The Department of Meteorology says an increase in rainfall could be expected between September and December this year due to the El Nino condition.

Director of the Department of Meteorology R.S. Jayasekara said the variations in the temperature of the surface of the tropical eastern Pacific Ocean could cause the El Nino oscillation, noting that all provinces in the island except for the Northern Province will experience heavy showers as a result.

He however noted that rainfall over the country next year would reduce, following the increase this year.

Sri Lanka was last affected by El Nino oscillations in 1997. Jayasekara said the phenomenon would directly affect the area bordering Indonesia.

Meanwhile, the Met. Department says that the possibility for increasing Southwest monsoonal wind speeds over the country, particularly along the western slopes of the central hills and suburban sea areas, is still high.

However, the prevailing showery weather in the Southwestern part is expected to reduce on Wednesday.
