Thailand is closely monitoring flood risks in 12 provinces, including Chiang Mai, as continued heavy rain raises the risk of flash floods, forest runoff and overflowing waterways, particularly in the north and northeast. Thailand continues to experience heavy rain in some areas as a monsoon trough passes across the upper north and northern Laos. The conditions could bring heavy to very heavy rain and accumulated rainfall, increasing the risk of flash floods, forest runoff and overflowing waterways. The central region is forecast to see thunderstorms across 40% to 60% of the area, with isolated heavy rain. Parts of the upper western coast of the south are also expected to experience heavy rain.
