Thailand’s record floods have encroached deeper into the capital, swamping a major intersection in the northern edge of the city center and threatening the subway system. Three stations in Bangkok’s subway system are being closely monitored but are still open. Steel barriers have been put around the underground stations in recent weeks to protect against possible inundation. The Thai Prime Minister called on Bangkok residents to stay calm. Yingluck Shinawatra, Thai Prime Minister, said, \"Water from the north is now starting to recede and we’re trying to drain floodwaters into canals. But we have to monitor some floodgates to control the water flow into Bangkok.\"
