"Cool to Cold in upper Thailand and strong Wind-Waves in Gulf"
No. 6 Time Issued December 31, 2020
The strong high-pressure system from China covers the upper Thailand with cooler weather and strong winds. Temperatures are expected to decrease more 2-4 degrees Celsius. The plains of the North and the Northeast have minimum temperatures in ranges of 9-16 degrees Celsius but mountaintops have cold to very cold weather with minimum temperatures in ranges of 2-10 degrees Celsius and isolated frost. In the Central and East regions, minimum temperatures are in ranges of 16-18 degrees Celsius. People should keep healthy due to the colder weather.
The stronger northeast monsoon across the Gulf of Thailand and the South forces the waves 2-3 meters high in the upper Gulf, 2-4 meters high in the lower portion, and more than 4 meters high in thundershowers. Residents along the shoreline should beware of inshore surf. All ships should proceed with caution. Small boats keep ashore lasting 3 January 2021.
This advisory is in effect on 31 December 2020, at 11.00 a.m.
The next issue will be at 31 December 2020, at 5.00 p.m.
