The Meteorological Department (TMD) issued a weather warning predicting severe storms in 12 provinces, with heavy rain expected to cover 70% of the area. This could lead to flash floods and severe weather conditions, with temperatures dropping.
The northeast monsoon, which is currently quite strong, is affecting the Gulf of Thailand and the southern region. A low-pressure system also covers the lower southern region and Malaysia, resulting in heavy rain in some areas.
The TMD also issued a notice regarding a cold air mass from China, which is spreading over upper Thailand and the South China Sea. This phenomenon is causing cooler temperatures, strong winds, and a further drop in temperatures.
Dust and haze levels in upper Thailand are expected to decrease due to stronger winds and the current rainfall. The weather forecast for the next 24 hours reports cool to cold weather with strong winds in the northern region.
Patchy light rain is expected in the northernmost areas, with minimum temperatures ranging from 15 to 20 degrees Celsius (°C) and maximum temperatures between 25 to 30°C. Mountain peaks will be cold to very cold, with minimum temperatures between 6 and 12°C. Northeasterly winds will blow at speeds of 10 to 15 kilometres per hour (km/h).
