Genoa. As expected these days, the weekend a sharp deterioration of weather conditions is on the way, with the arrival of an imposing disturbed front, which will generate strong and concentrated rains per character storm in much of our region.
For this reason Barley has issued the warning of showers and thunderstorms with the following hourly scan: throughout the region excluding the extreme west, which is the Imperia area, the alert will be YELLOW from midnight on Saturday, August 29 to 6, when it will rise to ORANGE until 6pm. Then it will be yellow again until midnight. As for the province of Imperia, it will be yellow from midnight to midnight.
Emphasizing like orange is the highest degree of warning for thunderstorms, Please note that the assessments for Saturday night and Sunday will take place late tomorrow morning – follow the updates.
The worsening has characteristics typically fall: a deep low depression moves from Great Britain to France, extending its action into the central Mediterranean and causing an accentuated call of hot and humid air from North Africa to Liguria.
So in the first part of tomorrow 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 tomorrow afternoon, a new deterioration already in the afternoon, 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, FRIDAY, AUGUST 28: Physiological heat discomfort in poorly ventilated urban centers and internal valleys. Weak instability with possible showers or thunderstorms of moderate intensity at most, most likely in the center-west. South winds 40-50km / h with reinforcements and gusts 60-70km / h on the ridges.
TOMORROW 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.
AFTER TAKING 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.
