Torrential rains that began on 09 September, have caused flash floods and landslides on Bali. At least 9 people have died, and around 600 have been affected. Major roads are blocked, disrupting traffic, while tourism businesses and traders have suffered losses. The Meteorology, Climatology and Geophysics Agency (BMKG) reported more than 150 millimeters of rain in a single day, triggered by the Rossby equatorial wave, which are very long, slow-moving waves in the atmosphere and oceans that help to regulate weather and climate. The BMKG warned that extreme weather could persist for three more days. Experts say frequent flooding in Bali is linked to climate change, overtourism and overdevelopment. Rescue efforts continue, hindered by severe weather and difficult terrain.
