On the 26th, due to the influence of low pressure, a very strong wind will blow from Hokkaido to Kyushu, and there is a possibility that it will rain very heavily mainly in western Japan.

Be wary of storms, high waves, and low land inundation.

According to the Meteorological Agency, on the 25th it was sunny and covered with high pressure nationwide, and the maximum temperature was 25.4 degrees Celsius in Hita City, Oita Prefecture, which was a summer day, but on the 26th the high pressure moved to the east and two lows from the west. It is expected to be rough as the atmospheric pressure approaches.

Risk of extremely heavy rain, especially in western Japan

It's a rain outlook.



Warm and moist air flows toward low pressure systems and fronts, resulting in unstable atmospheric conditions, and in western Japan, there is a risk of extremely heavy rainfall of 50 mm or more per hour locally.



The amount of rain expected to fall in the 24 hours until the evening of the 26th is expected to be 200 mm in Shikoku and southern Kyushu, and 150 mm in northern Kyushu including Yamaguchi Prefecture and Amami.



Be wary of low land inundation, sudden river flooding, and landslides.



In areas with a lot of snow, it is necessary to pay close attention to avalanches and inundation caused by the progress of snow melting.

Be wary of storms around the world

Also, be wary of storms over a wide area.



Due to the development of a low pressure system traveling in the Sea of ​​Japan, a very strong southerly wind is expected to blow.



The maximum wind speed expected on the 26th is 23 meters in Hokuriku including Chugoku region, Kinki and Niigata prefectures, and 20 meters in northern Kyushu including Yamaguchi prefecture, Tohoku and Hokkaido.



The maximum instantaneous wind speed on land is expected to be 30 to 35 meters, and there is a risk that the wind blowing down from the mountains will strengthen locally on the Sea of ​​Japan side.



It is expected to go off the sea, and there is a risk that the storm will continue for 27 days in Hokkaido.



The wind is particularly strong in northern Kyushu, including Yamaguchi Prefecture, from dawn to early morning on the 26th, in Kinki from morning to evening, in the Chugoku region from early to evening, in Hokuriku from early to night, and in Tohoku from early afternoon to late night. In Hokkaido, it is expected to be from the evening of the 26th to the morning of the 27th.



Be wary of storms and high waves and be prepared before the wind gets stronger.

It can also be damaged by the "spring storm"

The stormy weather from March to May is called "Maystorm" or "Spring Storm" and can cause damage.



A cyclone develops when the cold air in the north and the warm air in the south collide with each other, but in the vicinity of Japan, the temperature difference increases from March to May, so a cyclone tends to develop.



In April 2012, the maximum instantaneous wind speed was 43.5 meters in Ryotsuminato, Sado City, Niigata Prefecture, 38.9 meters in Hachioji City, Tokyo, and 28.6 meters in Osaka City.



In addition to the collapse of the warehouse, many people were killed or injured due to the fall.

What to watch out for in a storm

In areas where storms are expected, take measures such as storing things that are easily blown by the wind indoors before the wind becomes strong.



Depending on the strength of the wind, even light objects such as sandals may break the window glass, turning things around you into weapons.



If you are outdoors, you may be hit by the wind and fall and get injured.



It is also effective to review your schedule so that you do not have to go out as much as possible during the windy hours.



Also, in areas where snow remains, such as northern Japan and Hokuriku, the snow melts rapidly, so be prepared for avalanches and flood damage caused by flooding of rivers.
