[Asia Economy Reporter Han Jinju] On Friday the 2nd, there will be showers in various parts of the metropolitan area and across the country. The rainy season will begin nationwide from the afternoon of the 3rd.

On the 2nd, the Korea Meteorological Administration (KMA) forecasted that there will be occasional clouds nationwide, with showers expected from morning to evening in the metropolitan area, southern inland Gangwon, northern Chungcheongbuk-do, the west coast of Chungnam, Jeolla region, and mountainous areas of Jeju Island. Expected precipitation is 5 to 40mm. The highest daytime temperature will range from 24 to 32 degrees Celsius.

Starting tomorrow, as warm moist air from a low-pressure system flows near the stationary front, heavy rain is expected. Rain will begin on the morning of the 3rd in Jeju Island, in the afternoon in the metropolitan area, Chungcheong region, and southern regions, and will expand nationwide from night. The central region, Jeolla region, southern coast of Gyeongnam, areas near Jirisan, and Jeju Island will receive about 50 to 100mm of rain. Some places may receive more than 150mm.

From late night on the 3rd, as the rain cloud band strengthens, some areas may experience heavy rain exceeding 50mm per hour accompanied by thunder, lightning, and gusty winds.

The KMA stated, "Until the day after tomorrow (the 4th), heavy rain exceeding 150mm is expected mainly in the central region, Jeolla region, southern coast of Gyeongnam, areas near Jirisan, and Jeju Island. Since flooding is likely in habitual flood-prone areas such as rivers and underpasses, as well as mountainous and valley areas, thorough prior inspection is necessary, and access should be avoided before the rain starts," urging caution.

Between the afternoon of the 3rd and the 4th, strong winds with speeds of 10 to 16 meters per second and maximum gusts up to 20 meters per second will blow, so attention to facility management and safety accidents is required. Starting from the morning of the 3rd, the sea waves in the outer West Sea will rise very high to 2 to 4 meters from afternoon to night.

The KMA said, "On the 3rd and 4th, the timing and areas of concentrated precipitation may change depending on the position of the stationary front and low-pressure system, so please refer to the upcoming weather information."

The KMA forecasted that from the latter part of the 4th, the stationary front will strongly develop southward, causing heavy rain centered on Jeju and the southern coast. As the low-pressure system passes every 3 to 4 days, it will push the stationary front northward, resulting in frequent rainfall.

Typically, the rainy season starts in late June, but this year it began the latest in 34 years. The central region's latest start was July 5 in 1987, the southern region's was July 9 in 1992, and Jeju's was July 5 in 1982. This delay was due to cold and dry air remaining over Korea, which postponed the northward movement of the stationary front.
