The National Building Research Institute (NBRO) has issued urgent landslide early warnings covering eleven districts across Sri Lanka, effective from 16:00 hours on September 25, 2026, through 16:00 hours on September 26, 2026. The warnings, classified at the highest alert level, signal significant danger for residents living in landslide-prone areas across a wide swath of the island. Authorities are urging communities in affected regions to remain on high alert, follow official instructions, and take immediate precautionary measures to safeguard lives and property.
Districts Under Landslide Early Warning
The NBRO has placed the following eleven districts under active landslide early warnings: Colombo, Galle, Gampaha, Hambantota, Kalutara, Kandy, Kegalle, Kurunegala, Matara, Nuwara Eliya, and Ratnapura. These districts span the Western, Southern, Sabaragamuwa, Central, and North Western provinces of Sri Lanka, reflecting the broad geographic reach of the current weather system driving heightened landslide risk. The sheer number of districts placed under warning underscores the severity of the meteorological conditions currently affecting the country.
Understanding the Level III Red Warning
Sri Lanka's NBRO operates a tiered landslide warning system designed to communicate varying degrees of risk to the public and relevant authorities. A Level III RED warning represents the most critical tier in this classification system, indicating that landslide activity is highly probable and that immediate action is required. This highest-level alert is issued when rainfall intensity, soil saturation levels, and geological conditions combine to create conditions where landslides are not merely possible but considered imminent or already occurring in specific locations.
When a Level III RED warning is in effect, Divisional Secretaries and their surrounding administrative areas are formally notified, enabling local government machinery to activate emergency response protocols. Residents in vulnerable zones are strongly advised to evacuate to safer ground without delay, avoid traveling near slopes, hills, and embankments, and stay away from rivers and streams that may experience sudden surges due to debris flows associated with landslide events.
Why These Districts Are at Risk
The districts named in this warning share common geographic and geological characteristics that make them particularly susceptible to landslides during periods of intense or prolonged rainfall. Districts such as Kandy, Kegalle, Nuwara Eliya, and Ratnapura are located within or adjacent to the central hill country of Sri Lanka, where steep terrain, fragile soil compositions, and dense human settlement on slopes create a volatile combination. Kalutara, Galle, and Matara along the southwestern and southern coastal belt also feature hilly interiors where heavy rainfall can rapidly destabilize slopes.
Colombo and Gampaha, while more urbanized, contain suburban and semi-rural pockets with elevated terrain that remain vulnerable. Kurunegala and Hambantota, though less frequently cited in landslide events, have been included in this warning cycle, suggesting that the prevailing weather system is delivering rainfall across an unusually wide geographic corridor.
Precautionary Measures for Residents
Residents living in or near landslide-prone areas within the warned districts should take the following precautionary steps immediately:
Evacuate if instructed: Do not wait for a landslide to begin. If local authorities or Divisional Secretariat officials issue evacuation orders, comply without hesitation. Move to designated relief centers or stay with family in safer, low-lying areas away from slopes.
Monitor warning signs: Be alert to early indicators of landslide activity, including unusual sounds such as cracking or rumbling from hillsides, sudden changes in water flow in nearby streams, new cracks appearing in the ground or walls of buildings, and tilting of trees or utility poles.
Avoid risky travel: Refrain from using roads that pass through hilly terrain, near cliff faces, or alongside riverbanks during the warning period. Landslides can block roads suddenly, and secondary slides can occur without warning.
Stay informed: Follow updates from the NBRO, the Disaster Management Centre (DMC), and official government communication channels. Warning levels can change rapidly depending on evolving rainfall patterns.
Prepare an emergency kit: Keep essential documents, medications, water, and food supplies ready for quick evacuation if circumstances demand it.
NBRO's Role in Landslide Risk Management
The National Building Research Institute serves as Sri Lanka's primary technical authority on landslide risk assessment and early warning dissemination. Operating under the Ministry of Housing and Construction, the NBRO continuously monitors rainfall data, geological surveys, and ground conditions to issue timely warnings that enable communities and government agencies to respond before disasters occur. Their early warning system has been credited with saving numerous lives in previous landslide events across the country's hill regions.
Stay Safe During the Warning Period
With Level III RED warnings active across eleven districts until 16:00 hours on September 26, 2026, the priority for all residents in affected areas must be personal safety. Sri Lanka's landslide history demonstrates that swift community response to official warnings dramatically reduces casualties. Authorities, community leaders, and residents must work together during this critical window to ensure that no lives are lost to preventable disaster. Stay alert, stay informed, and prioritize safety above all else.
