DENPASAR, Bali — Indonesian weather authorities have issued an urgent warning for extreme weather across Bali on Monday, as heavy to very heavy rainfall and strong winds are expected to affect much of the island, raising the risk of flooding, landslides, fallen trees, and dangerous sea conditions.
The alert was released by the Meteorology, Climatology, and Geophysics Agency (BMKG), which said the conditions are being driven by unstable atmospheric dynamics, including the influence of a developing tropical cyclone seed south of Indonesia.
The warning applies island wide, with heightened concern for coastal areas, low lying urban zones, and mountainous regions.
Heavy Rainfall and Strong Winds Expected
BMKG forecasts intense rainfall, in some areas classified as very heavy and accompanied by lightning, throughout the day. Strong and potentially damaging winds are also expected, increasing the likelihood of fallen trees and structural damage, particularly in areas with saturated soil.
Several parts of Bali, including Denpasar and Badung, experienced flooding on Sunday, a sign that drainage systems in some urban and tourist heavy areas are already under strain.
High Risk Areas for Residents and Travelers
Authorities are urging residents, tourists, and expatriates to exercise extreme caution, especially in the following zones:
- In urban and low lying areas, including parts of Denpasar and Badung such as Kuta, Seminyak, and Canggu, heavy rain may trigger sudden flooding and traffic disruptions.
- In mountainous and highland regions, including Bangli, Karangasem, Bedugul, and parts of Buleleng and Tabanan, prolonged rainfall significantly increases the risk of landslides along steep slopes and roads.
- Areas with large roadside trees, including sections of Ubud and major arterial roads, face an elevated risk of falling trees due to strong winds and waterlogged soil.
- All coastal and marine zones around Bali are under special watch. BMKG has warned of high waves potentially reaching 2.5 to 4 meters in certain waters, affecting ferry crossings and small vessels, including routes to Nusa Penida, Nusa Lembongan, and Lombok.
Travel and Sea Activities Strongly Discouraged
Officials advise postponing non essential travel, particularly long distance road trips and all sea crossings. Activities such as swimming, surfing, diving, and boating are strongly discouraged until conditions improve.
Road access to ports such as Gilimanuk and Padang Bai, as well as inland tourist routes to destinations like Jatiluwih and Kintamani, may be disrupted by flooding, fallen trees, or landslides.
Safety Guidance for Tourists and Expats
Authorities emphasize preparedness during the extreme weather period. Travelers and residents are encouraged to remain indoors when possible, ensure mobile phones are fully charged, keep power banks and flashlights available, and follow updates from official sources.
People are also advised to avoid sheltering under trees, billboards, or near unstable power lines during storms. Those living near rivers or slopes should remain alert for early signs of flooding or ground movement.
A Test of Seasonal Resilience
As Bali enters the peak of its rainy season, officials warn that weather driven disruptions are likely to continue in the coming days. While the island remains open to visitors, safety authorities stress that caution and situational awareness are essential.
For travelers and expatriates alike, the message from authorities is clear: adjust plans, stay informed, and prioritize safety over schedules.
