Heavy rain continues across South Korea's southern coastal region this Tuesday morning, with thunderstorms expected to follow in the afternoon [1].
The prolonged precipitation has saturated the soil, creating a high risk of geological instability in coastal cities. This weather pattern follows a three-day holiday period that saw record-breaking rainfall across the Namhae region [1].
Authorities have issued a landslide warning for the city of Tongyeong [1]. The warning comes after the city recorded 760 mm of cumulative rainfall during the holiday period [2]. Nearby Geoje experienced even more severe conditions, with cumulative rainfall reaching 950 mm [2].
Weather caster Won Chae-young said record-breaking heavy rain poured over the southern coast throughout the three-day Liberation Day holiday [1]. The lingering weather system continues to impact Gyeongsangnam-do, with forecasts predicting up to 60 mm of additional rain in parts of the southern coast today [1].
While the morning is characterized by steady rain, the forecast shifts toward showers and thunderstorms for the afternoon [1]. Despite the storms, temperatures are expected to remain high, with a forecast maximum of 33 °C [3].
Jeju Island also remains under a heavy-rain watch as the system moves through the region [1]. Local authorities are monitoring slope stability in Tongyeong and Geoje to prevent casualties as the ground remains weakened from the holiday deluge [1].
“Cumulative rainfall in Geoje reached 950 mm over the three-day holiday.”
The extreme volume of rainfall in Geoje and Tongyeong represents a significant weather event that exceeds typical seasonal norms. Because the soil was saturated over a consecutive three-day period, the risk of landslides remains critical even if current rainfall totals are lower than the holiday peak. The combination of high humidity and 33 °C temperatures may further complicate recovery efforts and public safety.
