Severe flooding triggered by torrential rains between has killed at least six people in Bali, Indonesia on September 9 and 10. The floods inundated large areas of Denpasar and surrounding regencies, collapsing several buildings, blocking key roads, and forcing the evacuation of hundreds of residents.

In Denpasar, four people were killed when two buildings collapsed amid rising floodwaters. Another two fatalities were reported in Jembrana Regency, where at least 85 people were evacuated to temporary shelters. The National Search and Rescue Agency (Basarnas) deployed around 200 personnel to assist evacuations and search operations.

Among the fatalities was a pregnant woman who was swept away by floodwaters while riding a motorcycle. In another incident, a three-story building along the River Badung collapsed, leaving several family members unaccounted for.

Local officials reported water depths of 2–3 m (6.5–10 feet) in several neighborhoods. Rubber dinghies were used to reach stranded residents, and parts of the main access roads to Ngurah Rai International Airport were submerged, leaving passage only for heavy vehicles.

The neighboring province of East Nusa Tenggara also reported at least four fatalities due to similar flooding.

The Meteorology, Climatology and Geophysics Agency (BMKG) attributed the event to atmospheric Rossby waves, a planetary-scale atmospheric disturbance that propagates along the equator and can intensify convection and rainfall in the tropics. 

BMKG warned that unstable weather conditions are likely to persist for several more days as the wave continues to influence the region.
