Valencia lies flat around a riverbed on an alluvial plain , which places it at high risk of flooding. When heavy rains coincide with a convective storm during which the sea level tends to rise, the flow is especially disturbed and flood risk is doubled. The areas where it rained the most have not been flooded, but those whose geography is more predisposed to accumulate water, like the peripheral municipalities, but not the city center, where the old riverbed was made into a park, the Turia Garden in 1986. ^[ 9 ]

The second morphological feature are the mountains of the Tertiary period . ^{[ 10 ] : 2} Blocked from the continent by the cliffs, the clouds rapidly precipitate. ^{[ 10 ] : 4–5} The town Oliva south of Valencia for example has experienced 20 intense floods after 1972. ^{[ 10 ] : 3}

The third factor is the intense urbanization of the coastal area. Impervious surfaces (such as roads and buildings ^{[ 10 ] : 5} ) prevent water from penetrating the ground. ^{[ 10 ] : 12} Water pools on level land, ^{[ 10 ] : 17} and is further retained by the metre-high beach ridge . ^{[ 10 ] : 11} When runoff is prevented and water gathers, flash flooding results. ^{[ 10 ] : 15} Rising sea levels will further increase the drainage time to days or even weeks. ^{[ 10 ] :21}

From 1997-2007 there was intense construction activity, which proved non-sustainable. ^{[ citation needed ]} The unusually high temperature of the seawater after the 2024 summer facilitated the generation of clouds of great vertical travel.
