People living in the North, the Northeast, the East and Central regions have been told to brace for heavy rain and gusty winds until Tuesday, as heavy downpours hit parts of Bangkok on Saturday.
The Meteorological Department said a moderate high pressure system was covering the upper Northeast and the South China Sea, while southeasterly winds were prevailing over Thailand and the Gulf. More rain with isolated heavy showers and gusty winds are forecast for the upper regions of the country until Tuesday, with thundershowers expected over the South.
Heavy rain in Buri Ram on Saturday played havoc with qualifying for Sunday's MotoGP race, the biggest event of the year in the northeastern province.
The department advised people in the North, the Northeast, the East, the Central Plains, including Bangkok and surrounding areas to take extra caution in the face of heavy rain and winds.
People should stay away from unsecured buildings and outdoor areas, it said.
In Bangkok, heavy rain triggered flooding in the Bang Na area around noon on Saturday, JS 100 traffic radio reported. Motorists were told to take extra caution travelling to the area as the road at the Bang Na intersection leading to Bitec Hall was under water.
