May 06, 2023 08:42
Today on the 6th, the area of rain spread from the Sea of Japan side, causing heavy rain in Kyushu and Hokuriku. In areas such as Suzu City, Ishikawa Prefecture, where tremors were strong, beware of landslide disasters even with a little rain. In the inland area of Kanto, there are places where it is midsummer, so be careful of heatstroke.
Locally very heavy rain/heavy rain
Today, the 6th, a low pressure system is expected to advance near the Tsugaru Straits, and the front is expected to move southwards over Honshu. Warm, moist air like during the rainy season is flowing toward low pressure systems and fronts, making the atmosphere unstable. Looking at the rain cloud radar as of 8:00 am, we can see that rain clouds are developing in the northern part of Kyushu, south of the front, and on the Sea of Japan side of Tohoku. In Goto City, Nagasaki Prefecture, it rained heavily with an hourly rainfall of 47.0 mm (until 5:59 am).
Today, the 6th, it will continue to rain in Kyushu, and it is likely that there will be places with very heavy rain like waterfalls. The Chugoku region and Shikoku will gradually rain, and Kinki and Tokai will also start to rain widely in the evening. Locally heavy rain is expected along with thunder.
In Hokuriku, there are places where it is already raining, such as the Noto Peninsula, and the area of rain will gradually spread. Heavy rain is likely to fall at night, mainly in Ishikawa Prefecture, where an earthquake with a maximum seismic intensity of 6-upper occurred on the 5th. Avoid dangerous areas such as cliffs as the ground may be loose in areas with strong shaking.
In Kanto-Koshin, the weather is downhill, although there are places where it is sunny until around noon. At night, it will rain in some places, especially in the inland areas. It rains widely in the Tohoku region, and it is likely that there will be times when it rains strongly. The rain in Hokkaido will stop around noon, and the sun will reach the Sea of Japan side.
Heavy rain tomorrow 7 days
Expected rainfall (high areas) 24 hours until 6:00 am on the 7th
Northern Kyushu 150mm
Hokuriku/Tokai 120 mm
Depending on the trend of the low pressure that will occur in the East China Sea on the 7th tomorrow, the amount of rain will increase further. Be vigilant and careful of landslides, flooding of low-lying land, rising water levels and flooding of rivers.
In the Kanto region, there is also a midsummer day
Today’s forecast maximum temperature for the 6th.
Even if it’s cloudy or rainy in Okinawa, there are many places where the highest temperature is around 28 degrees Celsius. It seems to feel quite hot and humid. In Kyushu, the Chugoku region, and Shikoku, the temperature is about 20 to 22 degrees Celsius, about 5 degrees lower than yesterday’s 5th. However, there are places such as Takamatsu where the temperature rises above 25°C in the summer.
Kinki and Tokai will be around 25 degrees Celsius, about the same as yesterday’s 5th. In the Kanto region, the heat continues, with temperatures reaching 27°C in central Tokyo. Maebashi and Utsunomiya will be 30 degrees Celsius, and Kumagaya will be 31 degrees Celsius. Don’t overdo it, and take measures against heatstroke, such as drinking water frequently.
In the three prefectures of Hokuriku, the southerly wind blows, and there are many places where the temperature rises above 25 degrees Celsius. On the other hand, in Niigata, the temperature is 18℃, and it seems to be cool even during the day. In Tohoku, there are many places where the temperature does not reach 20℃, and it will be significantly lower than yesterday’s 5th. Hokkaido is on the north side of the front and is replaced by cold air. The wind blows from the north, so it will feel colder than the temperature. Please dress appropriately.
Premonition of landslide disaster
When a landslide disaster occurs due to heavy rain, there is a phenomenon that serves as a precursor. Please keep this in mind in case of emergency.
The first is that cracks can form in cliffs and ground.
The second is hearing the crackling of wood, the clashing of stones, and the smell of earth.
The third is that the water in wells, rivers, and springs becomes turbid. Even if the spring water stops, it is one of the harbingers.
The fourth is that water springs out from cliffs and slopes.
In addition, there are pebbles falling apart, rumbling of the ground and rumbling of the mountains, the water level of rivers dropping even though it continues to rain, and trees tilting. At times like this, the risk of landslide disasters is increasing. Call out to people around you immediately and evacuate to a safe place.
