Heavy rain following intense heat in Hokuriku, strong warmth and humidity from the tropics influencing front activity?
Heavy rain following intense heat in Hokuriku?
July 16, 2023 at 18:48
In the Hokuriku region, due to the Foehn phenomenon and strong sunshine, the heat has become severe over a wide area, and there are many places where extremely hot days have been observed. On the 17th (Mon/holiday), the heat wave is expected to continue in Toyama, Kanazawa, and Fukui. On the other hand, at the beginning of the week, the strength of the Pacific anticyclone will gradually weaken, and especially on the 19th (Wednesday) the front will move southward over the Hokuriku region. Currently, the clouds that developed east of the Philippines are gathering and moving northward. There is also a risk that this will flow into the Hokuriku region and intensify frontline activity. Please pay attention to the latest information.
Due to the foehn phenomenon and intense sunlight, the hottest heat of the year will continue on the 17th, so beware of heatstroke
Today, the 16th (Sunday), the temperature in the Hokuriku region has risen sharply, with 36.9 degrees in Toyama and 36.0 degrees in Fukui, making it the hottest point of the year at 23 locations, mainly in the three prefectures of Hokuriku.
Today, the force of the Pacific anticyclone gradually strengthened over the seas south of Japan, and the strong sun shone down on the three prefectures of Hokuriku. On the other hand, the seasonal rain front remained stationary from the Sea of Japan to the Tohoku region, and the southerly winds blew toward the front.
Tomorrow, the 17th (Monday/holiday), the strength of the Pacific high will increase further. It looks like the foehn phenomenon will disappear, but the strong sunlight will shine from the morning, and the intense heat will continue. The forecast maximum temperature for tomorrow, the 17th (Monday/holiday) is 35°C in Toyama, Kanazawa and Fukui, and it will continue to be extremely hot. Even in Niigata Prefecture, it will be extremely hot, with temperatures reaching 34 degrees in Takada and 32 degrees in Niigata.
Severe heat is likely to continue until the 18th (Tuesday). This is the time when the body is not yet accustomed to the heat, so the risk of heat stroke is high. Be sure to keep hydrated frequently, use air conditioning appropriately, and take frequent breaks when working outside.
After the heat, there is a risk of heavy rain Strong warm and humid weather from the tropics may intensify frontal activity
After the 18th (Tuesday), the strength of the Pacific High will weaken rapidly. On the 18th, the front will gradually become clearer in the Sea of Japan, gradually move southward, and is expected to move southward in the Hokuriku region on the 19th (Wednesday).
Also, the clouds that have now developed east of the Philippines are clustered together. This is a mass of clouds in the stage before becoming a tropical cyclone or a typhoon. This cloud area will move north around the edge of the Pacific high and flow into the Sea of Japan from the East China Sea via the southern part of the Korean Peninsula. So far, there is no forecast that it will develop into a typhoon or tropical cyclone, but there is a risk that it will flow toward the front as strong warm and humid air originating from the tropics, increasing the activity of the front.
In the Hokuriku region, on the 19th (Wednesday), it is necessary to pay attention to short-term heavy rain, lightning strikes, and gusts. Depending on the movement of warm and moist air, rain clouds may develop rapidly, and there is a risk of heavy rainfall warning levels. Also, there are places where the ground is loose due to the heavy rain caused by the linear rain belt the other day, so please be careful and be vigilant once morest landslide disasters.
Typhoon season is coming El Nino phenomenon may increase the number of approaches in midsummer
The number of typhoons is highest in August, followed by September. The typhoon moves along the edge of the Pacific High. Every year, the force of the Pacific anticyclone is strong in August, and typhoons often move toward the continent, so the peak of the typhoon season near Japan is in September.
On the other hand, due to the El Niño phenomenon this year, the Pacific High is expected to extend weakly toward the vicinity of Japan. . In addition, typhoons such as Typhoon No. 21 in 2017 and the East Japan Typhoon in 2019 have also caused serious damage in October. Think of the typhoon season from now until around October, and be fully prepared.
