A young woman was seriously injured after she reportedly went to a Washington Heights roof to urinate and fell two stories onto the roof of an adjacent building. Her friend reportedly told 911 that she was blown off the roof by strong winds.

Police say the incident happened around 2:15 a.m. Wednesday at an apartment building on W. 179th Street near Audubon Avenue. The Daily News reports that Meri Marabyan, 19, and Jesus Plata, 21, had gone to the building to visit a resident there. Police sources told the News the three were drinking rum and beer in the stairwell, and Marabyan's blood also tested positive for cocaine after the accident. It's unclear if any of that was a factor in her accident.

Both women reportedly went to the roof of the five-story building to urinate when Marabyan fell off and landed on the rooftop of the next door building, which is two stories lower. "[Marabyan] was blown off the roof by the wind," Plata told a 911 operator shortly afterwards. The wind speed was around 7 MPH at that time in the city (the wind gust, which is was not recorded at that time and location by Weather Underground, was likely higher).

Marabyan suffered internal injuries, and was taken to Harlem Hospital, where she is listed in critical but stable condition. According to the NY Post, investigators aren't sure whether she was blown off by the wind or if she simply lost her balance and fell.

In a separate incident on Tuesday, 57-year-old Clifford M. Lemay died after falling from the roof of a seven-story office building in Teaneck, NJ. Police have attributed his death to a "horrific accident," with a peak wind gust around 32 MPH in the area around the time of the fall.
