Typhoon No. 7, known as Mekkhala, is moving toward eastern Japan and is expected to bring heavy rain and landslides tonight [1, 2].
The storm's trajectory threatens critical infrastructure and residential safety across several prefectures, prompting emergency evacuation orders and the suspension of major transit lines to prevent casualties.
As of June 27, 2024, the storm was located approximately 180 km south of Cape Muroto [2]. It is moving northeast at a speed of 50 km/h with a central pressure of 992 hPa [2].
Meteorologists forecast significant rainfall across the region. The Tokai region expects up to 200 mm of rain, while the Kanto and Koshin regions are forecast to receive 150 mm [1]. In Chiba, the city of Kimitsu recorded its highest hourly rainfall for June on record [1].
Local authorities have issued level-4 landslide warnings for Choshi city and Miura city in Kanagawa [1]. In Miura city, officials said they issued an all-area evacuation order to protect residents from potential soil collapse [1].
Transport disruptions have already begun. The Tokaido Line has suspended all-day service for both up and down lines between Odawara and Atami [1]. Additionally, certain sections of the Kenkōdō Expressway are closed due to landslides [1].
Other local services have also halted operations. Ropeways and amusement parks have closed for the night as a precaution [1].
Meanwhile, Typhoon No. 8 has transitioned to an extratropical low pressure system [1].
“The Tokai region expects up to 200 mm of rain, while the Kanto and Koshin regions are forecast to receive 150 mm.”
The convergence of high-intensity rainfall and existing soil instability in the Kanto and Tokai regions increases the risk of flash floods and mudslides. By issuing level-4 warnings and preemptive transport suspensions, Japanese authorities are attempting to minimize the risk of commuters being stranded in high-danger zones during the storm's peak impact.
