Heavy Rain Risk Area
The monsoon trough lies across the upper North and upper Laos into the low-pressure cell over the coast of upper Vietnam while the moderate southwest monsoon prevailing over the Andaman Sea, Thailand and the Gulf is strengthening. Isolated heavy to very heavy rains are forecast in the Northeast while isolated heavy rains are possible in the North, the Central, the East and the South regions.
The rather strong winds force the waves in the upper Andaman Sea up to 2–4 meters high and above 4 meters high in thundershowers. In the lower Andaman Sea and the upper Gulf, the waves are expected to be about 2 meters high and above 2 meters high in thundershowers.
People should beware of heavy to very heavy rains and accumulation that may cause flash floods, overflows and landslides especially along the waterways near foothills and lowlands.
All ships should proceed with caution and keep off thundershowers, small boats in the upper Andaman Sea should keep ashore.
