According to the Korea Meteorological Administration, on the 11th, a trough of low pressure approaching from near the Shandong Peninsula in China will bring rain to the central regions from the morning, and to northern Jeonbuk and central and northern Gyeongbuk from the afternoon.

The rain is expected to spread to most parts of the country by the early morning of the 12th, and then subside in most areas by the afternoon. Between the night of the 11th and the early morning of the 12th, there may be temporary lulls in rainfall in the Seoul metropolitan area and Gangwon Province.

As a trough accompanied by cold air of around minus 20 degrees Celsius in the upper atmosphere passes over the region and warm southwesterly winds flow in at lower levels, atmospheric instability will intensify. As a result, areas experiencing rain may also see gusty winds as well as thunder and lightning.

In the central regions, Jeonbuk, and Gyeongbuk, some areas may experience strong winds with instantaneous speeds of around 55 km/h (15 m/s), and in mountainous areas, winds may reach around 70 km/h (20 m/s). Caution is advised to prevent property damage and safety accidents.

Expected precipitation amounts for May 11th to 12th are as follows: 5-10 mm in Seoul, Incheon, Gyeonggi, and the five northwestern islands in the Yellow Sea; 5-20 mm in inland and mountainous Gangwon; 5-30 mm in Daejeon, Sejong, Chungnam, and Chungbuk; 5-30 mm in Gwangju, Jeonnam, and Jeonbuk; 5-30 mm in Busan, Ulsan, Gyeongnam, Daegu, and Gyeongbuk; and 5-10 mm in Jeju Island.

When it rains, visibility will decrease and roads will become slippery. Drivers should keep a sufficient safe distance and reduce speed to ensure traffic safety and prevent accidents.

With the onset of rain, the current dry weather advisories may be lifted in some areas. Between the early morning and morning of the 11th, fog with visibility less than 1 km may form, especially in the Jeonnam region.

On the 11th, morning lows will range from 8 to 16 degrees Celsius, and daytime highs from 19 to 26 degrees Celsius, which is similar to or slightly higher than the seasonal averages (lows of 9-14 degrees Celsius and highs of 19-24 degrees Celsius). The Korea Meteorological Administration urged, "As there may be significant differences in precipitation by region, please refer to the latest weather information and radar images."
