A welcome bout of snow at the end of last week has helped expand Australia's alpine snow cover, which has been slow to build up this season.

A lack of strong cold fronts during the last several weeks has limited snow accumulation in the alps.

At the beginning of last week, there was just over 20cm of snow on the ground at Spencers Creek in NSW. This is less than half the long-term average depth for that time of year.

Fortunately, a series of cold fronts delivered some much needed snow to the mountains late last week, between Thursday and Saturday.

On Sunday, satellite images revealed that the spatial coverage of snow in the alps had grown substantially compared to the beginning of the week.

The snow was also looking good from the ground as ski resorts did their best to get the season underway amid the ongoing COVID-19 restrictions.

Australia's natural snow depth typically increases during July and into August amid the coldest weather of the year.
