Philip Hoyle spent Thursday evening in a sleeping bag in the encampment’s library, wearing every article of clothing he owns.

“It was at that threshold,” Hoyle said of the cold. “Any more colder, and I was gonna be feeling it.”

Protesters haven’t faced a serious cold snap since late last month, but have spent time expanding the camp’s “comfort tent” to provide blankets and cold-weather clothing and accessories. A volunteer at the medical tent said Thursday evening’s windy cold hadn’t resulted in protesters needing more medical attention — it was business as usual Friday, where a few protesters milled about in the morning sunlight.

The forecast for the weekend is chilly with a “solid chance at again attempting the freezing mark,” writes A. Camden Walker of Capital Weather Gang. As the weather grows colder, D.C. officials are voicing concern.

“I think we should continue to monitor the situation, and once circumstances become such that health, sanitation or safety become an issue, we are going to have to ask them to leave as overnight guests,” Mary M. Cheh (D-Ward 3) said Tuesday.

U.S. Park Police spokesman Sgt. David Schlosser said earlier this week that the agency has no immediate plans to remove protesters from the park.
