Background:

Bekasi City Government declared a Disaster Emergency Status covering floods, extreme weather, and landslides effective from 25 July to 31 August, in response to ongoing sporadic heavy rainfall and natural hazard risks.

Impact:

The Jakarta region is anticipated to experience a mix of thunderstorms and cloudy weather throughout the week. If the weather deteriorates with more intense thunderstorms, the Jakarta region could face disruptions similar to those experienced during previous severe weather events.

Possible impacts include power outages caused by falling trees damaging overhead lines, lightning strikes impacting substations, and flooding affecting generation or distribution facilities. Such disruptions could lead to operational delays and impact businesses due to power supply disruptions.
