Dozens of New York City public schools reported flooding Friday – forcing kids to shelter in place or move to higher floors – as torrential rain pummeled the Big Apple, officials said.

“We have reports of flooding in a number of schools but no children are in danger as far as we know,” Gov. Kathy Hochul told NBC in a Friday morning interview.

“Children are either being sheltered in place, moved to higher floors or, in some cases, parents have been asked to pick up their children.”

By noon, roughly 150 of the city’s 1,400 schools had experienced some form of flooding, Schools Chancellor David Bank said during a weather briefing.

Students at one Brooklyn elementary, PS 312, had to be evacuated to a nearby school because its boiler was smoking — possibly because water got in, Bank said.

“We have taken on some water, but nothing that has created an infrastructure problem where our kids are not safe. Our kids are safe and we will continue to monitor the situation,” the chancellor said.

Reports on social media earlier Friday indicated the basement and lower levels of some schools buildings in the hard-hit boroughs of Brooklyn and Queens were being inundated with flood waters.

There were also reports of overflowing toilets and flooded cafeterias at some schools.  

One father posted an “urgent” message he’d received from his child’s school, which wasn’t identified, that urged parents to pick their kids up immediately due to flooding.

“Urgent! The school is flooded in many places, including the cafeteria. There is no way to serve lunch, water is backing up from drains, and the building is not safe for children. We need all families to come pick up their children as soon as possible,” the tweet read.

Banks said they’d been made aware of a “premature” message fired off by the principal of Brooklyn’s IS 228 asking for parents to pick up their children.

But the DOE boss ripped the principal, saying the alert was “precisely the wrong thing to do.”

“The conditions are worse outside of the schools,” Banks said.

Gov. Hochul, who earlier declared a state of emergency over the “dangerous, life-threatening” storm, insisted that parents would be “contacted by their schools there’s a change in circumstances.”

“Parents are worried about their children in schools they dropped them off a few hours ago when the conditions were not as they are unfolding right now,” she said.

Mayor Eric Adams, who came under fire for his slow response to the flooding, warned New Yorkers to hunker down at about midday – hours after hundreds of thousands of kids had already braved the weather to head to class.

Hizzoner defended his administration’s decision not to shut schools despite the flash flooding, arguing it would have been “disruptive” for any parent who can’t work remotely.

“What … does the store clerk, the police officer, firefighter, the EMS operator do? It is so disruptive when you state that all of a sudden you have to figure out childcare for your child,” Adams said as he gave an afternoon storm update.

“This is gonna take us a little longer to get home and a little longer to get to school,” he continued, adding that it was a “safe environment” once students were inside.

“Kudos to the chancellor for making the right call,” Adams added.

In preparation for dismissal, city officials said schools buses were already pre-positioned to take children home from school.

“We’ve been in touch with all of our vendors. And their preposition means that they are staging early in order to have enough time to get our kids home. These are high … vehicles and they will be able to navigate any water in the roadways,” the chancellor said.

In an interview with CNN Friday afternoon, Gov. Hochul added getting kids home safely was a priority – especially given the subway system had been “so disruptive.”

“In New York City a lot of children, especially teenagers, take the subway to get to school. So we’ve been working on getting the buses working with the City of New York to make sure they get home safely.”

Wild scenes of flash flooding had unfolded across the city through Friday as potent rains tore through the tri-state area — swamping subways and basements and flooding streets and highways.

Up to 5 inches of rain fell in some areas overnight Thursday and as much as 7 inches more was predicted throughout Friday, the National Weather Service said.

“Count on this for the next 20 hours,” Hochul warned in an interview with NY1.

“We anticipate, we warn, we prepare. But then when it hits and you have 5 inches in the last 12 hours — 3 in the last hour this morning — that’s a scale that we’re not accustomed to dealing with.”
