During the second half of the forecast period, a secondary cyclogenesis forms over bay of Genoa as a response to rapid height falls over relatively warm Mediterranean waters. Quite strong wind field accompanies this low, while it slowly moves towards central Italy. At least marginal instability will form mainly over the seas, while being within the moderately sheared environment. Expect some better organized storms mainly along the cold front, some of them may be severe and support excessive convective rain. Intensifying LL wind field around the low centre could result in some strong winds with the storms as well. Rather slow moving system and storms could cause some local flash floods. A level 1 has been issued to cover this threat.
