Hydro storage levels in the Ceylon Electricity Board (CEB) controlled reservoirs hadn’t improved much despite torrential rains that it countrywide, the Systems Control and Generation Department of the Board indicates. Hydro contributes to the system 8.57 GWh or 26.75 per cent.

Castelreagh current level 11.91 current level below spill –percentage 21.08, rainfall 1.0, Maussakelle 14.02, 26.0, 1.0, Kotmale 21.92, 27.0, 0.0, Victoria 27.03, 31.0, 15.00, Randenigala 5.34, 0.0, 71.5, 0.0 and Samanalwewa 19.17, 27.5 and 10.0.

Despite countrywide showers, the CEB maintained reservoirs hadn’t received much rains apart from Castlereagh, a senior engineer said adding Castlereagh igh level had jumped to 30 from 20 per cent.
However, he said that most of the Irrigation Department run reservoirs had reached spill levels.

The low-level atmospheric disturbance persists in the vicinity of Sri Lanka would continue, hence prevailing showery condition is expected to continue.

The Meteorological Department said showers or thundershowers will occur over most parts of the country. Heavy showers above 100mm can be expected at some places in Western, Sabaragamuwa, Central, North-western, Northern, and Northern-central provinces and Galle and Matara districts.

Fairly heavy showers of about 75mm can be expected at some places elsewhere too. The public is  requested to take adequate precautions to minimise damages caused by temporary localized strong winds and lightning during thundershowers. 
Landslide warnings issued for eight districts continue to remain in place due to the heavy rains forecast.

National Building Research Organization (NBRD), Senior Geologist Dr Wasantha Senadheera said that people in Badulla, Colombo, Kalutara, Kandy, Kegalle, Kurunegala, Matale, and Nuwara Eliya districts should be vigilant due to heavy rain.

Meanwhile, the Department of Irrigation further urges the public to be more careful when using reservoirs as the water levels in several reservoirs have also risen. Several sluice gates were opened due to the rising water levels in the Rajanganaya, Angamuwa, Deduru Oya, and Batticaloa Unnachchiya reservoirs due to last week’s heavy rains.

The Department of Irrigation said that the water levels of Deduru Oya and Kala Oya could also rise with the projected weather forecast. Wind speed can increase up to 35-40 kph at times in the sea areas off the coast extending from Galle to Hambantota via Matara due to the low-level atmospheric disturbance in the vicinity of Sri Lanka. The fishing and naval communities are advised to be vigilant in this regard.

Showers or thundershowers will occur at times in the sea areas around the island. Heavy showers can be expected at some places in the sea areas off the coast extending from Kankasanturai to Matara via Mannar, Puttalam and Galle. Winds will be south-westerly or variable in direction and wind speed will be 35-40 kph. Winds’ speed can increase up to 40-50 kph at times in the sea areas off the coast extending from Galle to Hambantota via Matara. The sea areas off the coast extending from Puttalam to Potuvil, via Colombo, Galle, Matara and Hambantota will be rough at times. The other sea areas around the island will be fairly rough. Temporarily strong gusty winds and very rough seas can be expected during thundershowers.
