Weather, expected clouds and local instability. Rain and thunderstorms from Tuesday

In the North the day will be characterized by the presence of widespread clouds especially in the Western sector, with light rain expected between Liguria and Piedmont, while elsewhere there will be clear spells. In the Center, however, the weather will be more stable and largely sunny in all regions with little cloudy skies. Maximum temperatures of up to 25°C expected in Rome. Finally, in the South, today will see many clouds in the sky with local rain expected between Calabria, Sicily and Sardinia, while elsewhere the sun will prevail with pleasant temperatures.

In detail, the cloudy or overcast sky with isolated showers will concern, in the North, above all the Aosta Valley, Piedmont and Liguria. It will be clear or slightly cloudy in other areas of the north, with instability also expected in Tuscany, in the Ionian sectors and in Sardinia. In the afternoon the rain and cloud cover ease, as will happen in the rest of the country, excluding any precipitation in the Cagliari area. In the evening, clouds will increase again in much of the North.

In Tuscany, in detail, the code yellow weather alert already reported in recent hours on the hills of Fiora and Albegna, on the Grosseto coast and on the islands of the Tuscan Archipelago for strong storms, with hydrogeological and hydraulic risk for the smaller grid, has been extended until 10 am today, Monday 19 October. The Unified Operations Room of the regional Civil Protection has therefore extended the criticality assessment, whose deadline was initially scheduled for 9pm yesterday, Sunday 18th, given the persistence of conditions of marked instability in the area concerned. Locally strong thunderstorms associated with strong gusts of wind and local hailstorms are possible until the early hours of today, particularly on the Archipelago.

As mentioned, the weather is expected to get worse as the hours go by and it is precisely Tuesday the 20th that will be paid attention to by the experts. In the North, specifically, a disturbance will bring a significant worsening, with widespread rainfall and intense thunderstorms especially in Liguria. In the Center the day will see increasing clouds with rain and showers especially in Tuscany, while it will be sunnier elsewhere. In the South the day will be characterized by many clouds and showers starting from Sardinia and Sicily, extending to Calabria.

On Wednesday 21 October, experts still report, the passage of the intense Atlantic disturbance will be completed, with the involvement of almost all regions of the country. The most disturbed phase is expected in the first part of the day when rainfall could still be intense and abundant, even in the form of thundershowers and possible cloudbursts.

Also on Wednesday 21st, the bad weather will particularly affect the Tyrrhenian regions, Umbria, but also the sectors north of the Po and those of the extreme North-East where rainfall amounts well above 100 mm are expected: flooding, landslides and mudslides are expected locally. From the evening there will be a tendency towards a general exhaustion of the phenomena, destined to concentrate between eastern Lombardy and the Triveneto. Abundant snow is expected in the Alps, but at high altitudes. Experts report critical issues related to the wind in the Centre-South and the seas which will become very rough, even rough as far as the Ligurian Sea is concerned.
