The first day I cancelled my evening appointment and hurried home to avoid the pelting rain. The next day I was on the highways of outskirt Seoul, while the city fell deeper and deeper into water. Worst rain in 100 years, they're saying.
The Sadang area where I was waiting for the bus in the video clip turned into this the very next day:
Subway stations are flooding, cars are underwater.
Landslides are happening, causing many casualties. This is in Daejeon; it's not only Seoul, the whole nation is under a storm cloud.
The extent of the damages are staggering. This photo says it all:
Flood warnings are still effective nationwide as I write. The National Emergency Management Agency has safety guidelines on their site for emergencies like this (English version) :
Among all the guidelines, I'd like to emphasize: "Avoid going near street lights, traffic signal lights, and power lines." And even if it means going a long way 'round, try not to wade in water even if the water is shallow. You never know where an electric current may be.
All the major TV channels are broadcasting special weather reports all day. Be sure to tune in and be safe.
