During 8 - 14 May 2023, the low-pressure cell over the lower Bay of Bengal will be likely to develop into a tropical cyclone, that is expected to move from middle Bengal and the upper Andaman Sea to the coastal region of Myanmar. It leads to the stronger southwesterly wind prevailing across the Andaman Sea and Thailand with more rains in the country. Heavy to very heavy rains are also possible in some places. In the upper Andaman Sea, the strong wind forces the waves up to 2-4 meters high and in thundershowers more than 4 meters high. Meanwhile the lower Andaman Sea has the waves about 2 meters high and in thundershowers more than 2 meters high. All ships should proceed with caution and keep off thundershowers. Small boats in the upper Andaman Sea should keep ashore.
