Floodwaters have reached the northern edge of central Bangkok and are threatening the Thailand capital’s subway system.

The water that has been creeping through northern Bangkok for more than week flooded Lad Phrao intersection on Friday. The area is home to office towers, condominiums and a major shopping mall and is not far from the famed Chatuchak Weekend Market.

Local media reported the water depth at 15 inches (40 centimetres).

Officials from Bangkok’s subway system say they are closely monitoring three stations in the area, though all remain open.

The government has asked residents to evacuate eight of the city’s 50 districts because of the flooding. It has killed more than 400 people in Thailand since late July.
