Heavy rain in November... Heavy rain exceeding 50 mm per hour in eastern Jeju last night

Last night, heavy rain of up to 50 mm per hour fell in some areas of Jeju Island.

According to the Jeju Regional Meteorological Administration on the 5th, the highest precipitation in one hour was 51.3 mm at Seongsan (east) point on this day, the highest recorded in November since meteorological observations were made at this point. The previous record for first place was 28.5 mm on November 14, 1984.

The highest rainfall of 15.5 mm in 10 minutes was also the highest ever recorded in November. The previous record for first place was 12 mm on November 15, 1984.

In the Seogwipo (southern) branch, the highest precipitation in one hour on this day was 25.6 mm, breaking the 4th highest precipitation of all time in November and the 2nd highest precipitation in 10 minutes at 7.8 mm.

In addition, the highest rainfall in one hour in the eastern region reached 59 mm in Pyoseon and 50 mm in Namwon, Jeju.

A heavy rain warning was issued early in the morning in the eastern and southern parts of Seogwipo City, and a heavy rain warning was strengthened in the eastern part of Seogwipo City. Currently, all heavy rain warnings have been lifted.

The accumulated precipitation by location from the previous day to 10 am this day recorded 108 mm in Pyoseon, 104.5 mm in Namwon, Jeju, 96 mm in the azalea field of Hallasan Mountain, 91 mm in Seongsan, 78.5 mm in Hannam, and 71.3 mm in Seogwipo.

Initially, the expected rainfall announced by the Korea Meteorological Administration the afternoon before was 20 to 60 mm in mountainous and mid-mountainous areas and 10 to 40 mm in other areas, but heavy rain far exceeded expectations, especially in the eastern coastal area of ​​Seogwipo.

An official from the Korea Meteorological Administration said, "Due to the influence of the low pressure passing over the South Sea, there were places in the southern and eastern parts of Seogwipo where there was very strong rain of around 50 mm per hour. The lower jet (strong wind in the lower atmosphere) was stronger than expected, and it appears that a lot of rain fell as the terrain effect was added."

The Korea Meteorological Administration predicted that there would be rain in Jeju until late afternoon on this day.

However, the strong rain clouds that were affecting Jeju Island have moved out to the eastern sea, and the expected rainfall is forecast to be around 5 mm.

In addition, while a strong wind warning is in effect throughout Jeju Island, the wind will blow very strongly in mountainous areas until the morning of the 7th and in other areas until the evening of the same day, with an instantaneous wind speed of 20 m per second (25 m per second in mountain areas), and asked people to be careful about facility management and safety accidents.
