Meanwhile, a La Niña weather event will likely start in August or September 2016 and will continue into the last quarter of 2016, causing wetter than normal weather conditions. The Indonesia Weather and Meteorology Bureau (BMKG) predicts unusually high rainfall will continue until September 2016 in most of the country. Rainfall levels in Java, the eastern areas of Sulawesi, central Papua and southern Kalimantan and Sumatra may increase significantly by up to 200 percent. Current weather and the possible La Niña conditions increase the risk of more frequent and intense flood events and landslides. In the coming rainy season this may mean more causalities and damage, and may impact food access by disrupting travel networks and food storage, and health and nutrition status by higher risk of waterborne diseases.
