Overview

• A large cyclonic vortex near France is driving unstable oceanic air masses into Italy, causing widespread atmospheric instability.
• Rain, thunderstorms, and hail will first impact Sardinia and the Northwest, including lower Piedmont and Liguria, before intensifying over northern mountains and the Apennines by morning.
• Severe weather is expected to spread to plains and central-southern regions, with Tuscany, Marche, Umbria, Abruzzo, Molise, Basilicata, Calabria, and Sicily all affected by afternoon and evening.
• Northern regions like Piedmont, Lombardy, Emilia-Romagna, and Triveneto are at risk of strong storms with wind gusts and localized hail.
• Weather conditions are expected to improve later today in Sardinia, Sicily, and along the Tyrrhenian coast, with a more sustained respite forecast for the weekend.
