A blizzard has battered the Mid-Atlantic region of the United States, quickly dumping large amounts of snow that piled up on roads and toppling trees on to buildings and cars.
Officials urged people to huddle at home for the weekend, out of the way of crews trying to keep up with a storm that forecasters said could be the biggest for Washington, DC, in modern history.
A father and son were killed in Virginia when a tractor-trailer struck and killed them after they stopped to help another driver.
A record 30 inches or more was predicted for Washington. As of early Saturday parts of Maryland had seen up to 20 inches of snow and more than eight inches had fallen in DC. Forecasters expected snowfall rates to only increase, up to two inches per hour until daybreak.
Blizzard warnings were issued for the District of Columbia, parts of New Jersey and Delaware and some areas west of the Chesapeake Bay.
"Things are fairly manageable, but trees are starting to come down," said DC fire department spokesman Pete Piringer, whose agency responded to some of the falling trees. No injuries were reported.
Airlines cancelled flights, churches called off weekend services and people wondered if they would be stuck at home for several days in a region ill-equipped to deal with so much snow.
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.
Shoppers jammed aisles and emptied stores of milk, bread, shovels, driveway salt and other supplies. Many scrambling for food and supplies were too late.
