A roof collapsed at a New Jersey wholesale club on Monday morning with more than 20 people inside, according to authorities.

​Emergency personnel raced to BJ’s Wholesale Club in Ocean Township yesterday at around 11.16 a.m. The incident followed heavy flooding and storms across New Jersey.​

Twenty-seven people were inside the building when the roof caved in, with two becoming partially entrapped, the Monmouth County Sheriff’s Office said in a statement.

The two individuals were able to free themselves and managed to escape the building. ​No injuries have been reported, the sheriff’s office said. ​

Dramatic footage of the incident obtained by CBS News showed the ceiling collapsing as shoppers fled from a surge of water that followed.

Several of the store’s stands were knocked over by the torrent, with one shopper being shoved by a trolley and a table covered with products.​

Searches of the building were conducted using the Monmouth County Sheriff’s Office interior drone and New Jersey Urban Search and Rescue K-9 teams.​

A coordinated response involving Ocean Township Police, Fire Districts 1 & 2 and OEM, as well as the sheriff’s office, MedStar and the Monmouth County Urban Search and Rescue Team, was also rolled out. The latter agency conducted its own “comprehensive” search of the building. ​

“This incident is another reminder of how quickly severe weather can create dangerous and unpredictable conditions,” Monmouth County Sheriff Shaun Golden said, while commending the emergency workers who responded to the incident. ​

Golden added, “Despite the ongoing flooding and severe weather affecting our communities, all worked seamlessly together to ensure everyone was safely accounted for. Their dedication and teamwork exemplify the very best of public safety.”​

Images of the flooding shared by the sheriff’s office showed vehicles partially submerged in water. ​

Motorist Duval Moore told CBS News that the flood has caused chaos on the roads. ​

“It just got bad. Like, all of a sudden, within minutes, it was low, then it just got high,” he said.​

Governor Mikie Sherrill confirmed on social media on Monday that the New Jersey Office of Emergency Management remains activated and acknowledged that communities had been “hit hard” by the days-long deluge.

In an update, the Monmouth County Sheriff’s Office warned residents and visitors to use caution as “floodwaters may remain in some areas.”

​“Never drive through flooded roadways, and follow the guidance of your emergency officials,” the sheriff’s office noted.​
