It stated that upper Thailand still experiences unstable weather characterized by thunderstorms, strong gusts, and localized heavy rain. The public is advised to be cautious of dangers from thunderstorms and strong winds and to avoid staying in open areas, under large trees, and near unstable billboards.
From 7 to 9 November 2026, the southern region will see increased rain with heavy showers in many areas and very heavy rain in some places. People should be cautious of accumulated rainfall that could cause flash floods and flash floods, especially in foothill areas near waterways and low-lying zones.
This is due to a high-pressure area or another cold air mass from China spreading over upper Thailand and the South China Sea, causing stronger easterly winds over Thailand and the Gulf of Thailand.
