UNGRD reported that the affected area received 33 per cent of its monthly total of rainfall (130 mm of the 400-mm monthly average) on the night of the disaster.

Three aqueducts and the sewage system are affected, 10 roads are damaged, 2 bridges collapsed and 5 are being rehabilitated...Following an extraordinary meeting of the Cabinet at Nariño House, the Colombian government has assessed the catastrophe and the need to provide humanitarian assistance to the affected people and infrastructure investments to rebuild Mocoa and decided to declare an economic and social emergency.
