Hokuriku Fehn is the hottest typhoon in Japan Typhoon No. 6 is going east and north and is the Sea of Japan course 1 month forecast
August 03, 2023 at 18:28
The temperature rose in the Hokuriku region on the 3rd due to the Foehn phenomenon, and in Komatsu it was 39 degrees Celsius, the highest temperature in Japan today. In addition, there is a possibility that Typhoon No. 6, which is worrisome, will move eastward in the direction of western Japan and then move northward into the Sea of Japan. In that case, there is a possibility of further temperature rise. Depending on the future course of the typhoon, the forecast following the 7th of the week may change significantly, so please check the latest forecast.
On the 3rd, “Komatsu’s No. 1 39°C in Japan” Dangerous heat exceeding body temperature due to the Foehn phenomenon
In the Hokuriku region today on the 3rd, the sunshine hours were long and the strong sunlight was shining from the morning. In addition, due to the influence of Typhoon No. 6 and the front extending north of Hokkaido, winds generally tended to blow from the south to the west, causing the Foehn phenomenon, in which the temperature of the airflow over the mountains rises on the leeward side.
For this reason, Komatsu (Ishikawa) recorded 39 degrees Celsius, the highest in Japan today, Mikuni (Fukui) with 38.3 degrees Celsius, Toyama with 38.2 degrees Celsius, and Niitsu (Niigata) with 37.6 degrees Celsius. It’s been a dangerous heat that exceeds the body temperature that will be the best this season.
*The highest temperature in Toyama was observed at 11:54 before noon, but the sea breeze changed from the north in the followingnoon.
Hokuriku Most of the highest temperatures in the past were in August
Looking at the record of the maximum temperature at each observation point in the Hokuriku region until 2022, it was confirmed that there were multiple observation points of 40 degrees or more, mainly in Niigata Prefecture. Among them, Nakajo and Sanjo have been extremely hot, with temperatures exceeding 40 degrees Celsius for three consecutive years in 2018, 2019, and 2020. Both points were observed on the same day, August 23, 2018, August 15, 2019, and September 3, 2020, respectively.
Most of these dangerously hot temperatures above body temperature have been observed in August. In July in the Hokuriku region, the three prefectures of Fukui, Ishikawa, and Toyama in the western part of the Hokuriku region experienced record-breaking heat, with monthly average temperatures all ranking second following 2018. It seems that the dangerous heat will continue following this. Please take all possible measures once morest heat stroke.
One-month forecast The first half of the period is expected to have a maximum temperature of 40 degrees Celsius and a minimum temperature of 30 degrees Celsius.
On August 3, the Niigata Local Meteorological Observatory announced the “Weather Outlook for the Hokuriku Region for the Next Month” for the four prefectures of Fukui, Ishikawa, and Toyama in the western part of the Hokuriku region and Niigata in the eastern part of the Hokuriku region.
According to this, warm air is likely to flow in, so the temperature in the next month is expected to be high, especially in the first half of the period.
In the future, there will be many extremely hot days with a maximum temperature of 35°C or higher and tropical nights with a minimum temperature of 25°C or higher, and days with a high risk of heat stroke are expected to continue. If you have no choice but to work outdoors, take measures such as drinking water and salt frequently, working with multiple people as much as possible, and talking to each other regularly to prevent heat stroke and manage your health. Also, please pay close attention to the temperature control of crops and livestock.
Typhoon No. 6 will make a U-turn eastward around the 5th, and will gradually change its course to the north following the 7th.
As of 17:00 on the 3rd, Typhoon No. 6 is large and has developed into a very strong force. The central pressure is 940hPa, and the maximum wind speed near the center is 45m/s. The typhoon is expected to stagnate in the same place until tomorrow, Friday 4th, and then slowly make a U-turn to the east. After that, around the 7th (Monday), there was a possibility that it would gradually change its course to the north. Please pay attention to future typhoon information.
Trends in the Pacific high pressure in the sky, which holds the key to “typhoon course” and “heat”
The pink area shown on the weekly weather chart indicates the expected range of the Pacific High above. In general, it is said that developed low-pressure areas such as typhoons are difficult to advance in this area of the Pacific high.
Until around the 6th, the well-developed low-pressure area is likely to slowly move east along the edge of the Pacific high above.
After that, the Pacific High over this area is expected to gradually expand to the west near Honshu. For this reason, following the 7th, the developed low-pressure area was blocked from moving eastward, and there was a possibility that it would change its course toward the north along the edge of the high-pressure area. If this happens, the developed low-pressure area may take a course that cuts across western Japan and exits into the Sea of Japan.
Severe heat continues across the country, but when the developed low-pressure zone escapes into the Sea of Japan, it will become even hotter due to the Foehn phenomenon. Dangerous heat is already continuing, but it seems that further health management and temperature control of crops will be required.
On the other hand, if the Pacific high over the Honshu region does not expand westward as expected following the 7th, it is possible that the developed low-pressure area will continue eastward on the Pacific side. In this case, further extreme high temperatures due to the foehn phenomenon may be avoided.
It seems that many people travel long distances during the summer vacation. The forecast from the 7th (Monday) at the beginning of the week will change greatly depending on the course of the typhoon, so please always check the latest forecast.
