A lack of early snowfall has forced multiple resorts to push back their opening dates for the 2020-21 ski season in the Rockies and throughout New England.

In Colorado, Winter Park Resort made the decision to delay opening to "allow more time to expand on-mountain terrain openings and limit crowding," pushing back its original opening date of November 18th. While a couple of storms have dropped a fresh dose of powder, the resort is anticipating an opening date "no earlier" than November 30th.

"We can’t wait to welcome you when the time is right," Winter Park Resort tweeted.

Meanwhile, Colorado's Steamboat Resort has re-scheduled its opening date to December 1.

In New England, mild temperatures have sidelined snowmaking efforts throughout the region, including Vermont, where Killington Resort is usually battling to be one of the first resorts in the country to open each season.
