Heat Wave Advisories Issued for Seoul Metropolitan Area; Rain Expected Nationwide Starting Friday Night

Today (June 18), the first heat wave advisory of the year was issued for the Seoul metropolitan area.

Sweltering heat with a perceived temperature of around 33°C (91°F) is expected to continue, mainly in the Seoul metropolitan area and North Gyeongsang Province, through tomorrow.

Meanwhile, rain is in the forecast between tomorrow and the day after, which will help cool down the heat.

The rain is expected to begin in Jeju tomorrow morning, expand to the Honam region by late afternoon, and spread across the entire country by night.

This rainfall is expected to be particularly heavy, especially in Jeju and the southern coastal regions.

As a large amount of water vapor flows in from the south, heavy rain with an intensity of up to 50mm per hour is expected, particularly between tomorrow night and the morning of the day after.

In terms of rainfall, up to 250mm or more is expected in the mountainous regions of Jeju, up to 120mm or more in the southern coastal areas and near Mount Jiri, and up to 100mm in other parts of the southern provinces. The Seoul metropolitan area is expected to see a relatively smaller amount of rain, ranging from 10 to 40mm.

Now, let's take a look at the position of the stationary front.

It stretches from southern China to the waters south of Japan.

As a low-pressure system accompanies it, it will approach the Korean Peninsula tomorrow, starting with rain in the Jeju region.

In the central regions, while the rain will begin tomorrow night, there may be scattered showers during the afternoon as well.

Morning temperatures will be around 23°C (73°F) in Seoul, and it will feel muggy due to high humidity.

Daytime temperatures will climb to 33°C (91°F) in both Seoul and Chuncheon.

Most of the rain will cease by Saturday evening, but it will continue until Sunday afternoon in the Gangwon Yeongdong region.

Next week is expected to be less hot than this week.
