A developing weather pattern is bringing the potential for thunderstorms and heavy rainfall to Corsica on Monday, particularly in the late afternoon and into the night. The eastern coast of the island is under closer watch, as the storms are expected to bring significant rainfall, though the most intense activity is likely to occur at sea. These thunderstorms could lead to localized heavy rain and runoff in certain areas. The first thunderstorms are anticipated to form this afternoon along Corsica’s eastern coast, specifically between Porto-Vecchio, Fium'Orbu, and the Castagniccia region. As the day progresses, the weather is expected to worsen with the arrival of new storm systems from the Tyrrhenian Sea. The risk of heavy rain is most significant along the eastern coast between Monday evening and Tuesday morning. These thunderstorms may remain in place, leading to intense, short-lived rainfall bursts. Forecasts predict 30 to 60 mm of rain in affected areas, with some spots possibly receiving over 100 to 150 mm by Tuesday evening, though the exact locations of these heavy rains remain uncertain. The weather in Corsica began the day relatively clear, but conditions are expected to deteriorate throughout Monday. Both departments of the island are under a yellow alert for thunderstorms and rain-related flooding, effective from 2:00 PM and expected to remain in place until at least Tuesday evening. In Southern Corsica, the first showers may begin as early as the morning in areas like Alta Rocca and Porto-Vecchio. By the afternoon, High Corsica is also expected to see worsening conditions, with the sky darkening and the risk of rain spreading across the region. Showers are likely to continue through the night, with some areas experiencing more frequent rainfall. However, the highlands and northwest of Southern Corsica may see an improvement in the latter part of the night. While no specific alerts have been issued, the situation requires careful monitoring due to the potential for very localized and intense rainfall. Forecasters caution that the exact path and intensity of the thunderstorms could change depending on how the storm cells develop in the coming hours. Residents and visitors are advised to remain cautious, especially near rivers, the coast, and during activities that are sensitive to weather changes.
