The National Building Research Organisation (NBRO) has issued critical Level III RED landslide warnings for 14 districts across Sri Lanka, effective from 16:00 hours on November 29, 2025, until 16:00 hours on November 30, 2025. The Landslide Early Warning Centre's alert covers major population centers and hill country regions where residents face immediate landslide risks.
Districts Under Red Alert
The comprehensive warning encompasses the following districts: Badulla, Colombo, Galle, Gampaha, Hambantota, Kalutara, Kandy, Kegalle, Kurunegala, Matale, Matara, Monaragala, Nuwara Eliya, and Ratnapura. This extensive coverage indicates widespread geological instability across both coastal and mountainous regions of the island nation.
Level III RED warnings represent the highest alert category in Sri Lanka's landslide warning system, indicating imminent danger to life and property. These warnings are issued when meteorological conditions combine with geological factors to create extremely hazardous situations for slope stability.
Understanding Landslide Risk Factors
Several factors contribute to increased landslide susceptibility in these districts. Heavy rainfall saturates soil layers, reducing friction between rock and earth formations. Sri Lanka's mountainous terrain, particularly in districts like Nuwara Eliya, Kandy, and Badulla, features steep slopes that become unstable when waterlogged.
The affected regions include both urban areas like Colombo and Gampaha, where construction activities may have altered natural drainage patterns, and rural hill country districts where deforestation and agricultural practices can destabilize slopes. Coastal districts such as Galle, Kalutara, and Matara face additional risks from erosion and heavy monsoon rains.
Immediate Safety Measures
Residents in warned districts should implement immediate safety protocols. Avoid staying in houses built on or near steep slopes, especially those showing signs of ground movement such as cracks in walls, tilting trees, or changes in water flow patterns. If living in vulnerable areas, relocate to safer ground immediately.
Monitor local weather conditions closely and stay informed through official channels. The NBRO recommends avoiding travel through mountainous areas during the warning period unless absolutely necessary. If travel is unavoidable, use main roads and avoid shortcuts through hilly terrain.
Establish emergency communication plans with family members and identify evacuation routes from your area. Keep emergency supplies including water, food, flashlights, and first aid materials readily accessible.
Warning Signs to Watch
Several indicators suggest imminent landslide danger. Ground movement signs include new cracks appearing in the ground, roads, or buildings, doors and windows sticking or jamming, and small landslides or rockfalls occurring nearby. Water-related warning signs encompass springs, seeps, or saturated ground appearing in previously dry areas, and rapid changes in creek water levels.
Environmental indicators include trees or utility poles tilting, unusual animal behavior, and sounds of cracking trees or boulders knocking together. If any of these signs appear, evacuate immediately and contact local authorities.
Historical Context and Preparedness
Sri Lanka experiences regular landslide events, particularly during monsoon seasons. The hill country districts of Kegalle, Ratnapura, and Nuwara Eliya have historically recorded significant landslide incidents causing casualties and property damage. The NBRO's early warning system has proven crucial in reducing fatalities through timely evacuations.
Climate change has intensified rainfall patterns, making accurate forecasting and early warning systems increasingly important. The current red alert reflects meteorological predictions of continued heavy rainfall combined with already saturated ground conditions.
Community Response and Support
Local authorities in affected districts have activated emergency response protocols. Disaster management committees are coordinating with police, military, and volunteer organizations to ensure public safety. Temporary shelters have been prepared in safer locations for potential evacuees.
Community members should support vulnerable neighbors, particularly elderly residents and those with mobility limitations. Share warning information through local networks and assist in evacuation efforts when necessary.
Recovery and Long-term Planning
Following the warning period, affected communities should assess property damage and report incidents to authorities. The NBRO will conduct post-event evaluations to improve future warning accuracy and effectiveness.
Long-term landslide risk reduction requires proper land use planning, slope stabilization measures, and maintaining natural drainage systems. Residents in high-risk areas should consider permanent relocation options and avoid construction activities that increase slope instability.
The current Level III RED warning demonstrates the importance of Sri Lanka's landslide monitoring system in protecting lives and property. Residents must take these warnings seriously and follow recommended safety measures until the alert period expires on November 30, 2025, at 16:00 hours.
