Heavy rain warning for 46 provinces, North hit hardest
The Thai Meteorological Department (TMD) issued a warning for heavy rain in 46 provinces today, with the northern region expected to be hit the hardest, affecting 80% of the area. Residents are advised to be cautious of potential floods and flash floods.
The TMD forecasts weather conditions for the next 24 hours, predicting a moderate monsoon trough passing over the upper north and upper Laos, extending into a low-pressure area in upper Vietnam.
Combined with the southwesterly and southeasterly winds covering the east and upper Gulf of Thailand, this will cause heavy rainfall in parts of the north, northeast, Bangkok and its vicinity, and the south. The east is expected to experience the heaviest rainfall, the department advised.
“Residents in these areas should be aware of the dangers of heavy to very heavy rainfall, which may cause sudden floods and flash floods, especially in foothill areas and low-lying regions.”
In addition to the rain, moderate wind waves of 1 to 2 metres are expected in the upper Andaman Sea and upper Gulf of Thailand, with waves exceeding 2 metres in thundershower areas. Mariners in the affected regions are urged to proceed with caution and avoid sailing in stormy areas.
