The government’s disaster management center said 18 of the reported deaths occurred in the mountainous tea-growing regions of Badulla and Nuwara Eliya in the country’s Central Province, about 300 kilometers (186 miles) east of the capital Colombo, the Associated Press reported.
Another 14 people were missing after another landslide occurred in the same area on Thursday, the center said.
The death toll has risen to 31 since last week, when Sri Lanka began experiencing severe weather. Heavy rains over the weekend flooded homes, fields and roads, causing extensive damage.
Many reservoirs and rivers have flooded and roads have been closed. Officials said some major roads connecting the states were closed.
Authorities stopped trains in some parts of the mountainous region as stones, mud and trees fell onto the tracks, and local television showed workers busy clearing debris. Floodwaters submerged railway lines in some areas.
Local television showed a naval vehicle transporting residents and a car washed away by floodwaters near the eastern town of Ampara, about 412 kilometers (256 miles) east of Colombo.
According to the center, about 4,000 households were affected by the bad weather.
