Floodboard is an independent, free flood information service designed to help people make safer travel decisions in Bangkok and across Thailand. Its live map brings together flood reports and data from sources including Bangkok’s Drainage Department, the Department of Highways, Traffy Fondue, ThaiWater, sensors, CCTV, news, and social media. Users can check affected roads, reported water depth, estimated flooded stretches, and whether conditions may be passable for motorbikes, sedans, pickups, and trucks.

The service also offers route planning and flood-avoidance guidance, with options to view official and community reports, rainfall, canal levels, road-water sensors, and other relevant map layers. People can submit anonymous, location-based updates about flooding, road passability, water depth, and optional photos. Reports are weighted and assessed for corroboration, while official notices receive greater weight; the site cautions that information may be delayed or inaccurate.

Floodboard also provides free open data and emphasizes that an unmarked road is not necessarily dry
