The National Building Research Organization (NBRO) has issued critical Level III landslide early warnings for six districts in Sri Lanka, effective from 4:00 PM on December 1, 2025, to 4:00 PM on December 2, 2025. The affected districts include Badulla, Kandy, Kegalle, Kurunegala, Matale, and Nuwara-Eliya, areas known for their mountainous terrain and vulnerability to landslide incidents.
Understanding Level III Landslide Warnings
Level III landslide warnings represent a significant threat level in Sri Lanka's early warning system. These warnings indicate that conditions are highly favorable for landslide occurrence, requiring immediate attention and precautionary measures from residents in affected areas. The NBRO's landslide early warning centre continuously monitors geological and meteorological conditions to provide timely alerts that can save lives and property.
When Level III warnings are issued, it means that recent rainfall patterns, soil saturation levels, and geological conditions have reached critical thresholds. These factors combined create an environment where landslides are not just possible but probable, making evacuation and safety measures essential for vulnerable communities.
Districts Under High Alert
The six districts currently under Level III warnings are among Sri Lanka's most landslide-prone areas due to their topographical characteristics and weather patterns.
Badulla District encompasses much of the central highlands and has experienced several significant landslide events in recent years. The district's steep slopes and heavy seasonal rainfall make it particularly susceptible to soil instability.
Kandy District, home to the cultural capital, features numerous hilly areas where residential communities are built on slopes. The combination of urban development and natural terrain increases landslide risks during heavy rainfall periods.
Kegalle District has historically been one of the most landslide-affected areas in Sri Lanka. The district's geology, combined with intensive agricultural activities on slopes, creates conditions conducive to landslides.
Kurunegala District contains both flat areas and hilly regions, with the elevated areas being particularly vulnerable during monsoon seasons and periods of intense precipitation.
Matale District is characterized by its mountainous terrain and is situated in a region that receives substantial rainfall, especially during the northeast monsoon period.
Nuwara-Eliya District, known for its tea plantations and cool climate, sits at high elevations where steep slopes and saturated soils can quickly become unstable during heavy rains.
Safety Measures and Precautions
Residents in the affected districts should take immediate precautionary measures to ensure their safety. First and foremost, those living in slope areas, near cut slopes, or in areas with previous landslide history should be prepared for possible evacuation.
Monitor weather conditions closely and pay attention to official announcements from local authorities and disaster management agencies. Heavy rainfall, especially continuous rain over several hours, significantly increases landslide risk.
Identify safe locations away from slopes, valleys, and areas where water naturally collects. These safe zones should be easily accessible and known to all family members. Keep emergency supplies ready, including water, non-perishable food, flashlights, batteries, and important documents in waterproof containers.
Watch for warning signs of potential landslides, such as cracks appearing in walls or ground, unusual sounds like rumbling or cracking, sudden changes in water flow patterns, or tilting of trees, utility poles, or structures.
Government Response and Support
The NBRO's early warning system represents a crucial component of Sri Lanka's disaster risk reduction strategy. By providing advance notice of potentially dangerous conditions, authorities can coordinate evacuation efforts and deploy emergency resources where they are most needed.
Local government officials in the affected districts are likely coordinating with disaster management committees to ensure emergency shelters are prepared and evacuation routes are clear. Emergency services, including police, fire departments, and medical facilities, are typically placed on high alert during Level III warnings.
Climate and Seasonal Factors
The timing of these warnings coincides with Sri Lanka's northeast monsoon season, which typically brings heavy rainfall to many parts of the island. December is often a critical month for landslide activity due to the combination of monsoon rains and already saturated soil conditions from previous precipitation.
Climate change has intensified weather patterns in Sri Lanka, leading to more frequent extreme rainfall events that can trigger landslides. This makes early warning systems increasingly important for protecting vulnerable communities.
Residents in the warned districts should remain vigilant throughout the warning period and continue monitoring official channels for updates. The 24-hour warning period allows sufficient time for preparation and evacuation if necessary, but swift action may be required if conditions deteriorate rapidly.
