Snow warning in Genoa and Liguria on Wednesday 8 December 2021
Feast of the Immaculate Conception under the banner of bad weather in Liguria. As anticipated, precipitation is expected, even snowy ones, with some flakes that could also reach the coast between Genoa and Savona. Arpal has issued the weather warning for snow. The details:
- internal municipalities of zones A and B (west and center of the region): yellow from 8 to 18
- coastal municipalities of zone B: yellow from 10 to 15
- zones D and E (western and eastern Po slopes): yellow from 5 to 8 then orange until 15 then again yellow until 20.
After two sunny but rather cold days, the high clouds expected for the afternoon will herald the imminent change of weather conditions on Liguria. An Atlantic perturbation, in fact, will cause, already from the early hours of Wednesday 8 December, widespread and persistent weak rains with some local downpours.
The most important phase of the worsening is expected between the morning and the afternoon, with a thermal collapse that will cause snow in inland areas with a lowering of the snow level on the Po slopes and in the inland areas of the central sector and phenomena that will push behind of the coast, up to hilly shares; it is not excluded, where the orography and the thermal conditions of the air column will allow it, that you can reach the coast between the Genoese and Savona areas.
The accumulations will be substantial in the interior with particular attention, therefore, for the areas crossed by the motorway routes. In addition to the snow, the storm wind will be the protagonist, from sirocco to Levante, while there will be a north wind over the central Ponente. For a gradual attenuation of the phenomena it will be necessary to wait for the late afternoon and evening hours; the evening clearing up will cause a marked drop in temperature and may cause widespread and intense frosts in inland areas.
Meanwhile, last night’s temperature outlined an icy scenario in the regional hinterland: -8.7 in Cabanne (Rezzoaglio, Genoa), -7.6 in Calizzano (Savona), -7.4 in Ferrania (Cairo Montenotte, Savona), -6.9 in Sassello (Savona), -6.6 in Loco Carchelli (Rovegno, Genoa), -6.4 in Pratomollo (Borzonasca, Genoa), -6.1 in Colle di Nava (Imperia), -5.7 in Diga del Brugneto (Genoa) and Cairo Montenotte (Savona) , -5.5 in Murialdo (Savona) while, in the La Spezia area, the minimum was -5.2 in Padivarma (Beverino).
