As we enter September, the mornings and evenings are turning noticeably cooler. The atmospheric pressure patterns surrounding the Korean Peninsula are shifting, bringing changes to the weather. However, residents along the southern coast and Jeju Island need to stay alert for potential damage from strong winds.
Reporter Jeong Gu-hui has the details.

This is Typhoon Krovan, the 24th typhoon of the season, moving northward from the waters east of Okinawa, Japan.
Winds near its center are blowing at 23 meters per second, but its intensity is classified as Level 1, the weakest among the five-tier typhoon intensity scale.
However, the typhoon is expected to linger in place for the time being, unable to head toward South Korea, the Japanese mainland, or China.
The typhoon is projected to move north tomorrow (the 4th) to waters 510 kilometers away from Jeju Island before turning back south to hover around the waters near Okinawa, Japan.
Because strong westerlies are blowing in the upper atmosphere over South Korea, typhoons typically ride these westerlies eastward. However, the North Pacific high-pressure system is positioned to the east of the typhoon, blocking its path and preventing it from moving anywhere, causing it to stall in place.
The North Pacific high-pressure system, which brought scorching heat and a secondary monsoon season to South Korea, has now shifted down toward Japan. Taking advantage of that gap, another high-pressure system has settled over South Korea.
As relatively cool northeasterly winds flow along the edge of this clockwise-rotating high-pressure system, autumn weather is setting in, with morning temperatures dropping to around 20°C in Seoul and other central regions.
A high-pressure system is positioned to the north, while a low-pressure typhoon sits to the south. This northern-high and southern-low pressure pattern is expected to persist for the time being.
This setup causes the clockwise rotation of the high-pressure system and the counterclockwise rotation of the low-pressure system to interact, generating strong easterly winds at the surface.
As a result, very strong winds are expected to blow mainly around the southern coast and Jeju Island through the weekend, and frequent rain is forecast for Jeju Island.
Because strong winds may disrupt flight and vessel operations, travelers should check real-time transportation schedules.
Gangwon Yeongdong region experienced rain today due to the influence of easterly winds, and rain along the east coast will continue through the weekend.
