Heavy rain is pouring down incessantly in Jeju.

Strong winds with instantaneous speeds of around 10 meters per second are also blowing.

Over the past weekend, more than 100mm of rain fell on Hallasan Mountain.

While the rain was caused by a pressure trough moving eastward, the Korea Meteorological Administration (KMA) stated that it is difficult to consider this the start of the monsoon season.

[Interview] Choi Ji-young / Forecaster, Jeju Regional Meteorological Office: "Rain that falls during the monsoon season occurs when the North Pacific High expands, creating conditions conducive to heavy precipitation as warm, humid air from the south flows in."

Meanwhile, the possibility of a typhoon acting as a variable for this year's monsoon season is being raised.

Typhoon Meari, the 7th typhoon of the year, is currently moving northward from the waters near Manila, Philippines.

It is forecast to strengthen to intensity level 4, passing through the waters southeast of Taiwan and moving up toward the waters off Okinawa, Japan.

The outlook for the monsoon season is expected to change depending on the movement of the North Pacific High and the northward progression of the stationary front after the typhoon passes.

[Interview] Woo Jin-gyu / Spokesperson, Korea Meteorological Administration: "It appears that the atmospheric pressure systems around the Korean Peninsula, including the North Pacific High, will reorganize after the typhoon passes, and the outline of the monsoon season will be drawn then."

The average start date for the monsoon season in Jeju is June 19, with an average of 17.5 rainy days and 348.7mm of precipitation.
