The Meteorology Department yesterday (31) said showers or thundershowers could occur over most parts of the country beginning from today (1) in the evening or night.
Meteorologist Preethika Jayakody said cloudy skies will prevail over the Southern half of the island.
She said heavy showers above 150 millimetres can be expected at some places in the Western, Southern, Sabaragamuwa, Central, and Uva provinces. Heavy showers above 100 millimetres could occur at some places elsewhere.
Jayakody also cautioned of possible strong winds and lightning strikes, advising precautionary measures to minimise damage caused by temporary localised strong winds and lightning strikes.
Along with the southward movement of sun, it is going to be directly over the latitude of Sri Lanka from 28 August to 7 September. The sun is expected to be directly overhead Kappachchi in Vavuniya District and Thammannekulama in the Anuradhapura District today around 12:10 p.m.
Meanwhile, Jayakody said showers or thundershowers can be expected in most parts of shallow and deep seas today.
Wind speed is expected to be from 20 to 30 kmph in the seas surrounding the island of Sri Lanka and expected to be increased to 45 to 55 kmph at times in the seas off the coast from Galle extending to Pottuvil via Matara and Hambantota. The aforesaid seas are expected to be turbulent at times while other seas surrounding the island would remain moderate, Jayakody added.
Meanwhile, Assistant Director Media and Public Relations of Disaster Management Centre (DMC), Janaka Handunpathiraja said along with the prevailing inclement weather conditions, people residing in landslide prone areas have been asked to be vigilant and in case they find any landslide warning signs to inform the DMC immediately.
He said people living near river basins and low-lying areas have been asked to be vigilant to protect life and property.
The public have been asked to refrain from gathering near or visiting paddy fields, tea plantations, bunds, and water fields and reservoirs, instructing them to take shelter in safe places and to refrain from using high voltage electric and electronic items and to keep them away, unplugging from power grid, and travelling in open vehicles like bicycles, boats, and tractors.
Relevant officials have been instructed to take necessary action to minimise the damage caused by the collapse of high-tension line as a result of tree falling or breaking of huge tree branches. The public have been asked to provide information to the DMC over the hotline number 117, Handunpathiraja added.
Meanwhile, Irrigation Director, Eng. S.P.C. Sugeeswara said significant rainfall had occurred in the catchment areas of Kalu Ganga Basin as of 3:00 p.m. yesterday. Analysing the current rainfall situation and water level of river at hydrological stations in Kalu Ganga, there is a possibility of possible flood situation in low lying areas of Kalu Ganga valley situated in Pelmadulla, Nivithigala, Ratnapura, Kuruvita, Ayagama, and Elapatha Divisional Secretariat Divisions.
The public have been asked to pay much attention on this and the residents in these areas and motorists travelling via these regions have asked to be very vigilant, as there is a possibility for water levels to surge in the river at any moment, Eng. Sugeeswara added.
