Hokkaido Experiences Record Heavy Rainfall

Hokkaido has been experiencing heavy rain since last night, with nearly 200mm of rain falling in just 12 hours in Edanbetsu, Asahikawa City, setting a new record. Other areas in the Urayus River basin are also experiencing record rainfall.

Although the peak of the rainfall has passed, river water levels may continue to rise, so even if you are concerned about the situation, please do not go to check the river.

The risk of landslides is also increasing. Those living in areas near cliffs and rivers where landslides may occur should evacuate early and pay attention to evacuation advisories issued by local governments.

Continuous Rain Even After Special Warning Changed to General Warning

In Hiroshima City, a heavy rain special warning was issued yesterday, July 13, but has since been changed to a general warning. Although the warning has changed, intermittent heavy rain continues.

Even after the rain stops, high water levels are expected to continue for several hours to a few days, so please do not go check the situation. Additionally, due to insufficient drainage in tributary rivers, there is a risk of swelling and flooding even away from the main rivers.

Throughout Hiroshima Prefecture, vigilance against heavy rain is necessary today. Tomorrow is expected to see a temporary lull, but intermittent rain is forecast to continue into early next week.

Even After Rain Weakens, Slopes and Rivers Remain Dangerous

In the vicinity of Yamaguchi City, intense rain fell intermittently from around 6 PM to 10 PM on Wednesday.

Rain has already passed its peak, but river water levels may rise further, so even if you are concerned about the situation, please do not check the river.

The risk of landslides is also increasing. Those living in areas near cliffs and rivers where landslides may occur should evacuate early and pay attention to evacuation advisories issued by local governments.

Continued Heavy Rain Due to a Linear Precipitation Zone

In Oita Prefecture, a linear precipitation zone has been analyzed, with some places experiencing torrential rain of 110mm per hour. Intense rain may continue intermittently throughout the morning.

Even if the rain weakens, high water levels will persist for several hours, so please do not go check the situation. Additionally, there is a risk of swelling and flooding due to insufficient drainage in tributary rivers, so vigilance is necessary even in places away from large rivers.

Follow evacuation instructions from local governments, and those living in flood-prone areas should evacuate to safety before reaching level 5. If the route to the evacuation center is not secure, ensure your safety in the upper floors of your home, away from slopes.

Even after the rain weakens, river water levels may rise, so please do not go to check the river.
