Due to the influence of cold air and moist air in the sky, the atmospheric conditions are expected to become unstable in eastern and western Japan on the 25th, so it is necessary to be careful about heavy gusts such as lightning strikes and tornadoes, and sudden heavy rain.
According to the Japan Meteorological Agency, strong cold air will flow into the sky during this period, and warm and moist air will flow from the south near the surface of the earth. The condition is expected to become unstable.
From the afternoon of the 25th in the Chugoku region, and from the evening of the 25th in the Kanto and Hokuriku regions, we are calling for attention to heavy gusts such as lightning strikes and tornadoes, sudden heavy rains, and "hail".
If there are signs that a developed cumulonimbus cloud is approaching, such as when the surroundings suddenly become dark and a cold wind blows, move to a sturdy building to ensure safety.
On the other hand, since yellow sand was observed on the Korean Peninsula on the 24th, it is possible that yellow sand will fly over a wide area centered on western Japan on the 25th.
The "visibility" of what is clearly visible to the naked eye is less than 10 kilometers, and in some cases can be less than 5 kilometers.
The Japan Meteorological Agency says that if the visibility is less than 5 km, it may hinder traffic, and is calling for caution when driving a car or adhering yellow sand to laundry etc. in poor visibility. ..
