The Royal Irrigation Department is monitoring the 'summer storms' from 11 to 13 March, with machinery and personnel prepared to respond to thunderstorms.
On 10 March 2026, the Royal Irrigation Department's Smart Water Operation Center (SWOC) reported that, according to the Meteorological Department's warning, summer storms will affect upper Thailand from 11 to 13 March 2026. The northern region will be impacted first, followed by the central region, western parts of the northeast, the east, and including Bangkok and its vicinity. The storms are expected to bring thunderstorms, strong gusty winds, hail in some areas, heavy rain in certain locations, and possible lightning in some spots.
These conditions are caused by westerly wind currents moving in from Myanmar covering the north, combined with a moderate cold air mass from China spreading over the northeast, east, and the South China Sea. Meanwhile, upper Thailand experiences hot weather, leading to these unstable weather conditions.
Meanwhile, the Royal Irrigation Department is closely monitoring and assessing water situation trends, instructing irrigation projects nationwide to prepare for sudden increases in rainfall by managing water levels in reservoirs and other water sources appropriately. They are also inspecting the stability of irrigation structures, drainage systems, and areas prone to flooding comprehensively.
In addition, continuous removal of water hyacinths and aquatic weeds in water sources is being carried out to improve drainage efficiency, reduce waterway blockages, and accommodate possible increased rainfall during this period. These are proactive measures in water management preparedness.
At the same time, machinery, water pumps, water pushers, and staff have been readied to deploy immediately in case of flash floods, sudden flooding, or waterlogging, aiming to minimize impacts on the public as much as possible.
