On 11 September 2017, the Croatian city of Zadar and the surrounding area were affected by a mesoscale convective system producing extreme rainfall, which caused a flash flood.
Numerous houses, apartments and institutions were damaged, including Zadar cemetery, hospitals, roads and a shopping mall.
However, the Velebit mountain range extends along the coast behind Ravni Kotari, and caused the storms arriving from Tyrrhenian Sea in the west to undergo orographic lift and continually produce rain while passing over Zadar.
[4][9] The mesoscale convective system responsible for the flood spanned over 400 kilometres (250 mi) east–west, and reached a temperature of −65 °C (−85 °F) at the cloud tops.
[1] While the rainfall amount was extremely high, it did not break Zemunik's daily record of 352.2 mm (13.87 in), which was set during the flood of 11 September 1986.
