On Sunday night, several crews were involved in multiple water rescue operations and buildings in the historic town of Ellicott City, as tidal waves raged through the streets after torrential thunderstorms, officials from Howard County said.
Maryland Gov. Larry Hogan announced at 18:40. He had declared a state of emergency in Howard County and was planning to drive to Ellicott City to assess the damage.
The Howard County Fire Department warned the people trapped on the city's main street to get to the second floor of the building, waiting for the rescue, saying the damage could compete with the devastating floods there in 2016. No injuries were reported.
"This is an extremely dangerous and potentially catastrophic situation and you have to drive IMMEDIATELY to HIGHER AREA and WATER MOVE from wherever you are," the National Weather Service warned at 1
Howard County Information Officer, Mark Miller said a stream of water raced through the streets. Miller said the flooding was "as big as the 2016 floods."
The city is flooding, "said Miller. "All our first responders respond."
The Howard County Fire Department warned people to stay away and said hundreds of rescuers in Ellicott City were gathering from northern Virginia. Howard County officials said they would open an emergency operations center to manage their response.
Videos taken on the main street of Ellicott City show boiling brown water flowing down the street with trash and garbage. The water poured into doors and windows and twisted traffic lights.
Abigail Conte, 19, was in the Bean Hollow coffee shop in the historic part of town when the rain started this afternoon. She said employees had announced they would close at 3:45 am due to a flood warning.
She left the store and made her way to her car about half a mile away.
"When I went outside" The road became a river, "Conte said.
She came to a crossroads where it was too dangerous to carry on, and finally sought shelter at Cottage Antiques, at around 6.30pm She was trapped on the second floor of the building and dragged into a back room because she feared a telephone pole might collapse in the shop.
She told the owners of the antique shop that the basement of the building was flooded and said she had it seen a garbage bin and other garbage that flows down Main Street, but nothing major.
"It's just flooded," said a woman on A Journey from Junk, "I'm trying to work through my own panic attack."  Before Hogan has declared a state of emergency, he has activated the emergency response of the state, which sends additional rescue personnel from various government agencies to the scene, sa was his spokeswoman Amelia Chasse.
Several neighboring counties – including Carroll, Frederick, and Washington – sent fast water teams, she said.
"The governor sends his thoughts and deepest sympathies to those affected, including residents and businesses in Ellicott City," Chasse said. "It warns people against being safe, do not come out to see the flood, there's still danger out there."
The Capital Weather Gang reported that radar had shown 3 to 6 inches of rain in just fell in the Ellicott City area for two hours and it continues to rain heavily. Just south of Ellicott City, the radar had crashed as much as 7 to 8 inches.
Jeff Halveson, a professor of meteorology at the University of Maryland in Baltimore County and an employee of Capital Weather Gang, said the storm pattern had essentially stalled over Ellicott City, the same phenomenon that occurred two weeks ago in the city of Frederick led to massive flooding.
He said the storm could drop 10 to 12 inches of rain in total before finally ending between 19:30 and 20:30 He said that he thought the flood could ultimately be worse than what happened in 2016 was seen in Ellicott City.
"To say that lightning strikes twice is basically what happens," Halveson said. "It's extraordinary that this happens weeks apart and 30 miles apart."
Ellicott City suffered heavy damage in a tidal wave that killed two people on July 30, 2016. During this flood, houses trembled along the main street as residents drowned Some of them formed human chains to rescue those stranded in their cars as the rising water thundered through the historic city center, and emergency workers climbed rooftops and hacked holes in the shops to rescue those hiding there.  In the flood of 2016, Joe Blevins, the father of three children, was swept away as he and his wife got out of the flooded car, and his body was discovered the next morning by a wanderer on the shores of Patapsco, another tourist's body, Jessica Watsula, was found under Ilchester Bridge.
