An Atlantic weather system will bring rain and wind to Sardinia between Thursday 12 and Friday 13 November, with weather events more likely on the western side. Forecasts also point to rising seas and possible rough seas along exposed coastlines; conditions will remain unsettled over the weekend.
According to iLMeteo.it meteorologist Lorenzo Tedici, winds could strengthen, with gusts reaching 60–80 kilometres per hour. This estimate concerns the weather system as it crosses the Island: significant wave heights of 3 to 4.5 metres are expected, with peaks of 5 metres offshore and a high risk of rough seas along the western coast.
The ARPAS bulletin for Friday and Saturday forecasts cloudy skies and isolated or scattered precipitation, including showers or thunderstorms. These weather events may be more frequent in western areas, with accumulations generally light and locally moderate. The agency forecasts falling temperatures, light or locally moderate westerly winds, and very rough seas.
The wind and wave figures are therefore separate estimates from the regional outlook issued by ARPAS. The national monitoring bulletin of 10 November also forecast isolated or scattered, generally light precipitation in western Sardinia, and very rough seas tending to become high. For persistent and heavier rain, the national forecast pointed mainly to eastern Liguria and northern Tuscany.
Wednesday 11 November is expected to bring high cloud, becoming thicker from the afternoon, and possible mist or fog in the Campidano during the early hours; temperatures will remain broadly stable. From Thursday, instability will increase and temperatures will fall as the bad weather sets in, with minimum temperatures forecast to rise on Thursday according to the outlook published the previous day.
The weather system will also affect other parts of Italy. The system, arriving from the Atlantic, will first reach Liguria and northern Tuscany; from Friday it will also affect Friuli, Lazio and Campania. The Adriatic side will be relatively more sheltered, while strong winds and rough seas are expected along the Tyrrhenian coast.
According to iLMeteo.it forecasts, on Saturday 14 November the bad weather will move towards the southern regions, with the last weather events mainly over the southern Tyrrhenian Sea and in Apulia. More stable conditions are expected on Sunday 15, as high pressure expands. For updates on the weather system on the way in Sardinia, forecasts therefore point to a more unsettled spell between the end of the week and Saturday, especially along the western coast.
