Heavy rain warning in Thailand as temperatures drop
The Thai Meteorological Department (TMD) has issued its 8th weather warning for heavy rain, identifying key provinces that will be most affected. Temperatures will drop by 1 to 2 degrees Celsius (°C) across many regions.
A moderate high-pressure system persists over upper Thailand and the South China Sea, causing cooler temperatures in the northern, northeastern, and central areas of Thailand. These regions will experience cold to very cold weather, particularly in mountainous areas where frost is expected. Meanwhile, the east and upper south regions, including Bangkok and its vicinity, will see cool mornings. Residents are advised to dress warmly and be cautious of potential fire hazards due to dry conditions.
The northeast monsoon over the lower Gulf of Thailand and southern region remains strong, leading to heavy rain in parts of the lower south. The Gulf of Thailand’s lower section will experience strong winds with waves reaching 2 to 3 metres, exceeding 3 metres in stormy areas. The upper Gulf of Thailand and the Andaman Sea will see waves around 2 metres, with higher surges during storms. Residents in the eastern southern region should be on alert for heavy rain and coastal waves. Seafarers are urged to navigate carefully and avoid sailing in stormy conditions. Small boats in the lower Gulf should stay ashore until today, January 18.
Current weather conditions could increase dust accumulation due to moderate air circulation and weakening winds in some areas of upper Thailand.
