DAVOS, Jan 23: The global economy and geopolitical tensions are taking a back seat to a more immediate problem at this year's Davos summit of political and business leaders: heavy snow is burying the venue.

High in the Swiss alps last night, on the eve of the opening sessions, many of the roughly 3,000 delegates struggled to reach the ski resort.

Part of the main train line into Davos was buried in snow over the weekend, forcing people onto buses, and helicopters were disrupted by poor visibility.

Some pre-summit meetings were cancelled or delayed as the first waves of delegates waded through snow-blanketed streets with luggage, looking for their hotels, or had to wait for road crews to dig their limousines out of drifts.

Businessmen slipped over on icy patches as snow ploughs roamed the streets, with the snow returning as fast as the machines could clear it.

World Economic Forum communications chief Adrian Monck said it appeared to be the heaviest snowfall for the four-decades-old summit since 1999-2000, though he described it as more of an inconvenience than a real threat to attendance.

"We know the snow causes inconvenience and it puts a lot of pressure on the city of Davos as a host but so far we have not seen any drop-off in registrations," Mr Monck said.

Taoiseach Leo Varadkar is among those attending the conference this week, while Irish disability activist Sinéad Burke will be at the conference speaking four times on topics of diversity, inclusion, design and education.

With the weather forecast to clear on Tuesday, organizers are hoping transport will start to operate more smoothly and will be running without a hitch by the time US President Donald Trump arrives on Friday to give the closing address.

However, so much snow has built up on the slopes surrounding Davos that avalanches remain a danger.

A bulletin from the SLF Institute for Snow and Avalanche Research in Davos showed a broad band of the mountainous country under Level 5 avalanche danger, the highest on a 1-5 scale.

"Fresh snow and snow drift accumulations are prone to triggering (avalanches). Until late in the night a large number of natural avalanches are to be expected," it said.

Local officials said yesterday they had evacuated two dozen residents from vulnerable areas while crews used explosives to reduce dangerous build-ups on some slopes above the town.
