There is great concern, especially in Northern Italy, for the wave of bad weather that will hit the northern regions between tomorrow evening and on Friday night. The alarm had spread that the tail of Hurricane Erin would unleash him, but the new forecasts speak of a different scenario.
Erin was born in the Caribbean in mid -August as a powerful category 5 hurricane, with destructive winds and an initially worrying trajectory. However, approaching the coldest waters of the northern Atlantic, it has lost its tropical nature by transforming itself into a deep Atlantic depression. It is therefore no longer a hurricane, but of an extra -ropical storm, a very different phenomenon and more similar to the perturbations that characterize European autumns.
Direct effects on Western Europe
The low pressure center, with exceptionally low values for the season (about 952 HPA), will remain on the north-eastern Atlantic. Here it will cause twenty stormy and high waves, particularly affecting the United Kingdom and the coasts of Western Europe. For Italy, however, the direct arrival of the former Erin is not foreseen, but only the passage of the disturbed front front, which will slide on central Europe, also bringing instability on our country.
Because there is no talk of hurricane in Italy
It is important to distinguish between hurricane and extra -ropal depression: the first has a warm heart and a symmetrical structure, while the second is fueled by thermal contrasts and associated with fronts. Talking about “Hurricane Erin on Italy” is therefore inaccurate and risks feeding unnecessary alarmism. What will come to us is an Atlantic disturbance, active but completely different from a tropical cyclone.
Bad weather in the north, heat in the South
So what should we expect for the next few days? The most critical situation, as mentioned, will be above all in the North, with locally intense thunderstorms and risk of storms and hailstorms and strong winds. The first rains will arrive since Wednesday 27 August, in particular on the central-western Alps. Between Thursday and Friday there will be a more marked worsening: the northern regions and part of the Tyrrhenian side of the center will live days of strong showers, accompanied by gusts of wind and violent phenomena.
However, Italy will be literally split in two: on the one hand rains and instability, on the other sun and intense heat. Unlike the North, in fact, Center and South will remain under the influence of a warm call: the temperatures will rise above 35 degrees on Sardinia, Puglia, Sicily and Calabria, with a sultry and oppressive climate.
