Success! You're on the list.

There’s a good chance you blocked last year’s relentless winter from your memory, which is an understandable instinct to help guide you now.

But it’s cold again and D.C. will activate its Hypothermia Alert tonight at 7 p.m. and it’s important to remember what to do if you come across anyone in need of shelter tonight: Call the Shelter Hotline at 1-800-535-7252 or 311.

Save those numbers. This, unfortunately, won’t be the last time you’ll need them this season.
