Residents in the western U.S. state of Colorado are struggling to cope with their third huge snowstorm in as many weeks.

Forecasters say as much as 20 centimeters of snow is expected to fall on the city of Denver Saturday, while the state's rural southeastern region could get five centimeters of snow on top of what already covers the ground.

The new storm is carrying winds up to 50 kilometers an hour, hampering efforts by the National Guard to airdrop hay bales to feed cattle stranded on snow-packed pastures. The animals could die of starvation or dehydration if not fed.

The state has still not recovered from two consecutive snowstorms last month. The first one stranded thousands of passengers traveling in and out of Denver's airport just days before the Christmas holiday.
