BANGKOK: Typhoon Dolphin is not expected to enter Thailand and is forecast to pass Taiwan before making landfall on the eastern coast of China.
A strengthening south-westerly monsoon will bring heavy to very heavy rain to parts of Thailand, particularly from Aug 5 to 9.
The regions most affected by the monsoon will be the upper North, upper Northeast, East and the South's west coast, with risks of flash floods.
The strengthened monsoon will also generate waves of two to three metres in the Andaman Sea and the Gulf of Thailand, prompting warnings for mariners.
The Thai Meteorological Department (TMD) has forecast heavy rain in some areas of Thailand over the next seven days, with very heavy rain possible in parts of the upper North, upper Northeast, East and the South's west coast.
A monsoon trough will extend across Myanmar and northern Laos into a low-pressure area over northern Vietnam from Aug 3 to 5.
The trough will shift southwards across the upper North and upper Northeast from Aug 6 to 8.
Meanwhile, the south-westerly monsoon prevailing over the Andaman Sea, Thailand and the Gulf of Thailand is expected to strengthen from Aug 4 to 9.
Wind and wave conditions in the upper Andaman Sea are expected to strengthen from Aug 3 to 9, with waves reaching two to three metres and exceeding three metres during thundershowers.
Waves in the upper Gulf of Thailand and the lower Andaman Sea are forecast to be about two metres high, rising above two metres during thundershowers.
Typhoon Dolphin over the Pacific Ocean is expected to pass Taiwan and make landfall on the eastern coast of China between Aug 7 and 8.
The storm is not expected to enter Thailand.
Travellers heading to those areas are advised to check weather conditions before departure.
People across Thailand, particularly in the North, upper Northeast, East and the South's west coast, should remain alert to hazards from heavy to very heavy rain and accumulated rainfall from Aug 5 to 9.
These conditions could cause flash floods, forest run-off and rivers overflowing their banks, especially on foothill slopes near waterways and in low-lying areas.
Mariners in the Gulf of Thailand and the Andaman Sea should exercise greater caution and avoid sailing in areas affected by thundershowers throughout the period.
Small boats in the upper Andaman Sea should remain ashore from Aug 3 to 9, while those in the Gulf of Thailand should remain ashore from Aug 7 to 9.
