Sierra Nevada 2022/23
Armed with a new snow-reproduction system, they are confident that with a little help from the weather, they will have sufficient snow coverage for skiers to enjoy the slopes in time for the December bank holiday of the 6th and 8th of the month.
Said publicly owned company, Cetursa, said that with its new water pumps and air compressors at the heart of the snow cannon network, together with the cold snap forecast from Monday, they will be on schedule for opening the 2023-24 skiing season.
This weekend will be uncommonly (for this time of year) warm but there is a Polar front moving in, which will sweep down from the North of Spain… hopefully.
Readers might remember that on the 20th of October, right at the very top of Sierra Nevada there was the long awaited (though short lived) snow cap, that was left in the wake of Storm Aline. There was 10 cm of snow in the Borreguiles area and around 20 cm on the Veleta Peak.
