Heavy rain pounded Bang Lamung district early on Tuesday, causing flooding on roads and in communities, and the runoff eroded sections of Pattaya beach.
The downpour began around 12.20am and lasted more than an hour. The floodwater was 50-80 centimetres deep in some areas.
A section of road along the railway and parts of Sukhumvit Road were flooded and impassable to small vehicles and motorcycles. The water gradually receded.
Pattaya beach was eroded between Pattaya Nua and Pattaya Klang. The huge volume of runoff swept away sand that the Marine Department had brought in to expand the Pattaya shoreline and restore its attractiveness to visitors.
The erosion on the beach was about a metre deep and 4 metres wide in several spots. Rubbish was also deposited along the shore.
