Announced a few days ago, Italy enters the climax of the phase bad weather fully winter-like due to a very strong outbreak of cold Arctic air, which is entering the Mediterranean, creating the basis for a low pressure area capable of significantly compromising the weather conditions for at least three days: heavy rains, heavy snowfall and very strong winds, it is no coincidence that experts have dubbed it “the perfect storm”.
What will happen at sea
“First a lot ventoThen rain, Freddo and also neve in the plain”, explained Lorenzo Tedici, meteorologist at / which confirmed this mix of phenomena that it could cause”inconvenience and damage, especially due to the wind that will blow very violently from the west, building in the open sea giant waves up to 7 meters on the Ligurian Sea”. What will certainly not be underestimated is what will happen especially in the upper Tyrrhenian Sea, the key area of bad weather, with waves that will reach up to four meters in Liguria while in Tuscany they will be 5-6 metres, but with exceptional peaks between Versilia and Livorno. “Unfortunately it will be a historic storm in Libeccio with potential damage on the exposed coasts”.
The “second” storm
The driving force of the bad weather, on Wednesday 20 November, will move further to the center where the northern coasts of Sardinia and the Lazio coasts will be especially affected with waves up to five meters high: on the following night Campania and Tyrrhenian Calabria will also be affected by strong storms. “We will also have one on Thursday second storm of Libeccio with waves up to 4-5 meters on the Ligurian Sea, descending towards the south in the evening. In practice the ‘perfect storm’ will have at least two phases of strong winds from the south-west, west, north-west”, adds Tedici. In short, the wind will affect much of Italy from today and at least until Saturday when it will finally ease.
Where the rains will hit
Disturbance of polar origin will also cause heavy rains: this time the Tyrrhenian areas from Liguria to Calabria will be targeted with lots of rain for the next three days: the expert predicts final accumulations of 100-150 mmin practice even 150 liters of water per square meter. “From Wednesday to Friday it will always rain in the same areas“.
Snowfall all the way down to the plains
One of the most significant aspects of the “perfect storm” will be the neve which today will begin to fall in the Western Alps above a thousand metres, on Wednesday it will also arrive in the Apennines but the worst day seems to be Thursday 21 November when it could snow up to the areas flat of Piedmont and Triveneto. Milan is also at risk but accumulations will only be seen where it will be coldest, i.e. between Valle d’Aosta and Piedmont.
“With the movement of the Arctic air mass towards the south-east we will have local snow phenomena in the plains on Friday morning, again in the Triveneto area and above all in the central-northern Apennines up to hilly altitudes”.
