Thailand's Great Flood likely to peak this weekend


Top ten most expensive natural disasters in Thailand since 1900, as tabulated by the Centre for Research on the Epidemiology of Disasters (CRED). This month's disaster (number one on the table above) is not yet in the CRED data base

The most damaging natural disaster in Thailand history is growing more serious, as the flood waters besieging the capital of Bangkok continue to overwhelm defenses and inundate the city. Heavy rains during September and October have led to extreme flooding that has killed 373 people and caused that nation's most expensive natural disaster in history, with a cost now estimated at $6 billion. Thailand's previous most expensive disaster was the $1.3 billion price tag of the November 27, 1993 flood, according to the Centre for Research on the Epidemiology of Disasters (CRED). Floodwaters have swamped fields and cities in a third of Thailand's provinces, affected 9 million people, and damaged approximately 10% of the nation's rice crop. Thailand is the world's largest exporter of rice, so the disaster may put further upward pressure on world food prices, which are already at the highest levels since the late 1970s. The highest tide of the month occurs this weekend at 8:07 am ICT in the capital of Bangkok, and the additional pressure that incoming salt water puts on the flood walls protecting the city is a major concern. Fortunately, the monsoon has been quiet this week over Southeast Asia, and the latest GFS model precipitation forecast show little additional rain over the country in the coming week. Heavy monsoon rains are common in Thailand and Southeast Asia during La Niña events, and we currently have a weak La Niña event occurring. Ocean temperatures in the waters surrounding Thailand during September and October have been approximately 0.3°C above average, which has increased rainfall amounts by putting more water vapor into the air. The remains of Tropical Storm Haitang and Typhoon Nesat also brought heavy rains in late September which contributed to the flooding.
