In the Wednesday bulletinwe had issued an alarm for flood scenarios in the north-west, Liguria included. Yesterday, thanks to the modeling chaos, possible less worrying scenarios seemed to be opening up, then the original forecast regained its footing and seems to have materialised. Start one today three days extremely worrying. Modeling offers disturbing maps.
As I expected Arpal Liguria has correctly issued a yellow alert status on tomorrow Genovese and orange a Levante (also given the saturation of the land in the eastern part of the Region) our province is green as the disturbances will still be rather limited and contained. If the forecast framework remains rather complex, it is also likely that the conditions for the day after tomorrow and on Sunday seem destined to worsen further and also significantly involve the Imperia area. Beyond Liguria, focus on Piedmont, especially central western Italy, in short, situations that do not leave you at peace. Furthermore, the main problem will be the duration of the event and the stationarity of the phenomena due to the usual anticyclonic block positioned to the east which will slow down, if not even prevent, the flow towards the East.
The estimates rainfall measurements, returning to talk about Liguriathey are triple digits but triple digits and rising. Very important values will have an impact on an area already put to the test. In this bulletin I won’t go into too much detail, I’ll leave it until tomorrow. Obviously the positioning of the minimum depression will be decisive. At the moment the most dangerous situations dance between Imperia, Savonese e Genovesato. The main anomaly concerns the pressure. Naturally, the most attentive will have noticed that the barometers on the ground are particularly high, but it is necessary to take into account the retrograde movement of the old disturbance which passed through in recent days and which is moving up the Peninsula and which brings a very humid air mass at altitude which, interacting with the lower hp will favor heavy rainfall as happened for example in Tuscany last night. Given the uncertainty, it is impossible to go any further at the moment, however a minimum amount of exposure is necessary otherwise, as I always say, those who read the forecast must be told to open the window in the morning and make it themselves.
In summary: tomorrow in the Imperia area a day with instability and transitory disturbances, possible/probable worsening starting from 12:00 without however particular problems. On Saturday the phenomena intensified around 12:00. The alert scenarios are all completely open and in the central western part of the Region they can oscillate between yellow and red. Indicatively for Saturday, yellow alert for the Imperia area, orange starting from Capo Mele up to eastern Savona and western Genovesato. By Sunday, possible transition to orange in the Imperia area (pay attention to the extreme of the province, Ventimiglia where a fully red scenario emerges on the very nearby Côte d’Azur), possible further raising of the state of alert from Capo Mele up to the Center of the Region. Levante much more sheltered on Saturday and Sunday. If this line is confirmed, hydrogeological criticalities are expected throughout the central west. See you tomorrow with the hope that the cards will change for the better and reduce the extent of the rains.
