Tonight\'s Serie A match between Atalanta and Genoa has been postponed due to heavy snowfall in Bergamo. Snow has fallen intermittently in the northern city throughout the day and the referee, having initially delaying the kick-off by one hour, finally decided the pitch at the Atleti Azzurri d\'Italia stadium was unplayable shortly before 19.00 local time. A statement from Atalanta read: \"For safety reasons, the game between Atalanta and Genoa has been postponed.\" This is the fourth fixture this week to be called off because of the ongoing bad weather in northern Italy, where night-time temperatures are expected dip below minus ten degrees centigrade in the coming days. Earlier today, matches at Bologna and Siena scheduled for this evening also fell foul of the elements. Bologna were due to host Fiorentina at the Renato Dall\' Ara stadium, while Siena were set to face Catania at the Stadio Artemio Franchi. Yesterday\'s match between Parma and league leaders Juventus was also called off due to heavy snow. New dates for the fixtures have yet to be confirmed. Tonight\'s remaining fixtures at Cagliari, Inter Milan, Lazio, Napoli and Udinese are all set to go ahead, along with tomorrow\'s encounter between Novara and Chievo.
