She’s not messing around.

“Will & Grace” actress Debra Messing blasted the horrific gridlock outside a hospital in New York City as snow remains piled up on the streets a full week after Winter Storm Fern passed — and said that Mayor Zohran Mamdani is to blame.

Messing, 57, bemoaned a trip to an appointment that dragged on for more than an hour early Saturday after her taxi encountered bumper-to-bumper traffic while an ambulance tried to squeeze through.

“The streets are a disaster. It hasn’t snowed in 5 days and the streets still haven’t been cleared. Poor ambulance sitting in [essentially] a parking lot with sirens going. I’m praying for the person needing emergency care,” she wrote in a post on X.

“I’ve lived here for 15 years (this go around) and this has never happened. The plows have always worked around the clock to get the city back to working. I wonder what happened? Hang in there New Yorkers,” the Brooklyn-born, NYU-educated star wrote.

Though Messing didn’t call out Mamdani by name, many linked her sarcastic sign-off to her past critiques of the self-declared socialist.

Messing, who voted for Andrew Cuomo in the mayoral election, crashed out on social media in November and posted a series of memes labeling Mamdani an “American-hating jihadist” and crudely nicknaming him “Osama bin Mamdani.”

Since then, she’s largely avoided mentioning Mamdani online. But the snowstorm tested her resolve — and many agreed with her sly jab at Hizzoner over the state of the streets.

“I guess the warmth of collectivism isn’t warm enough to melt snow,” one user quipped.

“The collective is waking up,” another added.

“Ah man, the warmth of collectivism not only isn’t melting the snow, it’s not getting the snow plowed, either. You love to see it…,” one joked.

Those quips are all references to Mamdani’s socialist vow to “replace the frigidity of rugged individualism with the warmth of collectivism.”

When Winter Storm Fern blanketed the city in snow on Jan. 25, Mamdani assured that city employees would be working “around the clock” to keep “the city moving.”

Over the last week, trash has piled up on the sidewalks on the Upper East Side — though notably not around Gracie Mansion — and heaps of snow remain at every crosswalk.

Mamdani even tried to put his back into shoveling, and still managed to disappoint.

He ordered virtual learning for NYC schools on Jan. 26, but that too was a certified disaster as students and parents alike struggled just to sign on.

At least 14 New Yorkers died in the deep freeze, but Mamdani still insists that he “struggles” to imagine how his job “could be better” so fresh out of the gate.
