Typhoon 7 is moving west or north while intensifying over the waters east of the Philippines [1, 2].
Although the storm is not expected to make direct landfall in Japan, its movement is shifting atmospheric patterns. The system is pushing moist air into the rainy season front, which creates a significant risk of heavy precipitation for the northern Tohoku region [1, 2].
Authorities said the official start of the rainy season for northern Tohoku was June 21, 2024 [2]. This timing coincides with the typhoon's influence, increasing the likelihood of torrential rains that could lead to localized flooding or landslides in the region [1, 2].
Weather forecasts for the day show a wide range of temperatures across the archipelago. In the north, Sapporo is expected to reach a high of 25 degrees Celsius [1], while Kushiro will see a cooler high of 15 degrees Celsius [1]. Aomori, Morioka, and Sendai are forecasted at 21 [1], 20 [1], and 20 degrees Celsius [1], respectively.
Central and southern regions will experience significantly warmer conditions. Niigata is expected to hit 24 degrees Celsius [1] and Nagano 31 degrees Celsius [1]. Nagoya and Kochi are forecasted to be the warmest cities, both reaching 33 degrees Celsius [1].
Other major cities include Tokyo at 27 degrees Celsius [1], Osaka at 30 degrees Celsius [1], and Kanazawa at 27 degrees Celsius [1]. In the west, Okayama and Hiroshima are both expected to reach 29 degrees Celsius [1], while Matsue is forecasted at 25 degrees Celsius [1].
Meteorologists said the storm will continue to develop as it progresses. While the direct path of Typhoon 7 avoids the Japanese mainland, the indirect interaction with the stationary front remains the primary concern for residents in northern Japan [1, 2].
“Typhoon 7 is moving west or north while intensifying over the waters east of the Philippines.”
The interaction between a distant tropical cyclone and a local seasonal front demonstrates how typhoons can impact weather patterns far beyond their immediate wind field. By fueling the rainy season front with tropical moisture, Typhoon 7 increases the risk of extreme weather in northern Japan even without a direct hit, necessitating heightened vigilance for flood-prone areas in Tohoku.
