Colombia: Widespread risk of flooding continues /update 12
Deadly rains continue to wreak havoc in large areas of western and central Colombia; various departments on alert for flooding as of May 9
Event
Torrential rains continue to wreak havoc in large areas of western and central Colombia, resulting in flooding and deadly landslides. As of Tuesday, May 9, red alerts for flooding (the highest level) issued by the national meteorological authorities IDEAM are in effect for municipalities across numerous departments: Antioquia, Caldas, Chocó, Córdoba, Cundinamarca, Guaviare, Santander, and Tolima. Lesser orange and yellow alerts are in place across various other zones.
Generally speaking, the flood risk is highest along rivers and other bodies of water. No areas are currently under landslide alerts, but this could change in the coming hours or days.
An increased risk of traffic accidents and ground transportation disruptions are to be anticipated in the coming days and weeks as many roads and bridges have been washed away or rendered temporarily impassable.
Context
Weeks of torrential rains, the worst seen in the country for the past six years, have resulted in major destruction in large areas of the country, notably deadly landslides in Mocoa (April 1; more than 320 killed), Manizales (April 19; at least 19 deaths), Bagadó (April 20; two deaths), and Cocorná (May 1, three deaths).
Flooding and landslides are common during the rainy seasons which typically occur April-May and October-November. The current rainy season has been more intense than usual due to the cyclical climatic phenomenon La Niña.
Be aware that the risk of contracting water- and mosquito-borne diseases, including malaria, chikungunya, dengue fever, yellow fever, and the Zika virus, tends to rise after periods of heavy rains.
Advice
Individuals present in affected departments are advised to keep abreast of the situation, to avoid areas directly hit by flooding, and to adhere to any orders issued by the local authorities. Remember that driving or walking through running water can be dangerous – 15 cm (6 in) of running water is enough to knock over an adult – and that floodwater may contain wastewater or chemical products; all items having come into contact with the water should be disinfected and all foodstuffs disposed of.
