Typhoon No. 6 is expected to transition into an extratropical low on Thursday morning, June 4, 2024 [1].
The shift in the weather system brings significant rain and potential thunderstorms to the western regions of Japan, disrupting travel and outdoor activities. This transition marks the weakening of the typhoon's core as it interacts with a cold front.
TBS NEWS DIG said the system will be located over the eastern offshore sea when it becomes an extratropical low [1]. The transition is driven by the northward movement of Typhoon No. 6 and a cold front advancing from the west [2].
Kyushu is expected to experience rain starting in the morning [1]. The weather system will also impact Shikoku, as well as the Chugoku and Kansai regions [2].
Nationwide daytime temperatures are forecast to range between 24 °C and 29 °C [1]. In Tokyo, the temperature is expected to reach 24 °C, which is four °C higher than the previous Wednesday [1]. Meanwhile, Okinawa is forecast to see summer temperatures exceeding 30 °C [1].
The impact of the storm has already been felt in the education sector. A total of 5,378 schools nationwide have closed due to the effects of Typhoon No. 6 [3].
Meteorologists said that clear skies will be limited across the country as the front moves through. The combination of the weakening typhoon and the advancing front ensures that widespread moisture will persist over the Japanese archipelago throughout the day [1, 2].
“Typhoon No. 6 is expected to transition into an extratropical low on Thursday morning.”
The transition of a tropical cyclone into an extratropical low typically signifies a change in the storm's energy source, moving from warm ocean waters to temperature gradients in the atmosphere. While the system loses its symmetric typhoon structure, it can still distribute heavy precipitation over a wider area, which explains the forecast for widespread rain and thunderstorms across western and central Japan.
