1. Any storm that delivers more than 3in of snow is a big deal
For any given storm, the District’s Department of Public Works has 750 support personnel and 345 pieces of equipment to help dig us out. That doesn't stop everything from grinding to a halt as soon as a bit of accumulation takes hold.
2. If it snows or sleets, stop doing your homework
DC-area schools are notorious for cancellations and delays at the mere mention of snow, ice, or freezing-rain. Just remember kids, at a certain point, those snow days translate into June-make-up days.
3. And don’t even think about driving. Really. Don't!
You want to observe that inevitable 19-car Beltway pileup on the news from the comfort of your couch, not from the middle of said pileup.
