SEOUL, June 11 (AJP) - This summer's first monsoon rains will drench the country later this week, starting with the southern resort island of Jeju, which is expected to see up to 40 mm of precipitation, the Korea Meteorological Administration said Wednesday.

According to the KMA, the monsoon rain front currently hovering near Japan will move north as a North Pacific high-pressure system approaches, bringing heavy rainfall to Jeju Island on Thursday before spreading to other southern and central regions over the weekend.

This year's rainy season arrives about a week earlier than usual, as the monsoon usually begins in mid-June on the Korean Peninsula. But it remains to be seen whether the entire country will soon come under the full influence of the monsoon front.

Many meteorologists forecast a wetter summer ahead, as an unusually strong North Pacific high-pressure system is likely to cause more frequent and unpredictable torrential downpours.

A KMA official warned, "In recent years, extreme downpours have occurred even after the monsoon season ends, so it is advised to stay prepared for heavy rainfall that may persist through August and beyond."
