BMA says about 329,000 households (roughly 700,000 people) across Bangkok have been affected by flooding, worst in Lat Krabang, Bang Kapi and Khan Na Yao. Water is expected to drop as canal levels fall, after which roads and communities will drain in sequence. If your shop or workplace is in these districts, expect disrupted access, staff absences and delivery delays for now. BMA is asking for emergency supplies (water, ready meals, high-clearance trucks, small boats, field kitchens) via 0-2248-5115 or 1555, and is preparing relief and compensation procedures that it has not yet published.
