Footage shows torrents of water from the DANA storm gushing over a weir at the Rio Seco in Castellon, Spain, on the morning of October 31.

Heavy rain caused carnage with severe floods across the region this week.

The State Meteorological Agency has issued a red alert for the eastern region of Valencia, with areas such as Turis and Utiel recording 200 mm (7.9 inches) of rainfall.

Officials have reported 158 fatalities attributed to the destructive weather system, which occurs when cold and warm air converge to create rain clouds. This event is thought to be becoming more common due to climate change.

This phenomenon is referred to locally as DANA, a Spanish acronym for high-altitude isolated depression. Unlike typical storms, it can develop independently of polar or subtropical jet streams.
