Flood waters crept into two key areas in East Bangkok with many areas in the Thai capital under 80cm of water or more, affecting more than 800,000 people.
The underground subway trains and the sky train services were not affected though the bus services were disrupted in some areas.
MRT, which operates subway trains, said all its 18 stations are still operating as usual.
The central Bangkok area is still dry though there are fears that flood waters would march into the area in the next few days.
Meanwhile, the City Hall is racing to collect floating garbage and sewage in city areas amid fears of an outbreak of disease.Garbage collectors have been facing difficulty in collecting household waste in several flooded districts of Bangkok.
There was no estimate on the amount of garbage floating around Bangkok as a massive amount of rubbish still had to be picked up. Tonnes of piled-up garbage which had not been collected prior to the flooding has added to the rubbish in the flood waters.
Garbage collectors have abandoned trucks and are now using boats to pick up the litter as several neighbourhoods could not be accessed because of rising water levels.
Officials aimed to finish collecting all floating rubbish and sewage in Lak Si si district by the end of today.
They have already cleaned up the districts of Bang Phlat, Don Mueang, Taling Chan and Bangkok Yai. Bangkokians have been asked to sort their garbage to help speed up collection.
Meanwhile, floodwater had reached near Lat Krabang Industrial Estate.The industrial estate is about 10 kms north of Bangkok’s Suwarnabhumi international airport.
The airport is open while the domestic Don Muang airport has been closed after flood waters entered inside.The industrial estate spans more than 1000 acres and has over 250 factories including Honda, Isuzu and Unilever.
Authorities said 506 people have died so far.
The Chatuchak district in northern Bangkok, which also has the chatuchak weekend market, saw swirling flood waters enter the area though the market, highly popular among tourists as well as Thais remained open yesterday.
