Chilly weather: Thailand braces for deluge, winter season nears
Cool mornings, strong winds, and flash flood warnings issued
Thailand is on high alert as a severe tropical storm brews offshore, while a high-pressure system from China brings cooler air and strong winds to the upper regions.
The Thai Meteorological Department (TMD) reports that a moderate high-pressure system is affecting northern and northeastern Thailand. Morning temperatures are cooler, with strong winds and a slight temperature drop expected.
The weather forecast for 6am today, October 22, to 6am tomorrow, October 23, is as follows:
The northern regions will see isolated showers, with lows between 20 and 23°C and highs of 32 to 35°C. Winds will reach up to 15 km/h.
In the northeast, places such as Mukdahan, Amnat Charoen, and Ubon Ratchathani may experience isolated thundershowers. Temperatures will range from 19 to 24°C, with highs between 31 and 33°C. Winds will blow at 15 to 30 km/h.
The central region will see isolated light rain, with temperatures ranging from 24 to 25°C in the morning and climbing to 32 to 34°C later in the day. Winds will stay light, between 10 and 20 km/h.
Eastern provinces, including Sa Kaeo, Chanthaburi and Trat, can expect thundershowers. Morning temperatures will be 23 to 26°C, rising to 32 to 35°C. Northeasterly winds will blow at 15 to 30 km/h. Waves are expected to reach 1 metre and over 2 metres during storms.
In the south, a monsoon trough and easterly winds are expected to cause fairly widespread thundershowers and isolated heavy rain. Eastern coastal provinces from Prachuap Khiri Khan to Narathiwat are likely to be the hardest hit, with flash floods possible. Temperatures will range from 23 to 26°C, with highs between 32 and 34°C. Winds are expected at 15 to 30 km/h, with sea levels above 2 metres during thundershowers.
The western coast, including Phuket and Krabi, will also face heavy showers. Temperatures will dip to 23 to 24°C, with daytime highs between 30 and 33°C. Westerly winds will reach 30 km/h, with wave heights over 2 metres in stormy areas, according to the TMD.
In Bangkok, residents can expect isolated light rain with temperatures from 24 to 25°C in the morning and highs up to 35°C. Winds remain light.
Severe tropical storm Fengshen, currently over the South China Sea, is expected to make landfall in Vietnam but will not enter Thailand. However, residents are advised to take precautions against flash floods and avoid flood-prone areas. All boats are urged to navigate with caution.
Thailand will officially enter the winter season tomorrow, October 23, about a week later than usual, according to the TMD. Cooler temperatures will first appear in the north and northeast, gradually spreading to the central and eastern regions. Southern Thailand, however, will continue to experience frequent rain and isolated heavy to very heavy showers, according to The Nation.
The transition marks a shift in prevailing winds to the northeast and east, with rainfall dropping significantly in the upper regions. Suchada Thaensap, Secretary to the Minister of Digital Economy and Society, said that not all areas will feel the cold immediately. The chilliest period is expected between mid-December and early February, with average minimum temperatures of around 21 to 22°C.
In mountainous areas such as Mae Hong Son, Chiang Rai, Nan, and Loei, temperatures could fall to 7 to 8°C, with frost likely. In Bangkok and surrounding provinces, minimum temperatures are forecast at 18 to 20°C.
Meanwhile, the south remains under threat from heavy rain triggered by low-pressure systems and tropical cyclones. These conditions may lead to flash floods, strong winds, and thunderstorms, particularly along the Gulf coast. Residents are advised to stay alert and avoid flood-prone areas.
