BANGKOK – The Thai Meteorological Department (TMD) has warned of isolated heavy to very heavy rain across upper Thailand from Sept 4 to Sept 7, raising the risk of flash floods and run-off.
The advisory, issued at 5am on Sept 2, warned that northern and north-eastern Thailand are expected to experience the heaviest rainfall.
The department attributed the conditions to a monsoon trough extending across the north and upper north-east, combined with a moderate south-west monsoon prevailing over the Andaman Sea, Thailand and the Gulf of Thailand.
The advisory did not identify individual provinces, specifying only the north and north-east as the areas of greatest concern.
Flash-flood precautions
TMD warned that heavy and accumulated rainfall could cause flash floods, rapid run-off and short-term inundation.
Residents and travellers were advised to:
Monitor conditions in foothill areas near waterways and in low-lying locations
Avoid routes repeatedly affected by flooding
Exercise particular caution in low-lying areas where water may accumulate quickly
Plan daily activities and journeys carefully during the warning period
Follow subsequent TMD announcements
