Snow showers have continued without interruption since last week, and enormous snowbanks have blocked not only roads but also the railway. Trains running to Klosters, where many WEF delegates are staying, circulated with long delays on Monday morning, but in the afternoon, railway connections were completely interrupted.
Those people who managed to dig their cars out from under the snow now have to spend hours in traffic jams.
"As avalanche risk is high, please ski on open slopes only. Streets around Davos are expected to stay accessible," the website of Davos-Klosters resort said.

Watch out for the #Dachlawine in #Davos (snow falling off roofs).

On Monday, the Swiss Institute for Snow and Avalanche Research (SLF) recorded a "very high avalanche danger over widespread areas."
According to the WEF organizers, over 3,000 participants from more than 110 countries are to be in attendance, with more than 70 heads of state to take part in the global forum.
