The Natural Hazards Early Warning Centre has issued a critical heavy rain advisory for multiple provinces and districts across Sri Lanka, effective from 12:00 noon on February 21, 2026, until 8:30 a.m. on February 22, 2026. The alert covers the Central, Uva, and Sabaragamuwa provinces, along with the Ampara, Batticaloa, and Polonnaruwa districts, where heavy rainfall exceeding 100mm is anticipated.
Weather System Behind the Alert
The heavy rainfall warning stems from a low-level atmospheric disturbance currently positioned in the vicinity of Sri Lanka. This meteorological phenomenon is expected to bring significant precipitation to the affected regions, with rainfall amounts potentially exceeding 100 millimeters in some locations. Such atmospheric disturbances are common in the region and can rapidly intensify, leading to dangerous weather conditions.
The timing of this weather system coincides with seasonal patterns that often affect the island nation, making it crucial for residents and authorities to remain vigilant. The Natural Hazards Early Warning Centre continues to monitor the situation closely, providing updates as the weather system evolves.
Affected Areas and Expected Impact
The advisory specifically targets three major provinces: Central, Uva, and Sabaragamuwa, which encompass significant population centers and agricultural regions. Additionally, three districts in the Eastern and North Central provinces - Ampara, Batticaloa, and Polonnaruwa - are included in the warning zone.
These areas are particularly vulnerable to heavy rainfall due to their topographical features and drainage systems. The Central Province, with its mountainous terrain, faces risks of landslides and flash floods, while the flatter regions in the Eastern Province may experience widespread flooding and waterlogging.
Agricultural activities in these regions could face significant disruption, as heavy rains can damage crops, affect harvesting operations, and impact livestock. The timing is particularly concerning for farmers who may have crops ready for harvest or recently planted fields that could suffer from waterlogging.
Safety Precautions and Recommendations
Residents in the affected areas should take immediate precautions to ensure their safety and minimize property damage. It is advisable to avoid unnecessary travel during the heavy rain period, particularly in areas prone to flooding or landslides. Those living in low-lying areas should be prepared for potential evacuation if water levels rise rapidly.
Motorists should exercise extreme caution when driving, as heavy rainfall can reduce visibility and create hazardous road conditions. Flooded roads pose significant risks, and drivers should never attempt to navigate through standing water, as it can be deeper than it appears and hide dangerous obstacles.
Homeowners should secure loose outdoor items that could become projectiles in strong winds often associated with heavy rain systems. Clearing drainage systems around properties can help prevent localized flooding, and having emergency supplies readily available is always prudent during severe weather events.
Emergency Preparedness Measures
Local authorities and emergency services in the affected provinces and districts should be on high alert during the advisory period. Emergency response teams should be positioned strategically to respond quickly to any incidents related to flooding, landslides, or other weather-related emergencies.
Communication systems should be tested and backup power sources prepared, as heavy rains can sometimes disrupt electrical services. Evacuation routes should be reviewed and kept clear, ensuring that emergency vehicles can access affected areas if needed.
Schools and educational institutions in the affected areas may need to consider temporary closures if conditions become severe. Parents should stay informed about school policies regarding weather-related closures and have alternative arrangements for their children if necessary.
Monitoring and Updates
The Natural Hazards Early Warning Centre will continue to monitor the atmospheric disturbance and provide updates as conditions change. Citizens are encouraged to stay tuned to official weather bulletins and advisories through reliable news sources and government communications.
Weather conditions can change rapidly, and what begins as moderate rainfall can quickly intensify into dangerous conditions. The 20.5-hour duration of this advisory reflects the extended nature of the expected weather system, requiring sustained vigilance from both authorities and residents.
As Sri Lanka frequently experiences monsoon-related weather patterns, this advisory serves as a reminder of the importance of weather preparedness and the effectiveness of early warning systems in protecting lives and property. The coordinated response between meteorological services and emergency management agencies demonstrates the country's commitment to public safety during severe weather events.
Residents should remain alert throughout the advisory period and report any weather-related emergencies to appropriate authorities immediately. By taking proper precautions and staying informed, communities can minimize the impact of this heavy rainfall event.
