The weather this year has been a big issue in the southern alps. Far more storms than usual, and a mix of weather patterns – all involving instability – which makes the routes very risky through high passes.
The normal pattern is for 4-5 days of stability, building to a storm, clearing and returning to stability.
This year it’s been a b*gger in the Valais region; 1-2-3 days of clear, but with storms building quickly and then settling in as storms for 4-5 days (!) leaving only narrow windows of clear each day.
As a solo walker, it is too risky to trek some days on my own with such varied conditions. The storms have been impressive and have kept me in one place for 2-3 days at a time before finding a clear window – essentially scuppering many of my planned routes.
It’s been a constant frustration and the worse year for trekking that I have seen…. :-(
