North, Northeast forecast is for heavy rain, flood risk

Visitors and residents are warned to exercise caution near the 850-metre-long Uttamanusorn Bridge, better known as Saphan Mon, in Kanchanaburi's Sangkhla Buri district as continuous heavy rain has caused water levels in the Song Kalia River to rise rapidly. Strong currents and floating debris have been reported near the country's longest wooden bridge. (Photo: Piyarach Chongcharoen)

Heavy to very heavy rain is expected across parts of northern and northeastern Thailand from Tuesday into Friday, raising the risk of flash floods and forest runoff in vulnerable areas.

In its second weather warning issued on Sunday, the Meteorological Department said that a monsoon trough over the North and upper Northeast, coupled with a fairly strong south-westerly monsoon over the Andaman Sea and the Gulf of Thailand, would drive the wet conditions.
