[Weather] Will the rain stop and bring some relief?... "Heatwave around 30 degrees continues"

Chance of Rain Continuing Until the 25th
Heatwave Returns After the Rain Stops

Wednesday, the 23rd, is Chuseo (處暑), the solar term indicating the heat will ease and cool autumn will arrive, but heavy rain is expected nationwide amid the heatwave.

According to the Korea Meteorological Administration on the 22nd, the expected rainfall from the 22nd to 23rd is 50 to 120 mm in Incheon, northern Gyeonggi, and the five western islands, 30 to 100 mm in Seoul and southern Gyeonggi, and 30 to 80 mm in inland Gangwon, Chungcheong, Jeolla regions, and Jeju Island.

More than 150 mm of rain is expected in northern Gyeonggi and the mountainous areas of Jeju Island, and over 120 mm in Seoul, southern Gyeonggi, central and northern inland Gangwon, the western coast of Chungnam, coastal Jeolla, near Jirisan, and the mid-mountain areas of Jeju Island.

This rain is expected to continue until the 24th.

However, depending on the expansion of the North Pacific High, the rain may continue until the 25th. This is because a pressure trough forms along the rear of a low-pressure system passing through northeastern China, creating a long rain band crossing the North Korean side. Additionally, moisture inflow due to strengthened southwesterly winds may cause heavy rainfall.

The minimum temperature on the morning of the 24th is expected to be 23 to 26 degrees Celsius, and the maximum temperature during the day is expected to be 27 to 33 degrees Celsius.

Due to the rain, daytime temperatures will temporarily drop in most regions except Gyeongsang Province, possibly leading to the lifting of heatwave warnings. However, once the rain stops, the heatwave with maximum temperatures around 30 degrees Celsius is expected to continue.

One of the causes of this rain is the inflow of hot and humid air from the south, so it is unlikely to significantly lower the overall temperature.

Sea waves are expected to be 0.5 to 1.0 meters in the East Sea coastal waters, and 0.5 to 1.5 meters in the West Sea and South Sea coastal waters.

Wave heights in the offshore waters (about 200 km from the coastline) are expected to be 0.5 to 1.5 meters in the East Sea, 0.5 to 2.0 meters in the West Sea, and 1.0 to 2.0 meters in the South Sea.

Fine dust concentration is expected to be at a 'Good' level across all regions due to smooth atmospheric dispersion and the influence of precipitation.
