Surprise flood on Imjin River

About six months ago was International Trans-boundary Water Day. I contributed a post about using radar to track rain in North Korea to judge Imjin River water levels - most of the river is north of the DMZ.

Apparently, there was a surprise flood there this morning causing six missing on this side of the border.

The same content in English. I also see that six weeks ago, there was concern of flooding in North Korea because "Seasonal floods are common in North Korea where decades of deforestation have left the country without a natural protection of tree cover."
