Today (June 20), strong and heavy rain poured across the country due to the influence of a low-pressure system.
As of 6:00 p.m., the highest rainfall was recorded in the mountainous region of Misiryeong in Inje at 224mm, while parts of Gangbuk-gu in Seoul also saw heavy rainfall exceeding 100mm.
Let's take a look at the radar imagery of today's rainfall.
As intense red rain clouds passed through various areas, localized heavy downpours occurred, with around 22mm per hour in Gwanak-gu, Seoul, and around 35mm per hour in Gangneung.
Although most of the rain has stopped as the rain clouds move toward the northeast, light rain of around 5mm will continue in the central regions until tonight. In the Yeongdong region of Gangwon Province, up to 60mm of additional rain is expected until tomorrow morning.
Looking at the current satellite imagery, the sky is generally cloudy, but it will gradually clear up starting tonight. Tomorrow, we can expect clear skies again with very strong ultraviolet rays.
Fog will be somewhat dense in various parts of the country between tomorrow dawn and morning, and strong winds are expected nationwide until tonight.
Tomorrow morning's low will be 18°C (64°F) in Seoul, feeling cool.
However, daytime temperatures will rise to 29°C (84°F) in both Seoul and Daegu, bringing back early summer heat.
Next week will not be as intensely hot as this week, and there is a forecast for rain in Jeju and showers in various inland areas on Monday.
