Still-open ski centres in the western US have seen record snow accumulations for May in the last few days.
The Palisades reported over two-feet (60cm) of snowfall in 24 hours on Saturday/Sunday and the high Sierra Nevada region in California posted its heaviest May snowfalls on record.
The snowfall has now moved east into the Rockies region where accumulations of over a metre (3.5 feet) are forecast by Wednesday morning. Snowbird in Utah posted 16 inches (40cm) in the first 24 hours of the storm. The snowfall has also taken it through a 600" (over 15 metres) seasonal snowfall to date mark.
The snowfall is arriving with gale force winds at times bringing blizzard conditions, US government agencies have issued winter storm warning and some roads have been temporarily closed.
There are currently still nearly 20 ski areas open in the USA, more than any other country, located in Arizona, California, Colorado, Oregon and Utah as well as in Vermont on the East Coast.
