Autumn skies will continue in many places until the 14th (Saturday), but the mornings and evenings will be cold. Especially on Saturday the 14th, the temperature difference between morning and evening and daytime is likely to be large, especially in Hokkaido and Tohoku. The Ogasawara Islands have been in a state of emergency since the night of the 12th (Thursday) as Typhoon No. 15 approaches. We need to be careful of high waves until the 14th (Saturday).
12th (Thursday) – 18th (Wednesday)
Tomorrow, the 12th (Thursday) and 13th (Friday), the area around Honshu will be covered in high pressure, and autumn skies will continue over a wide area. However, there are likely to be some showers around the Kanto region on the night of the 12th (Thursday).
Although it will be sunny in many places on Saturday the 14th, clouds will begin to spread over western Japan due to the influence of a trough in atmospheric pressure. There will be some rain on the 15th (Sunday), mainly on the Pacific side of Honshu.
A low pressure system and front will pass through northern Japan from the 16th (Monday) to the 17th (Tuesday). Clouds are likely to spread over Hokuriku, Tohoku, and Hokkaido, and there are likely to be some places where it will rain. It is also possible that the weather will be rough, especially along the Sea of Japan side.
Temperatures during this period will be around normal or higher than normal, and in Hokkaido in particular, the maximum temperature from the 13th (Friday) to the 15th (Sunday) is likely to be significantly higher than normal in some places.
On the sunny morning of the 14th (Saturday), radiation cooling will intensify and many places will become colder, while temperatures will rise during the day. The temperature difference between morning and evening and daytime will be large, especially in Hokkaido and Tohoku, and in some places the temperature difference will be more than 15℃. Please be careful when choosing clothing.
The Ogasawara Islands will be closed from the night of the 12th (Thursday).
As of 9 a.m. on the 11th (Wednesday), Typhoon No. 15, a large and extremely strong typhoon, is located in the Mariana Islands and is moving north-northwest at a speed of approximately 20 kilometers per hour. After this, it will continue to move north as it continues to develop, and on the 12th (Thursday) it is expected to become a “fierce” force and move toward the waters near Ogasawara.
In the Ogasawara Islands, the wind gradually becomes stronger and the waves become higher. Strong winds will blow from the followingnoon of the 12th (Thursday), and there will be heavy swells at night. The expected maximum wind speed (maximum instantaneous wind speed) is 18 meters (30 meters), and the expected wave height is 6 meters, with swells.
On the 13th (Friday), there will be very strong winds and there will be some places with torrential rain. Conditions at sea will continue to be rough. It is necessary to be cautious of high waves until around the 14th (Saturday). Expected maximum wind speeds (maximum instantaneous wind speeds) will be 20 to 24 meters (25 to 35 meters), and expected wave heights will be 6 to 8 meters, with swells.
19th (Thursday) – 24th (Tuesday)
From the second half of next week onwards, there will be some temporary rain, but there will be many sunny days. Temperatures are expected to be higher from Hokkaido to the Kanto region next weekend, with many places in the Kanto region likely to experience summer days with maximum temperatures of 25℃ or higher.
So far, it won’t be extremely cold next week, but the mornings and evenings are likely to get colder day by day. From Kanto to Kyushu, you can wear light clothes during the day, but you may want to wear a lined trench coat in the morning and evening. It’s a good idea to have them ready in a place where you can easily take them out early so that you can put them on quickly even if it suddenly gets cold.
