With the expected arrival of actual accumulating snow in D.C. tonight, the snowball fight enthusiasts behind the Washington D.C. Snowball Fight Association are organizing the "Official" Dupont Circle Snowball Fight tonight at 8 p.m.

If you brave the fight or have other snow adventures tonight, we'd love to see your photos. You can send them by tweet, by email, via our submission tool or by tagging your pictures on Flickr with tbddc.

Keep an eye on the event page to check for any changes. Dress warm, snowballers - and don't hurt anybody with iceballs. You know who you are.
