Lucrezia Ciotti The Center-North Italy is experiencing a phase of marked atmospheric instability, with widespread rainfall and intense thunderstorms linked to the passage of a particularly active Atlantic disturbance. The conditions weather They are aggravated by the clash between air masses of different origins and by a high supply of humidity, which is fueling persistent and locally intense phenomena.
Here are the updates on theAlert and the affected regions.
Intense disturbance and clash between air masses: persistent bad weather in central and northern Italy
The phase of strong instability continues meteorological which is currently affecting the central and northern parts of the peninsula. The Civil Protection Department has issued a new warning bulletin for adverse conditions, linked to a large Atlantic depression fed by two particularly active frontal systems.
This configuration is causing very heavy and, above all, long-lasting rainfall, which is affecting the same areas already affected in previous days.
The atmospheric picture is made even more energetic by an intense contribution of humidity Coming from the Mediterranean Sea and, upstream, from North Africa. The warmer-than-seasonal Mediterranean waters, up to 2-3°C above typical temperatures, also reinforce the system, accentuating the thermal contrast and increasing the likelihood of downpours and intense thunderstorms.
Added to this scenario is the presence of southerly winds such as Libeccio and Sirocco, with gusts that can reach and exceed 70-80 km/h, helping to transport further humidity and provide energy to storm systems. The areas most affected they result in the Central-Northern Italy and Sardinia, with widespread and locally very heavy rains. Particularly exposed Eastern Liguria and Upper Tuscany, where in a few hours the amount of rain comparable to that of two months could fall. Also involved Lombardy, Emilia-Romagna, Veneto, and Friuli-Venezia Giulia.
Weather alert in Italy, heavy rains and thunderstorms on the way: the affected regions
In Tuscany the operations room of the regional Civil Protection has ordered an orange alert due to hydrogeological risk in the areas already affected by recent fires on Mount Faeta, where the terrain is more fragile and subject to potential landslides. On the same day, firefighters also activated a yellow alert for strong thunderstorms across much of central-northern Tuscany, valid from 7 a.m. until midnight. The following are expected: rainfall scattered, including showers or thunderstorms, with accumulations that can locally reach 100-120 mm or exceed these values in the northern areas.
A widespread network also remains active yellow alert in several areas of the countryIn Emilia-Romagna, the Bologna Plain is affected due to flood risk. In Lazio, the Northern Coastal Basins and the Middle Tiber Basin are affected due to storm risk. In Lombardy, the areas of the Bergamo Orobie, Lario and Western Prealps, the Varese Lakes and Prealps, and the Milan Hydraulic Node are affected, with critical situations both due to storms and hydrogeological risk. In Umbria, the alert affects the Chiani-Paglia and Middle Tiber areas due to thunderstorms.
