Tropical Storm Dianmu caused floods across 30 of Thailand's northern and central provinces. Six deaths have been reported and an estimated 70,000 homes have been flooded.

Some areas had recently experienced flooding earlier in the month following heavy rain.

There are concerns the flooding will grow worse as the Chao Praya River water level is rising following dam releases upstream. Flood prevention methods are being taken to try to protect against further floods.

Pleiades imagery acquired through the Charter demonstrates the extent of the flooding:
