Heavy rain reaches 344 mm in Yeonggwang: safety checks for Honam, Chungcheong and nearby regions

What to watch
The most dangerous thought during heavy rain is “I can make it just a little farther.” Once water reaches about half the height of a vehicle’s wheels, braking and steering can become unstable. Underpasses, semi-basements and riverside paths can fill rapidly. Around slopes or retaining walls, soil may collapse even after the rain stops, so public restrictions and local government instructions should come first.
