The Bangkok Governor has declared all 50 districts disaster zones after heavy rain caused flooding and traffic problems, with eastern Bangkok hardest hit. Canal levels are critical and expected to rise, and the Chao Phraya Dam discharge is being raised to 1,950 cu m/sec. Flooding has been reported in 20 provinces, and heavy rain is forecast nationwide until Sunday. For a Bangkok shop or workshop, expect delivery delays and road closures, move stock and equipment off the floor, and check whether your staff can get to work safely.
