The Thai Meteorological Department forecasts heavy rain across most regions on 6 Aug (2026), covering 60-70% of the north, northeast, east and western south, due to a monsoon trough. Flash floods and mountain runoff are possible near streams and low-lying areas. Upper Andaman and upper Gulf waves reach 2-4 m, and small boats there should stay in port. Storm Kujira is staying over the South China Sea and is not expected to enter Thailand. For shops, farms and delivery, plan for disrupted travel and stock deliveries, and move outdoor stock and equipment out of low-lying spots.
