Reader Briefing

Assoc. Prof. Dr. Seri Suparatit warns that the convergence of four environmental factors could lead to a catastrophic flooding situation in Bangkok and surrounding areas.

•Assoc. Prof. Dr. Seri Suparatit held a press conference on October 2, 2026, regarding preparations for northern runoff in Bangkok and its vicinity.
•Runoff volume in 2026 is estimated to be nearly 66% lower than the 2011 great flood, with an expected inundation period of about 1 month.
•A 'Worst Case Scenario' occurs if the water flow rate increases to 3,000 cubic meters per second.
•The L-Alert system is proposed to empower local government organizations to be the center of disaster warnings for citizens.

Overview

•On October 2, 2026, at 13:30, the Climate and Disaster Center of Rangsit University and the National Disaster Warning Council Foundation held a press conference.
•Assoc. Prof. Dr. Seri Suparatit stated that water may stay for about 1 month in 2026, but could last longer without accelerated drainage from low-lying areas.
•Pushing water mass toward the east and west will affect peripheral areas, specifically Thung Rangsit, Khlong Raphi Phat, and Khlong 6 Wa Sai Lang.
•Assoc. Prof. Dr. Seri Suparatit warned that the simultaneous occurrence of current drainage water, additional rainfall, northern runoff, and high sea levels would be a "catastrophe".
•The current water flow rate is approximately 2,600 cubic meters per second, which could rise to 3,000 cubic meters per second if 400 cubic meters per second is added from the Yom River or rainfall.
•The drainage of water masses primarily relies on the pumping capacity of the Bangkok Metropolitan Administration.
•Local government organizations, including PAOs, municipalities, TAOs, Kamnans, and village headmen, should use the L-Alert system to notify citizens via various channels.
