The user wants a short summary of the Thai weather warning article in English. The article is from the Thai Meteorological Department (TMD) warning No. 9 about heavy to very heavy rain from Oct 21-25, 2026 (2569 BE). It affects 15 provinces
At 5:00 AM on October 21, 2026, the Thai Meteorological Department announced Warning No. 9 for heavy to very heavy rain across Thailand, effective until October 25. From October 21-25, the southern region will experience continuous rain with heavy to very heavy downpours in some areas. The lower northeastern, lower central, Bangkok metropolitan, eastern, and upper southern regions will see increased rainfall with strong gusty winds in places. Residents in these areas are warned of dangers from strong winds, heavy rain, and accumulated rainfall that could trigger flash floods and mudslides in foothill and low-lying areas. This is caused by a monsoon trough passing through the central south combined with the southwest monsoon covering the lower Andaman Sea, while a high-pressure system from China extends over upper northern, upper northeastern Thailand, and the South China Sea. In the Andaman Sea and Gulf of Thailand, waves will exceed 3 meters in thundery areas; mariners should navigate with caution and avoid thundery zones. For safety, the public is urged to plan travel carefully and monitor updates via the TMD website or hotlines. The 24-hour forecast shows the south with continuous rain and heavy downpours, while upper Thailand faces scattered thundershowers and strong gusts. Regional forecasts detail specific provinces affected, temperatures, and wind conditions.
