TOKYO - Tokyo is expected to record a high of 22°C on October 1st, marking the first time in 112 days since June 11th that the temperature has fallen below 25°C, with rainfall cooling the air and bringing an end to the long stretch of summer-like days.
Moist air flowing in at ground level and cold air moving in aloft are causing unstable atmospheric conditions over Kanto, Hokuriku, Tohoku, and Hokkaido, where thunderstorms and heavy rainfall are forecast. Under thunderclouds, tornadoes and sudden gusts of wind may also occur, and residents are urged to stay inside sturdy buildings when thunderstorms strike.
By noon on October 2nd, forecast rainfall amounts are expected to reach up to 180 millimeters in Hokkaido, 100 millimeters in Tohoku, 80 millimeters in Kanto-Koshin, and 60 millimeters in Hokuriku. Parts of Hokkaido’s Iburi region have already recorded more than 300 millimeters of rain in just six hours, raising the risk of landslides and river flooding as rain continues to fall.
In contrast, western Japan will see clear skies and abundant sunshine, with temperatures likely to exceed 30°C in many locations, creating midsummer-like conditions.
Meanwhile, typhoon season continues in the southern seas, with a tropical depression east of the Philippines expected to develop into Typhoon No. 21 by October 2nd. However, with a strong Pacific high-pressure system over southern Japan, the storm is not expected to approach the country.
