The water kept flowing into the living room through the floor."<br /><br />According to the Central Disaster and Safety Countermeasures Headquarters,... nearly five-hundred cases of sewer overflows were reported across Seoul as of nine p.m. on Tuesday. <br /> Major roads along the Han River were also blocked due to flood concerns.<br />Flood warnings were issued around major streams in Seoul, where heavy rain advisories were issued, including the surrounding Gyeonggi-do Province and northern Gagnwon-do Province. <br /> Authorities are urging people to watch out for possible damage as heavy rain is forecast to continue through Wednesday. <br />Kim Hyo-sun, Arirang News. <br />
