US snowstorm set to continue and affect more states
A storm that has dumped up to 12 inches (30cm) of snow on parts the US Midwest and forced cancellation of 1,100 flights is making its way to states on the Atlantic coast.
The storm, which began in Montana before moving east, follows a series of heavy winter snowstorms that have dropped heavy snowfalls in the Midwest.
