Weather tracker: Heavy snow blankets parts of US as winter storms hit

Snowfall moves south-east over Wyoming and Colorado and combines with dense fog in some areas

A cold spell continued to grip parts of the US this week. After a winter storm brought 20-30cm of snow across Wisconsin, and even up to 35cm in places last weekend, the focus of the winter weather hazards shifted elsewhere early this week.

A storm system moving south-east over Wyoming and Colorado brought a continuous period of snowfall until Thursday morning. Central Colorado and northern New Mexico bore the brunt of the snowfall with accumulations reaching 30cm in places. The heavy snowfall across the Denver region was its first of the winter and caused widespread disruption to flights into and out of Denver on Wednesday and Thursday. Almost 1,000 flights were delayed or cancelled as a result of the treacherous conditions.
