Thailand braces for cold mornings and air pollution alert
The Thai Meteorological Department (TMD) has forecasted that the cool air mass will continue to blanket the region, leading to cold mornings and frost on mountain peaks. The south will experience rain, and there is a warning for increased air pollution.
Today, January 21, the high-pressure system or cool air mass persists over upper Thailand and the South China Sea, causing morning fog and a slight temperature increase. The north, northeast, and central regions will remain cool to cold, while the east, upper south, and Bangkok including its vicinities will experience cool mornings.
Mountain peaks and highlands will be very cold, with frost in some areas. Residents are advised to take care of their health due to the cold weather, be cautious of fire hazards due to dry conditions, and exercise caution when travelling through foggy areas.
The TMD has issued a warning about rising PM 2.5 pollution due to an inversion layer, which can spread air pollutants. The northeast monsoon continues to cover the Gulf of Thailand, the south, and the Andaman Sea, causing 1 to 2 metres waves in the lower Gulf. Mariners in these areas should navigate with caution.
The current weather conditions contribute to the accumulation of dust particles. Air ventilation is currently rated as poor to weak, with the wind over upper Thailand weakening.
Dust particle concentration is expected to remain steady with slight fluctuations.
