Wisesight tracked 167,607 flood-related posts from 16–26 September 2026 in Bangkok and central Thailand, generating about 40 million engagements. Facebook carried most of the volume; TikTok had far fewer posts but about 14 million engagements. The most-shared official warning channels were the Department of Disaster Prevention hotline 1784, 1555 and Traffy Fondue. For your business, the practical point is to check flood-warning sources early (Meteorological Department alerts, pages that relay them) and to keep emergency contacts and a stock-and-staff plan ready for low-lying areas. The report itself contains no new policy, cost or deadline.
