As a trough of low pressure approaches from the Shandong Peninsula in China, rain is expected in most regions nationwide from the early morning to the morning of the 11th. In areas with lower temperatures, such as eastern Gyeonggi Province, Gangwon Province, and the northeastern mountainous regions of North Gyeongsang Province, snow may fall instead of rain.

After the trough passes, easterly winds will blow along the edge of a high-pressure system expanding from northern China toward the East Sea, bringing rain or snow to the east coast and mountainous areas of Gangwon Province, as well as the east coast and northeastern mountainous areas of North Gyeongsang Province, from the afternoon of the 11th through the morning of the 12th.

Since these regions have been experiencing persistently dry conditions, this will serve as a much-needed rainfall. Between dawn and morning on the 12th, rain or snow will also fall in Ulsan, and there will be a few raindrops in Busan. However, in the case of the east coast and mountainous areas of Gangwon Province, heavy wet snow containing a lot of moisture could cause damage.

In particular, from the night of the 11th to the morning of the 12th, heavy snowfall of 1 to 3 centimeters per hour is possible, so preparations are necessary. The expected precipitation from the 11th to the 12th is as follows: 5 to 15 millimeters for the east coast of Gangwon Province; 5 to 10 millimeters for the Seoul metropolitan area, the five West Sea islands, inland and mountainous areas of Gangwon Province, Chungcheong Province, Gwangju, South Jeolla Province, northeastern mountainous areas of North Gyeongsang Province, northern east coast of North Gyeongsang Province, Ulleungdo, and Dokdo; around 5 millimeters for North Jeolla Province; and less than 5 millimeters for Daegu, inland North Gyeongsang Province, southern east coast of North Gyeongsang Province, Busan, Ulsan, and South Gyeongsang Province. Precipitation refers to the total amount of water falling from clouds to the ground, including both rain and snow.

The expected snowfall is 3 to 8 centimeters (with a maximum of over 10 centimeters) for the mountainous and east coast areas of Gangwon Province; 1 to 5 centimeters for the northeastern mountainous areas of North Gyeongsang Province; 1 to 3 centimeters for Ulleungdo and Dokdo; around 1 centimeter for the northern east coast of North Gyeongsang Province; and less than 1 centimeter for Ulsan and the southern east coast of North Gyeongsang Province.

This rain and snow event will be accompanied by strong winds with instantaneous speeds of over 55 kilometers per hour (70 kilometers per hour in mountainous areas). On the west coast of South Chungcheong Province, the coasts of Jeolla Province, and Jeju Island, strong wind advisories may be issued from the afternoon of the 11th due to powerful winds, so precautions are necessary.

At sea, strong winds of 30 to 65 kilometers per hour (9 to 18 meters per second) and high waves of 1.5 to 4.0 meters are expected in the West Sea, the central East Sea, the northern part of the southern East Sea, and the western distant waters of the southern sea in the morning of the 11th, and in other sea areas from the night of the 11th, so caution is advised.

On the 11th, temperatures will remain above average for this time of year. The morning lows nationwide are expected to range from -1 to 9 degrees Celsius, and the daytime highs from 6 to 17 degrees Celsius.

The expected minimum and maximum temperatures for major cities are as follows: Seoul, 5 and 8 degrees; Incheon, 6 and 7 degrees; Daejeon, 5 and 12 degrees; Gwangju, 7 and 13 degrees; Daegu, 4 and 15 degrees; Ulsan, 5 and 17 degrees; and Busan, 8 and 17 degrees.

On the 12th, temperatures are expected to drop to levels similar to the seasonal average, with morning temperatures falling by 5 to 10 degrees in a single day, so caution is advised.
