Torrential rain has overwhelmed drainage systems across Bangkok after days of heavy downpours. Recent flooding in Thailand has affected more than half a million people nationwide, especially in central and eastern Thailand. At least eight people were reportedly killed in the past 10 days. Bangkok authorities are draining water from major canals. A disaster has been declared across all the city, giving local organisations special powers to act. Thousands are seeking refuge in temporary shelters. The governor says a key challenge is getting food to residents and caring for bedridden patients. Overall rainfall across Thailand is expected to ease tomorrow (Monday), but forecasters warn thunderstorms may persist in Bangkok and surrounding provinces.
