Indonesia: Disruptions due to severe weather ongoing in parts of Bali Province as of July 11

Event

Disruptions due to severe weather are ongoing across parts of Bali Province as of July 11. Heavy rainfall and storms accompanied by strong winds July 7-10 have triggered widespread flooding, landslides, and property damage across the province. Affected areas include Badung, Bangli, Buleleng, Denpasar, Gianyar, Jembrana, Karangasem, Klungkung, and Tabanan. Authorities have reported at least five fatalities and seven others injured in weather-related incidents. More than 100 homes have been damaged, displacing around 192 people. Hundreds of others have also been left without safe drinking water. Although only isolated showers are forecast over the coming days, the Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG) has issued an early warning for strong winds in the region, especially along Bali's south coast.

Hazardous Conditions
Further sustained heavy rainfall could trigger additional flooding in low-lying communities near rivers, streams, and creeks. Coastal flooding is also possible during high tides. Urban flooding is also possible in developed areas with easily overwhelmed stormwater drainage systems. Sites located downstream from large reservoirs or rivers may be subject to flash flooding after relatively short periods of intense rainfall. Landslides are possible in hilly or mountainous areas, especially where heavy rainfall has saturated the soil. Power outages could occur throughout the affected area.

Transport
Floodwaters and debris flows may render some bridges, rail networks, or roadways impassable, impacting overland travel in and around affected areas. Ponding on road surfaces could also cause hazardous driving conditions on regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters.

The disruptive weather may cause delays and cancellations at regional airports. Flooding could block regional rail lines; freight and passenger train delays and cancellations are possible in areas with heavy rainfall and track blockages.

Disruptions triggered by inclement weather and resultant hazards, such as flooding, could persist well after conditions have improved - it could take days before any floodwaters recede and/or officials clear debris. If there is severe damage to infrastructure, repair or reconstruction efforts may result in residual disruptions.

Advice

Seek updated information on weather and related disruptions, including road conditions before driving or routing shipments through areas where severe weather is forecast. Plan accordingly for potential freight delivery delays if routing shipments by truck through the affected area. Do not attempt to drive through flooded areas. Charge battery-powered devices if prolonged electricity outages occur.
