The prevailing showery weather condition over the island, particularly in the southwestern region, is expected to persist in the last two weeks of this month, Meteorology Department Duty Meteorologist Shanika Dissanayake told the Daily News.

The Duty Meteorologist said they expect thundershowers on these days since the country is now experiencing the latter part of southwest monsoonal rains.

“The situation would change with the arrival of the second inter-monsoon period. The second inter-monsoon period is generally expected to begin around early October,” she said.

She said showers or thundershowers will occur in the Western, Sabaragamuwa, Southern, Central and North Western Provinces. Fairly heavy rainfall of about 100 mm is likely to prevail in some places in the Central and Sabaragamuwa Provinces and in the Galle and Matara districts. Showers or thundershowers will occur in several places elsewhere after 2.00 pm. Showers may occur in the Jaffna and Mannar districts during the morning too.

The Naval and fishing communities are requested to be vigilant since temporary gusty winds (up to 70–80 kmph) and rough seas can be expected during thundershowers. The sea area extending from Hambantota to Pottuvil and the sea area extending from Puttalam to Mullaitivu via Mannar and Kankasanturai can be rough at times as the wind speed can increase up to 50–55 kmph.

According to the islandwide water level situation in major rivers issued by the Disaster Management Centre, the water levels of the Kalu and Nilwala rivers have risen as a result of persistent rains and residents living in close vicinity to the aforementioned rivers are advised to be vigilant of the situation.

The National Building Research Organization (NBRO) on Sunday (16) issued landslide warnings for Ratnapura, Nuwara Eliya, Kegalle and Kalutara districts and people living in landslide susceptible areas are advised to be extra vigilant and should be ready to move quickly to safe places if heavy rain continues.

During this landslide early warning period, the NBRO advised that people pay attention to the pre-landslide signs such as the development of cracks on the ground, deepened cracks and ground subsidence, slanting of trees, electrical posts, fences and telephone posts, cracks in the floors and walls of buildings which are built at slopes, sudden appearance of springs, emerging muddy water, blockage or disappearance of existing springs.
