The most powerful typhoon to hit South Korea in years killed at least six people, dumped a meter of rain, destroyed roads and felled power lines on Tuesday. The death toll could have been higher if not for proactive evacuations and school closures, officials said. There was also greater public awareness about the storm and its risks. Typhoon Hinnamnor made impact just weeks after heavy rain around the capital, Seoul, caused flooding that killed at least 14 people. Government officials put the nation on high alert for days as Hinnamnor approached, warning of potentially historic destruction and putting in motion life-saving measures. After grazing the resort island of Jeju and hitting the mainland near the port city of Busan, Hinnamnor weakened as it blew into waters between the Korean Peninsula and Japan.
