Icey and wet roads and pavements were blamed for many of the deaths with one occurring during a 15-car accident in the eastern state of New Jersey that also injured 28 people.

Winter storm warnings were also in effect in Vermont, New Hampshire, and northern and western New York.

Transport officials in the state of Oregon warned drivers not to attempt to use coastal roads as the second of two storms blew through.

Wind gusts of more than 160 kph were reported along the Oregon coast, with the highest reading at 207 kph at Bay City, the Weather Service said.
 
Helicopter rescues were being launched for stranded hikers and residents trapped by flooding, state emergency management officials said.
 
In southwestern Washington state, one man died when a tree fell on him as he was trying to clear one that had been toppled, a local police chief said.
