United Nations Office for the Coordination of Humanitarian Affairs (OCHA) reports that approximately 25,000 people have been affected by heavy rain and flooding the department of Nariño, Colombia.
A total of eight rivers have burst their banks since early January 2017. River levels have since returned to normal and according to Colombia’s Instituto de Hidrología, Meteorología y Estudios Ambientales (IDEAM), as of 03 February there were no alerts for any rivers in any parts of the country. However, there is a red level warning in place until 06 February for landslides in unstable areas in Barbacoas as a result of possible heavy rain.
OCHA reports that flooding has damaged homes, crops and livestock and affected at least 8 municipalities of Nariño department, situated in the west of the country bordering Ecuador and the Pacific Ocean.
One of the worst hit areas is the municipality of Olaya Herrera, where 11,360 people have been affected after the Sanquianga river overflowed.
Some of the worst flooding has also affected the municipality of Arboleda, where 65 houses have been damaged and 5 destroyed after the Quebrada Las Palmas overflowed.
Over 3,700 people have been affected in Barbacoas where the Telembí river burst its banks on 20 January. The Telembí has also flooded in parts of Roberto Payán, affecting 4,655 people.
