If you have plans for the weekend, you should keep a close eye on the weather. As the monsoon front moves northward, the entire country is coming under the influence of the rainy season. The forecast has been updated, with rain now expected to reach the Seoul metropolitan area as early as Sunday, sooner than initially anticipated.

Reporter Jeong Gu-hui explains the reason why.

This is CCTV footage from a mountainous area in Jeju Island.

Heavy rain is intensifying, leading to the issuance of a heavy rain advisory, and winds are also picking up.

The monsoon front that brought rain to Jeju is gradually moving north.

Looking at the radar imagery, the rain clouds from Jeju are moving upward and have expanded to the southern coast of South Jeolla Province.

Accordingly, rain is expected in the southern regions tomorrow, July 4, and will expand to the southern parts of Chungcheong Province by the afternoon.

By Sunday afternoon, monsoon rain will cover the entire country, including the Seoul metropolitan area and Gangwon Province, which is about half a day earlier than previously forecast.

This monsoon front is formed by the collision of warm air from the North Pacific High in the south and cold air from the northwest.

The Korea Meteorological Administration observed that the cold air from the north is stronger than expected and is expanding toward the Korean Peninsula more rapidly. As a result, the monsoon front is widening toward the Seoul metropolitan area, leading to predictions of widespread rainfall.

By tomorrow, more than 150mm of rain is expected in the mountainous areas of Jeju, and between 20mm and up to 80mm in the southern regions.

When combined with the rain on Sunday, some areas in the south, particularly along the southern coast, could see over 100mm of rainfall throughout the weekend.

Rain across the country is expected to continue until Monday.

However, a variable for next week's monsoon rain is the typhoons.

Typhoon No. 10, Maysak, which formed over the waters south of China today, is expected to dissipate as it moves inland into China.

Meanwhile, Typhoon No. 9, Bavi, which is currently moving north toward Taiwan, is not expected to reach Korea at this time. However, if the typhoon gains strength, it could push the nearby North Pacific High toward the Korean Peninsula.

As a result, the monsoon front could fluctuate up and down across the Korean Peninsula during the latter half of next week, bringing more rain.
