The National Water Command Centre has issued a warning for some provinces in all regions to brace for flash floods from May 27-June 1.
The NWCC said on Tuesday the southwesterly monsoon over Thailand is gaining strength while a low pressure system is moving from the middle of Vietnam to cover Laos and Cambodia.
