[Asia Economy Reporter Han Jinju] On Friday the 18th, rain will fall nationwide until the morning. Although it rains frequently, the Korea Meteorological Administration (KMA) explains that the monsoon season has not yet started.

The KMA forecasted that the whole country will be mostly cloudy with rain in most areas until the morning, rain continuing until the afternoon in Yeongseo, Gangwon Province, and until the evening in Jeju Island. The expected precipitation is around 5mm.

In the afternoon, in the eastern part of Jeonbuk and inland Gyeongsang, unstable atmospheric conditions will occur as cold air in the upper layer moves southward and warm air flows in the lower layer, causing showers of about 5mm in some places.

Recently, frequent rain has caused misunderstandings that the monsoon has started, but the KMA expects the monsoon to begin later than usual. The average monsoon start dates are ▲Jeju June 19 ▲Southern regions June 23 ▲Central regions June 25. Although the monsoon usually starts in late June, it often begins in early July, so this is not considered an unusual weather situation.

A KMA official explained, "Cold and dry air is coming down from the northwest, preventing the stationary front from moving northward. This rain is accompanied by a low-pressure system, so the amount is small, and there will be no significant rainfall after this rain passes. Rainfall is expected this weekend or early next week, but since the stationary front will not move northward, the monsoon has not started."

Daytime temperatures will be around 25 degrees Celsius, and the weekend will be sunny with temperatures rising to around 30 degrees Celsius in inland areas. However, morning temperatures on the 19th and 20th will drop to 15 degrees Celsius. Fine dust levels will be 'Good' to 'Moderate' across all regions on this day.

The KMA urged, "As cold air moves southward, mornings and evenings will be cool with large temperature differences between day and night, so please take care of your health."

Fog with visibility of 1 km is expected until the morning of the 19th along the west coast, and in other inland areas from night until the next morning. Dense fog is expected over all seas on this day, and over the West Sea and South Sea on the 19th and 20th, so ships navigating or fishing should be cautious.
