The 17th Typhoon Nanka is expected to move toward the waters east of Japan, reducing the likelihood of direct impact on the Korean Peninsula. However, the weather in Korea around the Liberation Day holiday may change depending on the typhoon's path and the position of the North Pacific High, drawing attention to its future trajectory.
Previously, the 15th Typhoon Chanhom weakened to a tropical depression after passing through the Japanese archipelago on August 12. Although it did not directly hit the Korean Peninsula, Chanhom's influence brought in easterly winds, resulting in rain, strong winds, and high waves along the eastern coast.
Typhoon Nanka formed near the Ogasawara Islands on the morning of August 12 and, as of 3 a.m. on August 13, was moving northward near the islands. Japanese meteorological data suggests that Nanka will move northeast before heading toward the waters east of Japan.
Current projections indicate that Nanka is unlikely to make landfall on the Korean Peninsula or pass directly through it. Domestic reports forecast that Nanka will travel over waters more than 1,800 kilometers away from Korea.
However, it is premature to conclude that there will be no impact on the Korean Peninsula. Japanese meteorological outlets report that while Nanka is expected to move toward the eastern waters, uncertainty in its trajectory may increase after the weekend. The direction of the typhoon could change depending on the position of the high pressure located east of Japan.
According to the Korea Meteorological Administration (KMA), the most significant variable for the Korean Peninsula is not the direct impact of Nanka but the heat and rain expected after the Liberation Day holiday.
The KMA's medium-term forecast, released on August 13, predicts rain across the country on August 17. Expected temperatures on that day are 24-30 degrees Celsius in Seoul, 24-31 degrees in Daejeon, 25-31 degrees in Gwangju, and 26-29 degrees in Busan.
In contrast, the heat is expected to continue until the rain arrives. The KMA anticipates morning temperatures between 22-26 degrees and daytime highs of 29-34 degrees, which are above average for this time of year. Notably, the perceived temperature in most regions may exceed 33 degrees, indicating a prolonged heat wave.
Thus, during this Liberation Day holiday, preparations should focus on localized rain amid the heat rather than a direct hit from Nanka, along with the potential for nationwide rainfall after the holiday.
The KMA also noted that the weather on August 17 could be influenced by changes in the position of the North Pacific High and the occurrence and movement of tropical disturbances, indicating that the timing and areas of rainfall may vary.
Ultimately, while the current forecast suggests a low likelihood of direct impact from Nanka on the Korean Peninsula, the typhoon's influence on surrounding pressure systems could affect the timing and intensity of rain after the holiday. Therefore, it is crucial to monitor the latest rainfall forecasts and heat information leading up to Liberation Day.
