Noul is as devastating as tropical storm Podul, which caused widespread flooding in the Nakhon Phanom province last August, Xinhua news agency quoted the TMD as saying.

Noul is currently increasing in strength as it approaches Vietnam and is likely to develop into a typhoon, said the TMD, adding that it was closely monitoring whether it weakens into a tropical storm as it sweeps through upper Thailand.

The northeast, the TMD said, is forecast to be showered with more than 90 mm of rainfall and may cause flooding in the region.

Meanwhile, the Ministry of Interior has also warned riverside residents in the 24 provincesto brace for flash floods or runoffs as tropical storm Noul, currently a Category 3 storm, will likely turn into Category 5 or a typhoon.

The Thai Royal Irrigation Department said it has taken steps on water management at dams and reservoirs in the northeast, which is expected to be hit first by Noul, by discharging water to make room to store water brought by the storm.

Also, the Department of Prevention and Mitigation of Public Disasters has coordinated with provincial public relief centers and a network of civilian volunteers, local administration organizations and private sectors, to find ways to assist residents that may be affected by Noul.
