On Monday, Thai Prime Minister Yingluck Shinawatra ordered canal dredging and reinforcement of flood-prevention

embankments to protect the city, state-run news agency MCOT reported. In addition, three new flood-prevention walls

were being built at two locations in Rangsit, in northern Bangkok, and in Taling Chan, in the western part of the city.

Tourists warned as floods continue to wreak havoc in Thailand

The government needs another 1.5 million sandbags, MCOT reported. The prime minister called on the private sector to

supply them, but said the government will buy all the needed sandbags by Wednesday, the news agency said.

Meanwhile, around 1,200 people have taken shelter in a gymnasium at Bangkok's Thammasat University. Most of them

are from neighboring Ayutthaya province and other flood-affected areas around the capital, said Thanawat Srisuwan, a

volunteer at the makeshift shelter.

The authorities have set up almost 200 other temporary shelters around the city to receive flood victims. The Bangkok

Metropolitan Administration said plans were in place to evacuate people from nine areas, mainly in eastern Bangkok, if

needed.

Elsewhere, patients in two hospitals in Thailand's Ayutthaya and Nakhon Sawan provinces had to be evacuated after

water reached the first floor, the flood operations command said.

Multiple tropical weather systems have moved over the region in recent weeks, enhancing monsoon rains and leading to

the flooding. Another low pressure system is forecast to move into Southeast Asia on Tuesday and Wednesday, said

Brandon Miller, senior meteorologist for CNN International.

According to the government website Thaiflood.com, water from northern Thailand has finally reached lower parts of

central Thailand, penetrating dykes in Pathumthani and Nonthaburi provinces and flooding outer areas of Bangkok,

including the market in Nonthaburi and Chiang Rang road.
