The annual winter monsoon will continue to bring cold and dry weather to the region in the next couple of days, Hong Kong Observatory says.
A monsoon is a seasonal wind flow formed by the difference in surface pressure because of the differential heating of seas and lands. The northeast monsoon generally prevails over the coast of China in winter while the southwest monsoon dominates in summer.
The Observatory also says that the daily range of temperatures will be relatively large over inland areas. The temperature on Wednesday will be 11 to 17 degrees Celsius, and is predicted to be 12 to 18 degrees Celsius on Thursday and Friday. The temperature is expected to go up on Saturday with a range of 14 to 19 degrees Celsius.
“An easterly airstream is expected to affect the coast of Guangdong during the weekend to early next week. Temperatures will rise and it will become cloudier gradually over the region,” the Observatory says on its website.
As of 11am on Wednesday, the Cold Weather Warning and Red Fire Danger Warning are both in force as cold weather is expected and the risk of fire is high due to the dry weather.
The Observatory advises people to put on warm clothes and ensure adequate indoor ventilation.
“If you know of elderly persons or persons with chronic medical conditions staying alone, please call or visit them occasionally to check if they need any assistance,” the Observatory says.
Also, make sure heaters are safe before use, and place them away from any combustible objects. Do not light fires indoors as a means to keep warm.
