Genoa. The bad weather advances towards Valpolcevera and the Genoese west. Intense thunderstorms and lightning can be seen from the city center.
Meanwhile, a sea trumpet formed in Pegli just now, as seen in the photo of Carlo Besana. Last night a whirlwind, still in the west but in Voltri, almost uncovered the roof of the Pam, slightly injuring a child.
Heavy rain and thunderstorms in Valpolcevera.

We remember that theorange weather alert in Genoa and the center of the Region it will last until 18 today, to turn yellow until midnight.
Therefore, in the first part of today all the elements for the development of storms will be available strong, organized me stationary, in a context of generalized rains. Then, a temporary attenuation of the precipitation followed, already in the afternoon, by a new increase in the intensity of the phenomena.
Storm indices (which determine the degree of instability of the atmosphere and therefore the different forms of storms) are high, there will be a large availability of “precipitable water” (the “fuel” of the storms) and the probable convergences (that is, the contrasts between air masses characterized by different temperatures and winds from opposite directions) could trigger this stationarity capable of making it rain intensely in the same area for a few hours. Tomorrow, on the soil of Liguria, the sirocco will collide with the wind from the center-east, from the north to the west.
After a brief respite this afternoon, a new deterioration already at night, with the passage of the front proper expected in the night between Saturday and Sunday, accompanied by more widespread rainfall. A gradual improvement in the weather is expected to follow Sunday afternoon, albeit in the presence of residual instability. Attention also to the sea, which will increase on Sunday.
TODAY SATURDAY AUGUST 29: A disturbance crosses Liguria and brings widespread rains in the central Levant with significant accumulations in BE, up to high in C. The rains can take an inverse or storm character with probable strong phenomena in all areas, even organized and persistent in BCDE. Winds of 40-50 km / h from the southeast in the center of Levante with gusts and local reinforcements in C. Very rough sea even below the coast in C.
TOMORROW SUNDAY AUGUST 30: The disturbance continues in Liguria, causing heavy rains and thunderstorms in all areas overnight. Exhaustion phenomena during the morning from the West. Since the afternoon, rough seas locally at the ends of A and B, also along the coast at C; Southwest winds 40-50km / h with reinforcements and gusts.
