The monsoon front will bring more than 30 mm per hour of torrential rains to Seoul and the central region on Thursday and Friday, the Korea Meteorological Administration forecast Wednesday.

A weatherman said torrential rains accompanied by thunder, lightning and gusts of wind are expected from Thursday afternoon until early Friday morning. Another spate of heavy rains could bring increased dangers of collapsing embankments and mudslides since the ground is still weak as a result of downpours last Saturday, he added.

The rain will start falling in the Jeolla provinces and the southern coastal area of South Gyeongsang Province on early Thursday morning. The monsoon front will then bring rain to most areas in the central part on Thursday morning. Most parts will see rain until Friday morning.

The central region except for eastern Gangwon Province, will have 30-80 mm of rain and over 120 mm in some parts, and the southern region, eastern Gangwon and Jeju 10-50 mm.

The seasonal rain front will start moving south on Friday, stay over the sea near Jeju, and then move north again to bring rain nationwide next week, the KMA added.
