Yellow alert for thunderstorms in Tuscany, bad weather in the Northwest.

A rapid worsening of weather is expected today, Friday, October 23, 2026, with new rainfall and thunderstorms affecting mainly Northwestern and Central Italy. The Civil Protection has issued a yellow weather alert for thunderstorms and hydrogeological risk in some areas of northern Tuscany, specifically the Serchio-Garfagnana-Lima, Lunigiana, and Versilia zones.

According to the National Meteorological Vigilance Bulletin, isolated to scattered precipitation is expected throughout the day, including showers or thunderstorms, in Valle d'Aosta, Alpine sectors of Piedmont, Liguria, Lombardy, Triveneto, Emilia, and Tuscany. The phenomena will extend in the evening to Umbria and north-central Lazio, with generally weak cumulative amounts, up to moderate in eastern Liguria and Upper Tuscany. Strong winds are also expected in northern Sardinia, western Liguria, and southern Tuscany.

The Italian alert system for meteorological and hydrogeological risks is managed by the Civil Protection Department in collaboration with the Regions. Unlike general weather forecasts, these assessments have the specific purpose of identifying situations potentially harmful to people or property, such as floods, landslides, or inundations. The origin of this system dates back to the need to coordinate the response to extreme events at a national level, following a series of natural disasters that have affected Italian territory.

Each day, based on data collected from the national network of meteorological stations, radars, and satellites, the National Meteorological Vigilance Bulletin is produced. The Regions then assess possible critical issues in their territories, and these evaluations contribute to the National Criticality/Alert Bulletin. Finally, it falls to the Mayors of the affected Municipalities to activate municipal civil protection plans, inform citizens, and decide on concrete actions for the protection of the population. Today's yellow alert indicates an ordinary risk, requiring careful vigilance and the preparation of standard safety measures.
