Thailand Braces for Heavy Rains, Flash Floods in 31 Provinces
Thailand's Meteorological Department warns of heavy to very heavy rains and flash floods across 31 provinces through August 9, with waves reaching 4 meters in the Andaman Sea forcing small boats ashore.

The northern, northeastern, and eastern regions will see increased rainfall with heavy to very heavy conditions in some areas, while the central region, Bangkok, and the southern region will experience heavy rain in scattered locations.
