Atlantic disturbance is coming, heavy rains and thunderstorms from tomorrow

The new week will mark a clear change of pace compared to the previous days, offering a decidedly more dynamic and fully autumnal scenario, particularly in the first half. The advancement of the western currents will favor the arrival of a well-organized disturbance directed towards the Mediterranean basin. Federico Brescia, meteorologist at iLMeteo.it, explains that today, Monday 19 October, conditions of marked instability will be confirmed in the North-West, with locally intense phenomena which will primarily affect Western Liguria. Between Tuesday 20th and Wednesday 21st October, the entry of the very extensive Atlantic perturbed system will lead to a phase of widespread precipitation across a large part of the country.

The regions of the North-West, and in particular Liguria and Piedmont, will be exposed to continuous and abundant rainfall. By Wednesday afternoon, overall accumulations could exceed 100-150 mm in the Savonese area. With the progressive advancement of the front, by Wednesday afternoon the rainfall will extend to almost the entire national territory.

Particular attention should be paid to the Tyrrhenian sectors, Tuscany and Lazio first and foremost, which are traditionally more exposed to this type of Atlantic configurations. From Wednesday the winds will move from the western and south-western quadrants: the intense Libeccio currents which will blow at over 40 km/h could generate storm surges along the exposed coasts of Liguria and Tuscany with waves up to 3-4 meters high. From Thursday, following the transit of the disturbance, there will be a drop in minimum temperatures of around 2-4°C.
