Severe flooding continues to affect eastern Bangkok. Governor Chadchart Sittipunt said in a live Facebook post on Sunday morning that water had filled the Lat Phrao, Prawet Burirom, Prem Prachakorn and Saen Saep canals, where pumps were experiencing problems. More than 30,000 people were affected in Lat Krabang district, he said, while Ramkhamhaeng and Bang Kapi also faced severe flooding.

About 10 millimetres of rain fell on Sunday morning. Chadchart said flooding remained serious in the capital's eastern districts and officials were trying to speed up drainage. He made the remarks while riding as a passenger on a motorcycle taxi towards City Hall in Din Daeng.
