A new storm system will bring rain, strong winds and rough seas to Sardinia during the week, with the most unsettled period expected between Thursday 12 and Friday 13 November. Forecasts from iLMeteo.it and the ARPAS bulletin indicate heavier weather, especially in the island’s western areas, and possible storm surges along exposed coasts.
The first rainfall is expected as early as Tuesday 10 November, particularly in the west, with estimated accumulations of between 10 and 25 millimetres over 24 hours. Minimum temperatures are expected to rise, while maximum temperatures should remain mostly stable. The national critical-weather bulletin for Tuesday did not indicate an alert for Sardinia: the wind and rough-sea forecasts for the following days describe a weather scenario, not an alert for those dates.
On Wednesday 11 November, widespread cloud cover is expected, with high cloud that could become thicker in the afternoon. Fog or mist is possible in the early hours along the Campidano. Temperatures should remain steady; winds, light or locally moderate, will initially come from the west before shifting south.
Conditions will deteriorate more markedly from Thursday, when skies will be cloudy or very cloudy, with isolated or scattered rainfall possible, including showers and thunderstorms. The weather may be more intense in western areas. Seas are forecast to be rough or very rough on Thursday, while on Friday the western waters could become very rough.
According to the forecast from iLMeteo.it, reported by meteorologist Lorenzo Tedici, southerly winds will strengthen between Thursday and Friday. Gusts could reach 60–80 kilometres per hour, with peaks of 90 on mountain ridges and along exposed Tyrrhenian coasts. Significant wave heights of between 3 and 4.5 metres are forecast, with waves reaching up to 5 metres offshore and a high risk of storm surges along western coasts. Southerly currents will keep conditions mild, with maximum temperatures expected to range from 22 to 27 degrees.
Temperatures are expected to fall overall during the unsettled period, although minimum temperatures could rise on Thursday. For comparison with the recent bad weather, Sardinia had been affected by a previous spell of bad weather between 4 and 5 November, separate from the storm system forecast for this week.
The storm system will move on towards the southern regions on Saturday 14 November, with the last showers expected mainly between the southern Tyrrhenian Sea and Puglia. For Sunday 15 November, iLMeteo.it forecasts high pressure spreading in, bringing more stable and dry conditions across much of the country.
