Prime Minister Hun Sen has called on soldiers at the border to be careful with their health during the cool weather to avoid becoming ill.
He said via his social network on Tuesday that the weather in Phnom Penh this morning was very cold and the wind made it colder.
“Please, everyone take time to do exercise in the morning for health and the soldiers who are protecting the border have to take care of their health and wear coats to prevent any diseases,” he said.
The Ministry of Water Resources and Meteorology announced on the weekend that temperatures in some provinces could drop as low as 13 degrees Celsius this week.
The Dangrek Mountain area on the border with Thailand will be worst hit by the cold snap, which is caused by a high pressure system coming from China.
Temperatures of about 15 degrees Celsius are expected until at least Friday in Stung Treng, Ratanakkiri, Mondulkiri, Preah Vihear, Oddar Meanchey and Pailin provinces.
Pursat, Battambang, Siem Reap, Banteay Meanchey and Koh Kong provinces will meanwhile see temperatures of between 17 and 18 degrees Celsius.
“In other provinces, the temperature will be about 19 to 20 degree Celsius, except in Kep, Kampot and Preah Sihanouk, which will not be so cold,” the statement said.
“The public and authorities should be careful and prepare for the cold weather, especially soldiers stationed on the border along the Dangrek Mountains.”
The ministry earlier said that cold bouts of weather would begin in the middle of December and last longer and be cooler than in previous years.
