Hokuriku Hokuriku The first half of the three-day holiday is unpredictable weather A tropical cyclone occurs in the South Sea A cold vortex approaches from the continent (Weather forecaster Takeshi Kawahara September 21, 2022)-Japan Weather Association tenki.jp

A tropical cyclone developed over the sea south of Japan at 3:00 am on the 21st. This tropical cyclone is not expected to develop as markedly as Typhoon No. 14 did the other day, but it will move north and approach Honshu from the 23rd to the beginning of the three-day weekend. It is accompanied by a large amount of warm and moist air originating from the tropics, so we need to pay attention to future trends.

On the other hand, from the continental direction, a low pressure “cold eddy” accompanied by strong cold air of -21 degrees or less is expected to gradually approach around 5500 meters above the ground. Cold air will gradually flow into the upper atmosphere, and warm and moist air will flow into the lower layers. If the warm and moist air from tropical cyclones flows in more than expected, the Hokuriku region will experience extremely unstable atmospheric conditions. It seems that there are places where active cumulonimbus clouds occur when intense rising air currents occur. There is a risk of flooding of low-lying land and roads due to sudden and strong rain, swelling and flooding of rivers and irrigation canals, landslides, and violent gusts of lightning and tornadoes.During the three consecutive holidays, especially those who plan to spend time outdoors on the 23rd or 24thlatest forecastPlease confirm.

On the 25th and 26th, the last days of the three-day weekend, the Hokuriku region is expected to be covered with high pressure from the north and clear autumn skies. There are many summer days with maximum temperatures of 25 degrees or higher, but generally the wind will blow from the north, making it easier to spend than the actual numbers.
