A huge mob of rowdy winter warriors descended on a Manhattan park on Monday afternoon — throwing snowballs in a chaotic scene and tormenting cops, according to authorities and witnesses.

Around 4:13 p.m., police responded to a 911 call about a disorderly group of people inside Washington Square Park, according to the NYPD. 

Arriving officers found a large group of revelers throwing snowballs and observed pure pandemonium as hundreds of people launched frozen projectiles at each other and oncoming traffic, according to police and witnessed by The Post.

“The New York City blizzard snowball fight has happened. It was complete pandemonium,” said a man who showed up for the fight.

“This s–t ain’t safe. I got hit in the ear, and it’s been ringing for 20 minutes,” he said.

At one point, people in the large group were seen tossing snowballs at an NYPD vehicle as officers got inside and drove off on a street beside the Greenwich Village park.

Members of the crew were also spotted lobbing the occasional snowball at officers — with at least one cop holding up a can of pepper spray and warning the crowd to back up. 

Cops were heard over a megaphone telling revelers to “enjoy themselves,” but not hurl any snowballs at cars.

No injuries were reported during the blizzard mayhem, cops said.

The Police Benevolent Association, the city’s largest union repping NYPD cops, blasted the snowball fight as a “despicable attack” on cops.

“Unacceptable and outrageous — this is the environment that NYC police officers are up against,” the PBA said in a statement.

“The individuals involved must be identified, arrested and charged with assault on a police officer. And all of our city leaders must speak up to condemn this despicable attack.”

Detectives’ Endowment Association President Scott Munro also called out the troublemakers.

“What we saw in Washington Square Park today was not harmless fun — it was a deliberate, outrageous, and dangerous attack on uniformed police officers,” Munro said.

“Make no mistake: detectives will do what they always do. They will identify those involved and they will apprehend them.”
