Sri Lanka landslide warnings cover four districts as heavy rain raises river levels and strong winds create dangerous sea conditions.
Sri Lanka landslide warnings have been issued for four districts as heavy rainfall, rising river levels and strong winds increase weather-related risks.
The National Building Research Organisation issued early warnings for several areas following persistent rain across the country.
Meanwhile, authorities have warned communities near the Mahaweli, Kelani and Kalu Ganga rivers to remain alert as water levels continue to rise.
The Central Province education authorities have also allowed school principals to decide whether schools in the Hatton and Nuwara Eliya zones should close because of the prevailing conditions.
Fishing and naval communities have received separate warnings over rough seas, strong winds and waves reaching up to three metres.
Sri Lanka Landslide Warnings Cover Four Districts
The NBRO issued Stage 2 landslide warnings, classified as “Be Alert,” for several Divisional Secretariat divisions.
The affected areas include Pasbage Korale and Ganga Ihala Korale in the Kandy District.
The warning also covers Yatiyantota in the Kegalle District and Ambagamuwa and Norwood in the Nuwara Eliya District.
In addition, the organisation issued Stage 1 pre-warnings, classified as “Be Vigilant,” for several areas in the Kegalle, Nuwara Eliya and Ratnapura districts.
Residents in vulnerable locations should monitor changes in the surrounding environment and follow instructions from disaster-management authorities.
Signs such as cracks in the ground, leaning trees, unusual water seepage or movement in slopes may indicate growing danger.
Meanwhile, the Provincial Education Director has delegated decisions on school closures in Hatton and Nuwara Eliya to individual principals.
Principals must assess local weather, transport conditions and possible risks before deciding whether schools should remain open.
The measure allows school administrators to respond quickly when conditions vary between different locations.
Mahaweli, Kelani and Kalu Ganga Levels Rise
The Irrigation Department said rainfall during the past 24 hours caused water levels to rise rapidly in the upper catchments of several major rivers.
Rainfall exceeding 200 millimetres was recorded in upper Mahaweli areas, including Nawalapitiya, Nanu Oya and Wattewala.
Authorities advised residents living near the Mahaweli River between Nawalapitiya and Peradeniya to remain vigilant.
Continuous rain could increase water levels further and affect low-lying communities along the river.
The upper Kelani River catchment also received significant rainfall.
Areas including Laxapana, Norwood and Kitulgala recorded between 100 and 150 millimetres of rain.
As a result, low-lying areas between Kitulgala, Avissawella and Hanwella face a possible inundation risk.
Residents should follow official river-level updates and prepare to move important belongings if conditions worsen.
The Kalu Ganga also rose towards dangerous levels following approximately 100 millimetres of rainfall in upper catchment areas around Ratnapura.
However, the Irrigation Department’s Hydrology and Disaster Management Division said no major flood threat had developed in several other river basins.
These include the Nilwala Ganga, Gin Ganga, Maha Oya and Attanagalu Oya basins.
Nevertheless, weather conditions can change quickly. Communities near waterways should therefore continue monitoring official warnings.
Strong Winds Could Damage Buildings and Power Lines
The Meteorological Department forecast further heavy rainfall during the next 36 hours.
The Sabaragamuwa Province and the Kandy and Nuwara Eliya districts could receive rainfall of up to 50 millimetres.
Strong winds of between 40 and 50 kilometres per hour may also affect several regions.
These include the North-Central, Sabaragamuwa, Southern, Central and North-Western provinces, as well as the Trincomalee area.
The Natural Disaster Early Warning Centre warned that strong winds could damage roofs and other vulnerable structures.
Electricity and communication lines may also face disruption.
Agricultural land, crops and coastal infrastructure could suffer damage if wind conditions intensify.
Residents should secure loose roofing materials, outdoor equipment and objects that could become dangerous during sudden gusts.
People should also avoid standing close to trees, unstable structures and exposed power lines.
Rough Seas Threaten Fishing and Naval Operations
Sea conditions are expected to remain dangerous along a large stretch of Sri Lanka’s coastline.
Wind speeds over waters extending from Puttalam through Colombo, Galle and Hambantota to Pottuvil could reach between 50 and 60 kilometres per hour.
Waves may rise to between 2.5 and three metres.
These conditions could make the sea rough and hazardous for small vessels.
Fishing and naval communities have therefore been advised to exercise extreme caution before beginning maritime operations.
Operators should closely follow forecasts and warnings issued by the Meteorological Department and other authorities.
The combination of intense rainfall, rising rivers, unstable slopes and strong winds creates several overlapping dangers.
People in affected areas should avoid unnecessary travel and follow evacuation instructions where authorities issue them.
The latest Sri Lanka landslide warnings underline the need for continued vigilance, particularly in hill-country communities and low-lying areas near major rivers.
