South Korea is getting heavy rain this week.<br />The city of Gwangju and the surrounding Jeollanam-do Province saw flooding last night and this morning,... and there are advisories and warnings in effect elsewhere.<br />Our Kim Da-mi explains why we're getting this fall monsoon. The most recent typhoon is long gone, but heavy rain is coming down nationwide.<br /> <br /> The southwestern city of Gwangju got up to sixty-millimeters of rain an hour last night, causing drains to overflow in the city center and trees on the side of the street to fall over.<br /><br /> As of Tuesday morning, a flood advisory has been issued for the city of Daejeon, where several buildings and homes were flooded.<br />Flooded roads also made for a chaotic morning commute. <br /><br /> So what has caused this heavy rain? <br />The North Pacific Anticyclone, which had been destabilized by Typhoon Soulik, is now stable again.<br />On top of that, a tropical cyclone is sending water vapor up from the south, which meets up with cool air and causes these heavy downpours on the Korean Peninsula. <br /><br />Some have called this phenomenon a fall monsoon and the start of autumn.<br /> But experts explain that this isn't a true fall monsoon because the North Pacific Anticyclone has not disappeared yet.<br /><br />According to the Korea Meteorological Administration, the heavy rain will last until Thursday nationwide.<br /><br /> After that, the air will feel pleasantly cooler. But there will still be days when it gets above 30 degrees Celsius, and we won't get to autumn until early September.<br />Kim Da-mi, Arirang News. <br />
