We're over 300mm now for the last 24hrs, most of that in the last 12hrs or less.

This is going to be in news later today and tomorrow.
 
It may be cycling on by, but earlier the level for "total precipitation in the last 24hrs" was 331.5, and that just happens to be at the recording station--some places in the area could have exceeded that.

Yes, it has stopped, and the seven-day says a couple days of clear and sunny, followed by rain (hopefully not like last night and early this morning. I'm sure there'll be pics in the morning paper, I'll try to post those tomorrow.

Went to a supermarket after lunch today, and specifically to one that had an underpass on the way (local line, not shinkansen). It was very much blocked by signage and guards, tho I couldn't see any water. Small detour, a hundred meters or so to one side, then across the tracks at a level crossing, then back on course.
 
Bikes are of course dry, but the afternoon, if it hadn't again hit a 32+ high, would have been bike-able.

In other wx news:


whoa, a waterspout. Thankfully they are generally less dangerous than tornadoes, especially if they fail to make landfall. I guess there's no specific Japanese word for it aside from 竜巻...
 
I wouldn't want to be out there in any kind of boat testing that theory!
there are actually two kinds of waterspouts, tornadic and non-tornadic. The former is associated with more severe weather patterns and has more destructive power, but still less compared to a landed tornado. But yeah either way I prefer to admire from afar
 
It is also raining heavily now in Kyushu .
Record-Breaking Rain in Kagoshima — Flood Damage Leaves Longtime Residents Homeless
(Super J Channel, August 9, 2025)

On August 8, Kagoshima Prefecture was hit by record-breaking rainfall, causing houses to collapse and leaving one woman missing. By the morning of the 9th, the area affected by the rain had expanded.
Flood Damage — A Longtime Home Lost
On the 9th, some parts of Kyushu experienced the heaviest rainfall of the year.
In Nagasaki City, as much as 48.0 mm of rain fell in a single hour. The river water turned a muddy brown, and rainwater was seen cascading rapidly down stairways.
Kagoshima Prefecture experienced particularly severe rainfall. A linear rainband formed, causing extensive damage in various areas.
In Kirishima City, Kagoshima, houses suffered flood damage, with water levels reaching above floor level.
On August 8, the nearby Amorigawa River overflowed, sending water surging into residential areas.
Resident: "(Q: Did the water come up to here?) I suppose so — I had already evacuated."
The home she had lived in for many years was left covered in mud.
Resident: "(Q: How long had you lived here?) About 60 years. I don't think I can live here anymore."
(Q: You mean you can't live here again?) "I don't think so."
The damage also reached a hot spring town associated with Saigō Takamori .
Inn employee: "You can see the mark. The water came up to nearly two meters."
Photos from that time show floodwaters reaching just below the inn's signboard.
Although the water later receded, the damage was devastating.
Inn employee: "We've drained the baths, but the pipes are probably clogged with mud and nothing flows."
Mud had poured into the bathing areas, and staff were still struggling to grasp the extent of the damage.
Inn employee: "Hmm… there's really nothing we can do. I'm at a loss for words that it turned out this way."
Transportation was also affected.
According to JR Kyushu, some local train services have been suspended.
In Aira City, Kagoshima Prefecture, a hillside collapsed, sending earth and debris into homes.
Police and firefighters are continuing desperate rescue operations.
Two women were rescued from one house, but a woman in her 30s remains missing.
 
From the news I've seen, it is far worse in Kagoshima & across southern Kyushu.
 
And now, northern Kyushu, including Fukuoka, is in the midst of thunderstorms.
The drop in temperature is welcome, but it's a pity that during this rare three-day holiday I can't go anywhere. I had planned to visit Hirado in Nagasaki to enjoy some seafood.

[Torrential Rain in Fukuoka Prefecture] Possible Reappearance of a "Linear Rainband" in Northern Kyushu
Due to the influence of an active stationary front, a "linear rainband" formed from late at night on the 9th to the early hours of the 10th in Fukuoka Prefecture. In northern Kyushu, there is a risk that another "linear rainband" will form through the morning of the 11th.

From late on the night of the 9th to the early hours of the 10th, it is believed that torrential rain of 110 to 120 millimeters per hour fell in areas near Fukutsu City and Shingu Town. In the Fukuoka and Kitakyushu regions, a "linear rainband" caused extremely heavy rainfall to persist over the same locations.

In northern Kyushu, the risk of disasters may increase sharply if another linear rainband forms through the morning of the 11th.
In the 24-hour period through the morning of the 11th, rainfall is expected to reach up to 300 millimeters in parts of Fukuoka Prefecture.

Strict vigilance remains necessary for landslides, flooding in low-lying areas, and river overflows.
