There is a significant temperature difference between mornings and days.

This morning (September 17), temperatures in most regions started around average levels.

As the day warms up, temperatures in Seoul and Gwangju are expected to rise to 29°C (84°F), bringing lingering late-summer heat.

You should take good care of your health by wearing appropriate clothing suitable for the changing times of day.

Today, as easterly winds strengthen in the southern coast and Jeju regions, sudden strong gusts of around 15 to 20 meters per second may blow at times.

Gusty winds are also expected in inland areas as well.

Please be cautious of safety accidents.

Meanwhile, the 25th typhoon is located far over the southeastern seas of Japan.

As cold air from the north blocks the typhoon from moving northward, it will not affect South Korea.

Let us take a closer look at daytime temperatures by region.

The daytime high in Hongseong is expected to reach 28°C (82°F), and Daegu 27°C (81°F).

Rain is forecast for the east coast, south coast, and Jeju regions tomorrow.

As cold and warm air collide, heavy downpours of over 100mm are expected to pour down in the Jeju region.

Please make thorough preparations to prevent any rain damage.
