----------------------------
During 20-25
Dec, 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 Dec. 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 2meters high and above 2 meters high in
thundershowers and offshore. People along the South (east coast) shore 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
Dec.
The
advisory is in effect on 19 December 2023, at 5.00 a.m.
