I lived in Prince Georges County for 7 1/2 years of my AF career. They don't have the snow clearing capability for the amount of the streets there for large storms. It will take weeks to get most of the burbs open again. The majority of the population knows this and so clean out all the food before a big storm.

Also, they get at least one big storm every winter. High pressure systems will stall just off coast and cause a strong low pressure system to rotate back west after picking up moisture from the ocean and dump and dump and dump until the high pressure system moves out of the way.

Movement comes to a standstill. Ironically enough, the worst storm I went through while there was the only time I ever saw neighbors helping each other out. We got 2 feet in 3 days with that one. Biggest danger is all the trees. The snow snaps limbs and knocks down the power lines.
