----------------------------
During 20-25
December 2023, the strong high-pressure system from China will extend to
Thailand and the South China Sea with cool to cold weather
and strong wind. A decrease in temperature by 5–8 °C is likely in the Northeast, a decrease in temperature by 4–6 °C is likely the North and a decrease
in temperature by 3–5 °C is likely in the Central including Bangkok and its
vicinity and the East while 2–4 °C decrease in temperature is likely in the
upper South. On mountaintops of the North and the Northeast, cold to very cold
and isolated frost is forecast. The minimum temperature of the North mountaintops is in range of 3-10 °C while
the Northeast ranges by 5-13 °C. People in the country should keep healthy and
beware of fire due to strong winds and dry air.
The northeast monsoon prevailing over
the Gulf and the South will strengthen. Meanwhile, an active low-pressure cell over
the lower South China Sea will move through the lower South and Malaysia into
the lower Andaman Sea during 22-25 December 2023. Isolated heavy to very
heavy rains are likely in the lower South. People in the lower south should
beware of heavy to very heavy rains that may cause flash floods and overflows,
especially along the waterways near foothills and lowlands. At the same time, the
strong wind forces the waves in the Gulf up to 2-4 meters high and above 4
meters high in thundershowers. In the Andaman Sea, the waves are likely about 2 meters high and above 2 meters high in
thundershowers and offshore. People along the South (east coast) should beware
of inshore surges. All ships should proceed with caution and keep off
thundershowers. Small boats in the Gulf should keep ashore during 22-25 December
2023.
The
advisory is in effect on 20 December 2023, at 5.00 a.m.
This next issue will be on 20 December 2023,
at 5.00 p.m.
