At least 13 people have died in Colombia following unusually heavy rainfall for this time of year, officials confirmed on Sunday. The National Meteorological Institute (IDEAM) reported that a fast-moving cold air mass from North America struck Colombia’s Caribbean coast, increasing rainfall by about 64 percent above the monthly average. The deadliest incident occurred in the southwestern Nariño province, where a landslide killed seven people after continuous rain caused a mountain stream to overflow and bury several homes under mud.

Video footage released after the disaster showed rescue workers using heavy machinery to clear debris and mud, while search dogs were deployed to locate missing persons. Earlier, on Thursday, the national disaster management agency UNGRD reported six additional deaths across various regions due to extreme weather conditions.

Meteorologists noted that climate change is disrupting Colombia’s traditional dry and rainy season patterns. Although the tropical country does not have sharply defined seasons, recent years have seen increasingly severe rainfall and drought events.
