Yellow Alert Issued for Thunderstorms in Liguria as Weather System Approaches
Genoa, Italy – July 27, 2025 – The Ligurian region is bracing for a significant shift in weather patterns as Arpal, the regional environmental protection agency, has issued a yellow alert for thunderstorms. The alert is specifically targeted for the levante area (Zone C) and is in effect from 2 PM to 10 PM on Monday, july 28, 2025. While the probability of severe thunderstorms is contained within this specific zone, other parts of the region may also experience a chance of strong storms.
The forecast indicates an increase in cloud cover from the west throughout Sunday afternoon and evening, signaling the approach of a new weather disturbance. Experts predict showers and thunderstorms developing overnight, initially over central mountain areas, before extending to coastal regions and eastward. These storms could be intense and localized.
Cristina Capacci,a weather expert,described the event as a “rather rapid passage.” By Monday morning, the central areas of Liguria are expected to see a clearing. Though, eastern parts of the region may experience more persistent cloudiness with residual phenomena extending into the afternoon, particularly over the Apennine reliefs. The sea is also expected to be rough along the east coast due to long westerly waves, with other areas experiencing moderate sea conditions.
Liguria Weather Forecast – Key Highlights:
Sunday, July 27, 2025: Isolated showers or afternoon thunderstorms are possible, mainly moderating over mountainous areas, especially the Alps. Instability is expected to increase from late evening with the arrival of a new disturbance.
Monday, July 28, 2025: The night could bring scattered thunderstorms across central mountain reliefs, extending eastward and towards the sea, where they may be more persistent and potentially include hail. There is a high probability of strong and/or organized thunderstorms in Zone C, with a lower probability elsewhere.By Monday morning, phenomena are expected to diminish, but instability will persist, with possible showers or thunderstorms, especially in Zone C and over the reliefs of Zone A, with local extension to the coast. Locally strong winds (40-50 km/h) are forecast, with a northerly air mass and a very rough sea.
Tuesday, July 29, 2025: Locally strong northerly winds (40-50 km/h) are expected, with gradual attenuation throughout the day.

Current Weather Situation – July 28, 2025
As of 04:00 CEST, the Liguria region, specifically the Tigullio Gulf and Spezzina areas, is under a yellow weather alert due to the increasing risk of intense thunderstorms. The Italian Meteorological Service (Servizio Meteorologico) has issued warnings indicating a high probability of heavy rainfall, strong winds, and potential localized flooding. This Liguria storm is developing rapidly, fueled by warm, moist air moving inland from the mediterranean Sea.Residents and tourists in towns like Rapallo, Santa Margherita Ligure, Portofino (Tigullio) and La Spezia, Lerici, and Portovenere (Spezzina) should prepare for disruptive weather conditions.
Detailed Forecast for Tigullio Gulf
The Tigullio Gulf is expected to experiance the brunt of the storm between 06:00 and 12:00 CEST. key forecast details include:
rainfall: Accumulation of 50-80mm within a 6-hour period is anticipated, wiht peak intensities exceeding 20mm/hour. This level of rainfall poses a meaningful risk of flash floods in low-lying areas and along riverbanks.
Winds: South-easterly winds will strengthen to 60-80 km/h, with gusts potentially reaching 90-100 km/h, particularly along the coast.These strong winds could cause damage to trees,power lines,and coastal structures.
Sea Conditions: Rough seas are expected, with wave heights reaching 3-4 meters. Small craft are advised to remain in port. Coastal erosion is a concern with these conditions.
Affected Areas: Rapallo, Zoagli, Chiavari, Lavagna, and Sestri levante are particularly vulnerable.
detailed Forecast for Spezzina Area
The Spezzina area will likely see the storm’s impact slightly later, between 08:00 and 14:00 CEST. Forecast specifics:
Rainfall: Similar to Tigullio,40-70mm of rainfall is expected within a 6-hour timeframe,with intense downpours. The risk of river flooding is elevated, especially along the Magra River.
Winds: South-easterly winds will reach 50-70 km/h, with gusts up to 80 km/h. While slightly less intense than Tigullio, these winds still present a hazard.
Sea Conditions: Moderate to rough seas with wave heights of 2.5-3.5 meters. Maritime traffic should exercise caution.
Affected areas: La Spezia, Portovenere, lerici, and the surrounding inland areas are at risk.
Safety Recommendations & preparedness
The following precautions are strongly advised for residents and visitors in the affected areas:
- Secure Outdoor Objects: Bring inside or securely fasten any loose objects that could be blown away by the wind, such as furniture, umbrellas, and decorations.
- Avoid Travel: If possible,postpone non-essential travel during the storm. Roads may become flooded or blocked by debris. traffic disruptions are highly probable.

- Secure Boats: Boat owners should ensure their vessels are securely moored and protected from the wind and waves.
- Emergency Contacts: Keep emergency contact numbers handy (112 for general emergencies).
Ancient Weather Events in Liguria – Context & Risk
Liguria is prone to intense rainfall events, particularly during the autumn and winter months.However, summer storms, while less frequent, can be particularly damaging due to the region’s steep terrain and vulnerability to flash floods. In October 2018, severe flooding caused widespread damage and several fatalities in the region, highlighting the importance of preparedness. The 2018 Liguria floods serve as a stark reminder of the potential consequences of extreme weather. Understanding this weather history is crucial for effective risk management.
