Typhoon No. 5 'Songda' to Affect Jeju and South Coast This Weekend: "Strong Winds and Heavy Rain on the Afternoon of the 30th"

Tropical Depression No. 10 to Develop into Typhoon 'Songda' within 24 Hours
Beware of Swell Waves on Jeju and Southern Coast from 29th to 1st
Heavy Rain Expected on Jeju and Southern Coast from Afternoon of 30th

[Asia Economy Reporter Han Jinju] Tropical depression No. 10 is expected to develop into the 5th typhoon 'Songda' on the 29th and affect the Jeju and southern coastal areas over the weekend.

On the 28th, the Korea Meteorological Administration held an unscheduled briefing to announce the current status and forecast of tropical depression No. 10. As of 9 a.m., the tropical depression had a central pressure of 1002 hPa and was moving west-northwest at 23 km/h about 870 km northwest of Guam. The sea surface temperature along the tropical depression's path is between 29 and 30 degrees Celsius, creating favorable conditions for typhoon development.

Forecaster Lee Kwang-yeon explained, "The tropical depression is expected to develop into the 5th typhoon Songda around 9 a.m. on the 29th, pass south of Kyushu, Japan on the 30th, cross the southern offshore waters of Jeju on the 31st, and make landfall near Shanghai, China on the 1st."

As the typhoon moves northward, heavy rain accompanied by strong winds will fall mainly on Jeju and the southern coast starting from the afternoon of the 30th. High waves and swells are expected in the offshore waters of Jeju and the southern sea between the 29th and the 1st. There is a possibility that typhoon warnings will be issued for the southern offshore waters of Jeju and the eastern offshore waters of the southern sea. Special caution is advised for those planning camping or marine sports during the vacation season.

Forecaster Lee added, "As the tropical depression moves northward, it will push the warm and humid air mass located over the Pacific Ocean toward the Korean Peninsula, resulting in heavy rain from the afternoon of the 30th in Jeju and the southern coastal areas, where the topographical effect is enhanced. Due to the warm and humid air, inland areas will experience intensified heat and tropical nights."

The typhoon is expected to reach its peak strength on the morning of the 30th, passing south of Kyushu, Japan, with a central pressure of 994 hPa, then weaken as it moves toward the southern offshore waters of Jeju and the offshore waters near Shanghai, China. It is expected to degrade into a tropical depression by the 2nd.

There is significant variability in the typhoon's path and development. A key factor influencing the tropical depression's route is the low-pressure circulation located over the Philippine Sea. Within this large low-pressure circulation, there are three similarly sized low-pressure circulations, and their interactions can cause variability. These low-pressure circulations share the warm and humid air that serves as the typhoon's energy source, and depending on their strength, they can either promote typhoon development or inhibit its intensification.

Forecaster Lee explained, "During the northward movement of this tropical depression toward our country, it may be affected by increased circulation variability over the Philippine Sea. There is also a possibility that the path may shift further south. While the high sea surface temperature in the lower layers supports the tropical depression, the intensity, timing, and degree of dry air intrusion into the tropical depression can cause significant variability in its development."
