Floodwater in Bangkok has crossed the Lat Phrao intersection on the northern edge of the city center and is closing in on bus terminals, subway stations and Skytrain stations on Sunday, according to reports.

The flood is threatening to disrupt the operation of the Mor Chit bus terminal, the gateway to northern and northeastern Thailand. Stations of the Bangkok Metro and BTS Skytrain are also near the terminal.

Floodwaters have reached the first step of the entrance to the subway stations in Ratchadapisek and Phaholyothin prompting the Mass Rapid Transit Authority (MRTA) to closely watch the situation. There are 18 subway stations and all remain in service, the MRTA said, according to Xinhua.

The subway stations are protected against two-meter high floods.

Below the Mor Chit Skytrain station, the two-lane road was flooded since Saturday. But the elevated train service is not yet affected.
Floods from northern Thailand triggered by heavy monsoon rains since July have reached the northern edge of Bangkok by the last week of October and is slowly creeping into the city. Authorities have ordered the evacuation of 11,000 residents from 8 of 50 districts in the capital. Five other districts have been affected have yet to be evacuated.

Meanwhile, the death toll from the flood stood at 506, the Disaster Relief and Mitigation Department said on Sunday, according to Bangkok Post. Twenty-five of 64 provinces remain flooded.
