The monsoon season is set to begin on the Korean Peninsula this week. 

According to the Korea Meteorological Administration(KMA), the monsoonal front will swiftly move from the southern waters off Jeju Island to South Korea’s central region on Tuesday. 

The rain will begin hitting the western coast in the predawn hours and move across the nation throughout the morning. 

As the seasonal front is expected to travel to the demarcation line, over 20 millimeters per hour of heavy precipitation is expected to hit central regions through Tuesday afternoon, including in Seoul and northern areas of Gyeonggi Province. 

Showers will move toward North Korea throughout the afternoon, allowing a temporary letup in Chungcheong Province, southern regions and Jeju. 

However, on Wednesday, the rain front will move back to the South bringing downpours to Chungcheong and southern regions during the morning hours. In some areas, more than 30 millimeters of rainfall is expected per hour. 

Mount Jiri and adjacent areas could get up to 200 millimeters of rain, Chungcheong Province and southern regions between 80 and 150 millimeters and the Seoul metropolitan area 120 millimeters. 

The monsoon season usually lasts for a month. The KMA expects frequent, local torrential downpours will scatter large amounts of rain in a small area due to the front’s repeated movements.
