Next week, violent wave of rain with flood risk; updates » ILMETEO.it

Weather forecast for next weekWeather alert: a heavy wave of rain will hit Italy during the next week. What emerges from the latest updates is a rather dangerous scenario, with serious flood risk for some of our regions due to the arrival of a cold front descending from Northern Europe.

It shouldn’t be too surprising: from the point of view of statistics and climatic weather, the last weeks of the month of November I am among richest in precipitation of the whole year and the reason must be sought at high latitudes where vast depression areas (the classic perturbations) form which often impact first on Western Europe and then also on our country. If anything, what is anomalous is the almost total lack of rain in this first part of Autumn, especially in the North.

Our attention is particularly focused on the second part of the day Monday 21st November when the entrance from the Rhone Gate (southern France) of cold and unstable currents descending from the North Pole, could result in the formation of a dangerous cyclone with direct consequences for our country. As it approaches our peninsula, in fact, this vast depression area will attract mild winds from the south which, crossing the entire Mediterranean basin, will be charged with humidity, consequently supplying the fuel necessary for the genesis of massive storm cells.

The map that we offer below shows the rains expected throughout the day Tuesday 22 Novemberit is eloquent: if this were confirmed it is legitimate to expect showers and thunderstorms in particular in the Northeast and on the Tyrrhenian regions (maximum attention to lower Lazio, Campania and Calabria), with accumulated rainfall locally up to 100mm (yellow color). Heavy rainfall expected for Tuesday 22 November
This could represent a potential risk from a hydro-geological point of view with the possibility of floods and landslides: the greatest danger with these configurations is determined by the fact that storm systems of this type could persist even for several hours on the same areasdischarging to the ground all the water that hasn’t descended during the rest of the year.
It will then return to the Alps snowplentiful and progressively lower oddswith flakes that could go as far as 6/700 meters above sea level (locally even lower in South Tyrol), thus whitening many tourist resorts such as Bormio (SO), Madonna di Campiglio (TN), Solda (BZ) and Cortina d’Ampezzo (BL).

The weather conditions will remain rather unstable also in the following days, especially in the Centre-South, before an expected improvement towards the end of the week. It should be emphasized that the passage of the cold front will leave a dowry drastic drop in temperatures which will make our teeth chatter, especially in the early morning.
