Going back to the forecast, from today afternoon we will have the first rain, initially dispersed, then more widespread, even with a reverse or temporary character, possible throughout the region and more insistent in the central-eastern part: Sara snow inside (which affects the routes of the A6-A26-A7 highways), with decreasing snow levels with the passing of the hours and possible invasions in the central coastal sectors; in another place there will be rain.
The strengthening of the north winds over the central sectorIn fact, it will create conditions of convergence with those of the south that blow very intensely, especially towards the east: therefore, due to the north wind, until dawn snowflakes can be pushed towards the coast between Genoa and Savona.
