Genoa – After a strictly summer period from the meteorological point of view, Liguria is about to experience an unstable phase with locally strong showers and thunderstorms, in particular on the central sector of the region and the Po slopes.
Arpal therefore issued the yellow alert for thunderstorms in the morning, which will go off tomorrow, July 26, at 6, lasting until 15 (subject to new notices). The alert concerns the central part of the region, from Spotorno to Camogli, including the hinterland.
After a few weeks characterized by summer weather conditions with high temperatures (yesterday maximum of 33.4 in Riccò del Golfo, in La Spezia, highs above 30 degrees in Genoa and La Spezia) and rare rainfall, the region is preparing to experience a decidedly different meteorological phase .
Responsible for this change of scenery is a recess present on France: today Sunday 25 July, the southern humid flow that precedes it may give rise to showers and thunderstorms on the Po slopes, in particular the western one, and the central sector of the region weak precipitations were recorded between the Stura valley and the Genoese Ponente). The saccatura, then, will advance slowly from west to east, renewing and accentuating the conditions of instability with possible scattered showers or thunderstorms, even strong ones, in particular between the night and tomorrow morning, Monday 26 July. The phenomena are expected mainly on the center of the region and the Po slopes, and will diminish from the afternoon; the instability, however, will remain even between the night and the morning of Tuesday 27 July with possible thunderstorms, especially in the eastern center of the region.
