Tomorrow, Friday 3 December, the bad weather it will move to the South as we can see from the maps of the Moloch model of the ISAC-CNR:
The storm front will first hit, in the morning, the lower Tyrrhenian Sea between southern Campania, Basilicata, northern Tyrrhenian Calabria and western Sicily, then extending to the whole South in the afternoon-evening, when strong thunderstorms with abundant rainfall will hit the whole of Calabria, and so particularly its central-southern Tyrrhenian belt, with storms on the Costa Viola, in the Reggio area, and in the Strait of Messina. Abundant precipitation with hail also on the Aeolian Islands. Snow will also return on the southern Apennine reliefs, at slightly higher altitudes than the premature snowfalls that have affected the low hills in recent days.
