Sri Lanka's Department of Meteorology forecasts gradual improvement in southwestern rainfall after August 15, though El Niño conditions may continue affecting dry regions through the Northeast Monsoon season.

The Department of Meteorology has indicated that heavy rainfall currently affecting Sri Lanka's southwestern regions should begin to diminish following August 15, according to meteorologist Srimal Herath. The wet conditions are anticipated to maintain their present intensity over the coming days before the expected relief arrives.

However, Herath cautioned that El Niño conditions currently influencing weather patterns across the island may extend into the Northeast Monsoon season next year. These conditions are expected to have pronounced effects on areas already experiencing dry weather, potentially intensifying drought-like circumstances in vulnerable regions.

Additionally, the meteorologist noted that declining wind speeds combined with elevated humidity levels could raise the perceived temperature across the country in the short term. The combination of these factors may result in higher heat indices that residents should be aware of. The Department of Meteorology indicated it will maintain continuous monitoring of weather conditions throughout Sri Lanka to track these developments and provide updated forecasts as conditions evolve.
