Due to the saturation of the waterways, the bulletin continues, “possible rock falls and superficial landslides, causing temporary interruptions to traffic and localized damage to infrastructure”. For tomorrow, Saturday, “residual instability phenomena are expected due to soil saturation and lower levels but still close to the warning thresholds”.
Regarding the meteorological situation, the bulletin highlights that “a minimum brings precipitation in the form of showers for today: the most intense part, linked to the front, ends in the morning/central hours, but a ‘tail’ of instability passes this afternoon, with generally weak showers, but with considerable uncertainty locally moderate or strong and localized phenomena cannot be excluded”.
From 3pm to 6pm today, Friday 21 June, according to the Civil Protection, “between 5-8 mm on average and 15-20 mm maximum fell in all areas; a little more intense in the south-eastern and north-western sectors. The levels are still above the warning thresholds, slightly decreasing in some sections“. “Residual storms are still expected until late in the evening and the phenomena will end during the night”. In the late afternoon, a “local flooding of the Dora in Bard was recorded, at km 55 on state road 26” and, otherwise, “there are no further critical situations caused by bad weather compared to those” that have already emerged.
