A video of a Carmelite sister brandishing a chainsaw and mowing down hurricane-fallen trees has gone viral since it was posted to the Miami-Dade police department’s Facebook page yesterday.

Here’s the video, in case you haven’t seen it yet:

“Thank you Sister and all of our neighbors that are working together to get through this!” the police said in their post, which also included a couple photos of the sister.

The nun, Sister Margaret Ann, was spotted chopping up fallen trees by an off-duty officer, who took the videos.

Sr. Margaret Ann is the principal of Archbishop Coleman F. Carroll High School in Miami, which praised the nun on their Facebook page:

“Our very own Principal, Sister Margaret Ann, was recognized on CNN and several other news stations for helping out our school community after Hurricane Irma. We are so blessed to have her and the Carmelite Sisters at our school. We are proud of the example they show for our students and other members of the community every day,” the post read.

Sr. Margaret Ann told CNN that she saw the trees blocking the road.

“The road was blocked, we couldn’t get through, and I saw somebody spin in the mud and almost go into a wall, going off the road. So, there was a need, I had the means — so I wanted to help out,” she said.

She knew she could find some chainsaws in the school closet, so she grabbed one and got to work.

“We teach our students, do what you can to help. And this was an opportunity where I could do something to help, and thanks be to God I was able to do it,” she said.

She added that some alumni from the school saw her at work, recognized the habit of the sisters from the school, and stopped by to help her out.

Sr. Margaret Ann is a member of the Carmelite Sisters of the Most Sacred Heart of Los Angeles, who posted the videos of Sr. Margaret on their Facebook page, adding: “We are praying for all those affected by Hurricane #Irma and for all those helping in the recovery effort!”
