(Seoul = Yonhap News) Reporter Jaeyoung Lee = After rain until noon on the 13th, temperatures will drop as cold air flows in from the northwest.

As a mid-low atmospheric pressure trough approaches in the West Sea, rain is falling in most areas as of 8 a.m. on this day.

As the trough moves east, the rain will stop by daylight in most areas, but there may be places in Gyeongnam where precipitation continues until late afternoon.

The amount of rain expected to fall further by region is 10 to 50 mm in Chungcheong, 5 to 40 mm in southern Gyeonggi, inland Gangwon, mountainous Gangwon, northern Gangwon east coast, and Jeonbuk, 5 to 30 mm in Gwangju, Jeonnam, Busan, Ulsan, South Gyeongsang, Daegu, Gyeongbuk, Ulleungdo, and Dokdo.

Be aware that rain may fall at a rate of 10 to 20 mm per hour along with gusts of wind, thunder, and lightning.

After the rain stops, our country will be affected by high pressure moving west from central China.

A 'west high, east low' barometric pressure system will be formed, and northerly winds will blow, and cold air is brought in by the northwest wind blowing along the edge of the high pressure, and temperatures are expected to drop.

The temperature this morning was significantly higher than usual at this time of year.

As of 8 a.m., temperatures in major cities are 22.7 degrees in Busan, 21.9 degrees in Gwangju, 21.4 degrees in Ulsan, 20.1 degrees in Daegu, 17.8 degrees in Daejeon, 15.3 degrees in Seoul, and 14.9 degrees in Incheon.

The highest daytime temperature will be 19 to 26 degrees, similar to or slightly higher than the average temperature (20 to 23 degrees).

Afterwards, on the morning of the 14th, the temperature will drop to 5 to 14 degrees. Compared to this morning, it is 5 to 10 degrees lower. The daytime temperature on the 14th is expected to remain at a maximum of 17 to 22 degrees.

As the distance between high pressure in the west and low pressure in the east gets closer, it will be quite chilly nationwide on the 14th with instantaneous winds of around 55 km/h (70 km in mountainous areas).

In the case of the sea, on the night of the 13th in the remote waters of the central West Sea, in the waters off Chungnam, in the southern waters of the West Sea, in the distant waters in the western South West, in the waters off the western coast of Jeju, in the distant waters south of Jeju, in the distant waters in the southwestern interior of Jeju, and in the central waters of the East Sea, in the early morning of the 14th, in the distant waters of the southeastern interior of Jeju, in the distant waters east of the Namhae, and in the southern waters of the East Sea (off the coast of Ulsan) Excluding), from the morning of the 14th, the wind will blow strongly at 30 to 55 km/h (8 to 15 m/h), and the waves will rise as high as 1.5 to 3.5 m. A storm warning may be issued for these waters.

You should be especially careful because the moon's gravitational force will be strong until the 14th, so the sea level will be higher than usual.
