Heavy Rain of Around 100mm Expected Nationwide; Heat Wave to Subside

Today (June 19), Seoul reached a high of 34°C (93°F), marking the peak of the current heat wave.

As daytime temperatures soared, the atmosphere became highly unstable, leading to heavy downpours.

Strong and heavy rain is expected across the country through tomorrow. Please take extra precautions to prevent any damage.

In particular, this rain will fall very heavily until tomorrow morning.

Hourly rainfall across the country is expected to reach 20 to 30mm, which is enough to make it difficult to secure visibility while driving.

Additionally, up to 50mm of rain per hour is expected in the southern coast, near Jirisan Mountain, and Jeju Island.

As roads can be submerged in an instant, please be especially cautious of flood damage.

Looking at the expected rainfall, up to 250mm or more is forecast for the mountainous regions of Jeju, up to 120mm or more for the southern coast and near Jirisan Mountain, up to 150mm or more for Gangwon Yeongdong, and up to 100mm for Seoul and the rest of the country.

This rain will mostly cease by tomorrow night.

This rainfall is occurring because a stationary front, or monsoon front, has temporarily moved northward, accompanied by a low-pressure system, causing heavy rain similar to the monsoon season.

In particular, strong winds are expected in the eastern coast of Gangwon, the southern coast, and Jeju Island tomorrow.

The heat wave will subside. Tomorrow, the daytime high in Seoul will only reach 25°C (77°F).

Next week, there will be no intense heat exceeding 30°C (86°F), and there is a forecast for rain in Jeju on Monday and Wednesday.
