was not New Jersey's only concern Wednesday.
The National Weather Service confirmed at least one tornado seriously damaged homes in Mullica Hill, in southern New Jersey near Philadelphia. One video shared online showed at least one home completely destroyed.
"Just spoke with Harrison Township Mayor Lou Manzo about the devastating tornado that ripped through the Mullica Hill community and surrounding area tonight," New Jersey Gov. Phil Murphy tweeted. "We're closely monitoring the situation and will do whatever is needed to support the response & recovery in the days ahead."
Flooding was also a serious issue.
Residents in parts of Trenton, New Jersey were urged to evacuate after city officials said the Delaware River posed a serious flooding risk--the first of its kind in 10 years. The effected areas impacted at least 500 homes.
Captain Jason Astbury of the Trenton Police Department told those residents they should at least be prepared to be gone for potentially two days until floodwaters are cleared.
Tornadoes also hit Maryland and Pennsylvania
Multiple tornados also touched down in Maryland and Pennsylvania.
Local news channel, ABC6, reported that one woman died in southeastern Pennsylvania after a tree came down onto a home.
"We were struck very hard with significant damage to the township building, to the high school, multiple homes, buildings at Temple's Ambler campus, and right now we really don't know exactly how bad the damage is," Upper Dublin Township Manager Paul Leonard told ABC6.
Pennsylvania recorded more than 71,000 power outages early Thursday morning.
Earlier on Wednesday, a tornado touched down in Anne Arundel County, Maryland, causing serious damage to homes and businesses. The National Weather Service confirmed that a tornado touched down in Annapolis at 2:15 p.m. Heavy rains also caused isolated flooding in the towns of Rockville and Frederick.
The floods are being blamed on the death of a 19-year-old man in Rockville early Wednesday morning. Melkin Daniel Cedillo drowned in the flooding at Rock Creek Woods Apartments, according to Montgomery County Police. Residents of that apartment building were forced to evacuate because of flooding.
As the sun rises on Thursday many residents in the Northeast are still in danger.
All of eastern Pennsylvania and New Jersey and Delaware are under a flash flood watch, until 2 p.m. Thursday. Local officials said they will continue to monitor flooding of the Delaware River around parts of New Jersey and Pennsylvania.
