Submerged roads in Thailand's capital have paralyzed transportation and forced officials to issue red alerts in the worst hit areas. Thai authorities declared a formal flood disaster on September 26 as torrential rains left many of the city's primary streets underwater and triggered citywide congestion.

The emergency state follows a 48 hour period of persistent heavy downpours that caused widespread flooding throughout Bangkok. Emergency crews are operating in the most affected districts as the city manages the aftermath of the deluge.
