BMKG: Waspada Bencana Banjir & Longsor dari Januari - Februari 2025 - [METRO SIANG]

Summary

In this interview, the head of BMKG, Dwi Korita Karnawati, explains the ongoing heavy rainfall in Indonesia, caused by the strengthening Asian monsoon, weak La Niña conditions, and other meteorological phenomena like the Kelvin and Rossby waves. These factors contribute to increased cloud formation and extreme rainfall, raising the risk of floods and landslides, particularly in areas with environmental degradation. BMKG warns of continued wet conditions until March or April and urges the public to monitor weather updates through official channels. Some local governments have also considered weather modification to manage the impacts.

Takeaways

• 🌧️ The rainy season in Indonesia has intensified, with frequent and heavy rainfall leading to flooding in several regions.
• 🌦️ The Asian Monsoon, which began in November, has reached its peak in January and February, causing heightened rainfall across much of Indonesia.
• 🌍 A weak La Niña event is contributing to the abnormal weather conditions, predicted to persist until March or early April.
• 🌬️ The onset of cold air from Siberia and the Kelvin and Rossby waves are amplifying cloud and rain formation in the region.
• 🌀 These combined phenomena have created a complex situation, with heavy rainfall and strong winds that are increasing the risk of disasters.
• 🚨 Indonesia is experiencing its peak rainy season, particularly in northern Java, Jakarta, Central Java, East Java, NTB, and parts of Kalimantan, expected to last until the end of February.
• 🌊 Areas with degraded landscapes or deforested regions, especially those with sediment buildup in rivers and lakes, are at heightened risk for landslides and floods.
• 💨 Localized weather modifications, such as cloud seeding, are being implemented in several provinces, including Central Java, East Java, and Lampung, to mitigate extreme weather effects.
• 📊 The public is encouraged to stay updated on weather changes using the BMKG mobile app and website for real-time weather warnings and forecasts.
• 📅 The risk of extreme weather will continue to shift across different regions, with forecasts updated every 3 hours for specific districts and provinces, allowing for timely actions.
• 💡 Awareness and vigilance are crucial, as weather patterns can change quickly, making it essential for local governments and citizens to monitor and respond to warnings from BMKG.

Q & A

What is the main reason for the heavy rainfall occurring in Indonesia?

The heavy rainfall is primarily caused by the peak of the Asian monsoon season, which began in November, and is now at its strongest in January and February. Additionally, the weak La Niña phenomenon and other atmospheric patterns are intensifying the rainfall.

When did the Meteorological, Climatological, and Geophysical Agency (BMKG) predict the rainy season would start?

BMKG predicted that the rainy season would begin in November, with the peak of rainfall expected in January and February, and that it would end around March or April.

What environmental factors contribute to an increased risk of flooding and landslides?

Factors like deforestation, sedimentation in rivers and lakes, and disruption of natural landscapes increase the risk of flooding and landslides. These environmental disturbances make it easier for erosion to occur and for slopes to become unstable during heavy rainfall.

What role does La Niña play in the current weather conditions?

La Niña, which began in November, is contributing to the intensification of rainfall. It is a natural climate phenomenon that can enhance the effects of the monsoon, leading to heavier and more frequent rainfall in certain areas.

How long is the expected duration of the current rainy season?

The rainy season is expected to last until March or April, with the peak intensity occurring from January to February.

Which areas in Indonesia are expected to experience the most severe weather conditions?

Areas that are expected to experience the most severe weather conditions include parts of Java, Bali, NTB, NTT, Kalimantan, and Sulawesi. These regions are at high risk for floods and landslides due to the heavy rainfall.

What has the Indonesian government done to mitigate the impact of heavy rainfall?

The government has conducted weather modification efforts, such as cloud seeding, in various provinces like Java, Kalimantan, and Lampung to manage the extreme weather and reduce the intensity of rainfall.

How can the public stay informed about the changing weather conditions?

The public can stay informed by regularly checking updates on the BMKG website and mobile app. These platforms provide real-time information on weather conditions, including potential dangers such as floods and landslides.

Why is it important for people to monitor real-time weather updates?

It is crucial to monitor real-time updates because the weather conditions can shift rapidly. The location of potential hazards, like heavy rainfall or flooding, can change frequently, so timely information is essential for public safety.

What is the potential risk if environmental degradation continues in vulnerable areas?

If environmental degradation continues, the risk of disasters such as landslides, floods, and flash floods will increase. Unprotected slopes and riverbeds will be more susceptible to erosion, especially during intense rainfall.
