Genoa sits in central Italy’s hilly Apennine terrain, where a Mediterranean-to-continental transitional climate produces its heaviest rain in autumn, sometimes concentrated into short, intense, and highly localized storms.
Built along a narrow strip between steep hills and the Ligurian Sea, the city has one of Italy’s most severe flash-flood histories, including deadly events in 2011 and 2014. The steep, closely-spaced valleys typical of this part of Italy mean small rivers can rise dramatically within hours, a pattern that has produced serious floods here in past decades, and radar remains one of the best tools for anticipating it.
