According to the Thai Meteorological Department, continuous heavy rain all over Thailand will be occurring from October 7-9th. This could cause more flooding in some areas of the country as the rain intensifies, particularly in areas that suffer heavy thunderstorms.
The rain is due to a Category 2 tropical depression that is moving slowly west from the South China Sea, and could change from heavy to very heavy rain in some areas of Thailand.
This is expected to impact the lower Northeast of the country, the East, the Central including Bangkok and its vicinity, and the South.
Even more rain is also expected in the South due to the southwest monsoon across the Andaman Sea, southern Thailand and the Gulf of Thailand.
Waves are forecast to be high, with 2-4 meter peaks in some areas climbing to more than 4 meters high during thunderstorms.
The Meteorological Department is asking ships in the area to remain ashore from 7-10th October, and residents in coastal areas are advised to look for surf heading inshore that could cause flooding.
Over the next three days, heavy rain is expected to particularly affect the following areas:
