19 August 2019

From a meteorological point of view, after a long period of pleasant summer weather, from yesterday evening a vast perturbed front reached the Valle d'Aosta. For today great variability is expected with alternating dry and showers or thunderstorms, while tomorrow precipitation will be more intense and frequent. This situation will be associated with a drop in temperatures that will record an isotherm of 0 degrees around 3,600 / 3,800 meters today, 3,400 / 3,600 meters tomorrow. The next evolution is uncertain, with a possible partial anticyclonic recovery only from mid-week.

Medium mountain: the rains arriving especially the next night and tomorrow, even if not foreseen as particularly intense, could sometimes cause phenomena of increase in the flow of streams and watercourses that could present problems in their crossing. Recall that, especially in the mountains, it may happen that the center of greatest intensity of rainfall causes waves of floods that quickly reach slopes even far from the heart of the storm. It is therefore recommended to pay particular attention along the paths, especially where watercourses and streams are crossed (the latter, even if normally dry, with thunderstorms could give rise to even major runoff phenomena).
