Yellow weather alert for thunderstorms in the South and Sicily on October 25th

The Civil Protection Department has issued a yellow weather alert bulletin for tomorrow, Sunday, October 25, 2026, due to the risk of thunderstorms and hydrogeological instability. The affected regions are Molise, Apulia, and Sicily, particularly the coastal areas and Tyrrhenian sectors.

The bad weather is caused by the tail end of a disturbance linked to storm 'Boelo', which is passing over Northern Europe and will graze central-northern Italy. Widespread rainfall, including showers or thunderstorms, is expected across Abruzzo, Molise, the Gargano area of Apulia, and northern Sicily, with cumulative amounts ranging from weak to moderate.

The Civil Protection also forecasts strong northwesterly winds over Sardinia, Sicily, and Calabria, and very rough seas in the western and southern basins. Citizens in the affected areas are advised to consult the bulletins and follow the instructions of local authorities.

The Italian weather alert system is managed by the Civil Protection Department, which prepares the National Meteorological Vigilance Bulletin daily. This bulletin is not a simple weather forecast but highlights situations potentially harmful to people or property, with the aim of preventing risks.

The process begins with weather forecasts for civil protection purposes, prepared by the Regions and the Department. Based on the predicted events, each Region and Autonomous Province assesses possible situations of hydraulic and hydrogeological criticality, such as floods, landslides, and inundations. These assessments feed into the National Criticality Bulletin, which is produced daily.

It is then the responsibility of the Regions to issue alerts to the local civil protection systems. Once they receive the alert, Mayors must activate municipal plans, inform citizens, and decide on actions to protect the population. The yellow alert, such as the one issued for October 25th, indicates an ordinary risk, the first level of criticality, which nevertheless requires attention and consultation of official bulletins.
