Heavy rains with up to 100 mm are likely in some places. Kegalle and Galle saw accumulations of 219 mm and 160 mm respectively between 8 am Sunday and 8 am today. Landslide warnings have been issued for Colombo, Gampaha, Kalutara, Galle, Ratnapura and Kegalle.

Colombo (Asia News) – Various parts of Sri Lanka have experienced flooding following heavy rains. Landslide warnings have been issued for Colombo, Gampaha, Kalutara, Galle, Ratnapura and Kegalle.

Level 1 and 2 landslide notices have been issued for Galle, Ratnapura and Kegalle. In the Southern Province, 862 families have been affected.

Heavy rainfall of about 100 mm are likely in some places with top accumulations between 8 am Sunday and 8 am today in Kegalle (219 mm) and Galle (160 mm).

According to Divisional Secretary Himali Rathnaweera, bad weather and torrential rains affected 3,375 people in Kadawathsathara, Galle Divisional Secretariat.

"In this area about 14 houses were partially damaged from lightning and landslides. There could be more reports on damage to houses,” she said.

Heavy rain started again in Colombo, Gampaha, Galle, Ratnapura and Kegalle this morning, causing flooding in some areas.

According to the Meteorology Department, rain will continue in the Western, Central, Southern and Sabaragamuwa provinces for the next 12 hours with 100 mm in some places.

In the south, showers or thundershowers are expected above sea areas because of active cloudiness in the sea. Heavy showers, thundershowers and sudden roughness, associated with a sudden increase in wind speed (up to 70-80 kmph) are highly likely.

Sailors and fishermen have been warned that the sea from Puttalam to Hambantota, especially from Colombo to Galle, could be rough due of wind speeds of up to 50-60 km per hour.

This evening, the National Building Research Organization (NABRO) issued an urgent landslide warning for parts of Colombo, Galle, Kalutara, Kegalle and Ratnapura after rainfall exceeded 100 mm in the last 24 hours.

If this continues, people in the designated areas can expect landslides, slope failures, rock falls, as well as ground subsistence, and should be ready to evacuate to safe places in case of need.

The Meteorology Department warned that, “due to the low-level atmospheric disturbances in the vicinity of Sri Lanka, the prevailing showery condition in Western, Sabaragamuwa, Central, Southern and Uva Provinces is expected to continue during the next 24 hours.”

“Very heavy rainfalls above 150 mm are likely at some places. Fairly Strong winds (40-50kmph) gusting up to (70-80) Kmph can be expected during showers/thundershowers.”
