storms are likely over the area, accompanying with thunderstorms, gusty winds
and hail in some places, as well as some isolated lightning strikes. People
should beware of the severe condition by keeping off outdoor places, big trees,
unsecured buildings and billboards and taking off metal decorations and mobiles. Farmers should prevent for crop damage.

From 9 to 15
May,
the active low-pressure cell over the lower portion of Bengal Bay will likely develop
into a tropical cyclone. It will then move from middle Bengal through the upper
bay of bengol. As a result, the stronger southwesterly wind prevails across the
Andaman Sea with more rains in Thailand. Heavy rains are also possible in some
places. In the upper Andaman Sea, the strong wind forces the waves up to about
2 meters high and in thundershowers more than 3 meters high. Meanwhile the lower
Andaman Sea has the waves 1-2 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.
The
advisory is in effect on 9 May 2023, at 5.00
p.m.
This next issue will be at 10 May
2023, at 5.00 a.m.
