Monsoon spell over most of Thailand with isolated heavy rains in all regions

SATURDAY, SEPTEMBER 11, 2021

A strong southwest monsoon prevails across the Andaman Sea, Thailand and the Gulf of Thailand, while an active monsoon trough lies across the lower North, the upper Central, and the Northeast, the Thailand Meteorological Department said on Saturday.

Thundershowers are forecast for most of the country with isolated heavy rains in some areas.

People should beware of flash floods, the department said.

Waves in the Andaman Sea are expected to be 2-3 metres high and above three metres in thundershowers. All ships should proceed with caution and small boats should keep ashore, the department said.

Meanwhile tropical storm “Conson” over the South China Sea is moving west. It is expected to intensify and make landfall over middle Vietnam on September 12-13. The storm would bring continuous rain to Thailand with isolated heavy to very heavy rains in some areas.
