According to forecasts from the Meteorological Department, from 4 to 7 Oct 2026, upper Thailand will experience thunderstorms, strong gusts, and heavy to very heavy rain in some areas. From 5 to 6 Oct, these conditions will impact the north, central regions including Bangkok and its vicinity, the east, and upper south. Between 8 and 13 Oct, rainfall is expected to increase in the central, eastern, and southern regions. Residents are urged to remain vigilant for flash floods, flash floods from mountain runoff, and waterlogging.

Especially vulnerable are hillside and lowland areas, as well as areas along the Chao Phraya River that may be affected by increased water discharge downstream of dams. People should closely monitor warnings, prepare to move belongings to higher ground, and be ready to evacuate as advised by officials. Avoid walking or driving through fast-flowing water, and do not shelter under large trees or unstable billboards during storms.

Meanwhile, DDPM will deploy personnel and machinery to speed up water pumping, clear routes, and relocate flood victims to safe areas, prioritizing vulnerable groups. They will also deliver food, drinking water, medicine, and essential items to affected households.

In areas where water has receded, damage assessments will be expedited to provide assistance according to criteria, alongside ongoing situation updates and guidance for self-protection to ensure public safety and rapid return to normal life.
