Bad weather warning. The weekend opens under the banner of a typically autumnal variable climate, characterized by storm fronts alternating with clearings. The temperatures, in extremis, seem to recover the long-awaited "St. Martin's Summer".
Severe weather alert
The Department of Civil Protection predicts intense rain and thunderstorms, with the risk of hailstorms, lightning and strong gusts of wind in regions such as Tuscany and Lazio. The orange alert has been declared for the hydrogeological risk over north-western Tuscany, while the rest of the region and 10 other regions, including Umbria, Calabria, Sicily, Abruzzo and Molise, are on yellow alert.
The tradition of “St. Martin's Summer” remembers the military noble St. Martin, who, according to legend, gave half of his cloak to a poor man during a cold autumn day, leading to a sudden return of summer weather. Meteorologists explain this phenomenon with the autumn expansion of theanticyclone from Spain towards the Mediterranean, leading to high pressure, high temperatures and favorable weather conditions.
