Postal delivery was suspended Saturday for Northern Virginia, Washington, D.C., Southern Maryland, and Suburban Maryland, MyFoxDC.com reported.
Several thousand people in West Virginia, Virginia and Pennsylvania had lost electricity and more outages were expected as the snow began to bring down power lines. Authorities blamed the storm for hundreds of accidents. Some area hospitals asked people with four-wheel-drive vehicles to volunteer to pick up doctors and nurses to take them to work.
The snow comes less than two months after a Dec. 19 storm dumped more than 16 inches on Washington. Snowfalls of this magnitude -- let alone two in one season -- are rare in the area.
