Typhoon Nakri fizzled into a tropical rainstorm on Sunday afternoon but is bringing nationwide rain on Monday.
Nakri, named after a Cambodian flower, poured more than 1,500 mm of rain in mountainous parts of Jeju Island over the weekend, a new record for the southern resort island. Jeju saw 1,182 mm of rain on Saturday alone, which is equivalent to the total precipitation of 1,200 to 1,400 mm the peninsula sees in a year. Farms and roads were inundated in most southern parts of the mainland as well.
Rain will come to a stop on Monday as the storm moves on, but a much more powerful typhoon is heading north and the Korean Peninsula will come under its influence on Friday.
Typhoon Halong began forming on July 29, earlier than Nakri, but is taking longer to approach Korea as it originated east of Guam and is moving north slowly.
Halong is named after a major tourist attraction in Vietnam. It developed into a super typhoon on Sunday afternoon with a central pressure of 915 hPa and a maximum wind speed of 54 m/s.
The intensity of the typhoon is expected to remain strong until Friday, when it begins to affect Jeju.
Kim Kyung-lip at the Korea Meteorological Administration said, "It's uncertain whether this typhoon will head straight toward Korea or shift direction toward Japan."
Meanwhile, Korea will remain vulnerable to typhoons until October, with conditions especially ripe this year because the El Niño phenomenon has raised ocean temperatures along the equator. According to meteorologists, this could lead to more frequent and powerful typhoons.
