On Sunday, today (18th), the whole country is sunny, and the morning temperature in most of the inland regions will drop below 10 degrees Celsius.

The temperature difference between day and night is expected to be 10 degrees or more in most areas of the country and 15 degrees or more in inland areas.

The maximum temperature during the day was forecast at 19 to 23 degrees, and the concentration of fine dust is expected to be'good' to'normal' in all areas.

There is a thick fog with a visibility distance of 200m or less in Central Inland, Jeolla Inland, and Gyeongbuk Inland, so traffic safety needs special attention.
