Thunderstorms, Hail Forecast for Upper Thailand; Heavy Rain Expected in South
The Thai Meteorological Department has warned of thunderstorms, strong winds, hail, and isolated heavy rain across upper Thailand for the next 24 hours, urging the public to avoid open areas and unstable structures. A high-pressure system from China is driving the unstable conditions, with waves exceeding two meters in stormy areas of the Andaman Sea and Gulf of Thailand. From November 7 to 13, the southern region will face increased rainfall with heavy to very heavy downpours as easterly winds strengthen.
At 5:00 PM on November 6, 2026, the Thai Meteorological Department issued a 24-hour forecast stating that upper Thailand will continue to experience unstable weather characterized by thunderstorms, strong gusts, hail, and isolated heavy rain. The public is warned of dangers from heavy rain, thunderstorms, and strong winds, and advised to stay away from open fields, large trees, unstable structures, and billboards. This is due to a high-pressure area or cold air mass from China covering upper Thailand and the South China Sea, causing easterly winds to prevail over the Gulf of Thailand, Thailand, and the Andaman Sea. For the Andaman Sea and Gulf of Thailand, areas with thunderstorms will have waves higher than two meters; boaters should proceed with caution and avoid sailing in thundery areas. Additionally, from November 7 to 13, the southern region will see increased rainfall with heavy rain in many areas and very heavy rain in some places, as easterly winds over the Gulf, South, and Andaman strengthen.
