Orange alert, danger still lurking: "There are ingredients for self-healing storms"

Genoa. Liguria in the dry or almost in the first hours of orange weather alert, while in the hinterland we live the terror of a new wave of destruction after theflood in the Stura valley and in the lower Piedmont. The vast temporal front that crosses the Mediterranean from west to east has especially touched the Ligurian West, with an isolated reverse in Testico, in the Savona area, which produced no consequences.

"For the moment everything is concentrated in Corsica, but the next few hours will be crucial – explains Federico Grasso from the Arpal weather center – the front is passing through the center of the region and begins to feel the effects of high pressure, a vortex is created due to the low pressure on the Ligurian Sea and so the conditions of stationary can be verified " . In less technical terms, the key will once again be the wind (sirocco or dry ostro) which could push rainfall further north.

But they can "light up" again self-regenerating cells like the one that flooded the Stura valley? "The ingredients in the atmosphere are all there – assures Grasso – someone is more pushed, someone less, we'll see how they go together. Fortunately, at the moment it is a fast passage. However, in the Ligurian Sea phenomena similar to those of Monday can be formed at any time, both in the West, both in the center and on the Levant ”.

At the moment i levels hydrometric in the main watercourses they have remained substantially stable, or show in these hours that they do not reach the full levels. THE twenty they are moderate or locally northern strong in Ponente, in partial attenuation in the last two hours, while in Centro-Levante they blow from East / South-East with intensity up to strong, locally stormy on the reliefs (maximum burst 96 km / h at Fresh Fountain).
