Heavy rain near western Akita city
A cold front is passing from Hokkaido to northern Tohoku. Rain clouds have developed locally in Akita Prefecture, and radar analysis shows that regarding 100 mm of heavy rain fell in the hour up to 11:20 p.m. in the western part of Akita City, making it a record-breaking day. “Hourly heavy rain information” has been announced. AMeDAS observed extremely heavy rain of 50.5 mm in Nibetsu in the hour up to 11:30 p.m.
Heavy rain and flood warnings have been issued for Akita City, Oga City, Katagami City, and Ikawa Town, and landslide warning information has been issued for Akita City, Akita City, and Katagami City. (As of 23:50)
Please be wary of landslides, flooding of low-lying areas, flooding of roads, and rising river waters due to heavy rain. If you live in an area at risk of landslides or flooding, moving to a pre-determined evacuation site may actually be dangerous. In such a case, move to a safer place, such as a safer place nearby or a room on the second floor or higher.
What is record-breaking short-term heavy rain information?
Weather observatories around the country make announcements when they observe and analyze short-term heavy rains that only occur once every few years. Standards vary by region. This announcement is made to notify the region of “rarely observed rainfall that might lead to the occurrence of a disaster.”
When to evacuate? What is the timing?
Disasters such as landslides and river flooding can occur suddenly and cause damage, so delaying evacuation can be life-threatening.
Therefore, the timing of evacuation is important. In case of Alert Level 3, elderly people and people with disabilities should evacuate to a safe place. At Alert Level 4, everyone in the target area should evacuate immediately. When alert level 5 is reached, a disaster has already occurred, and life-saving actions are required. It may be difficult to safely evacuate once the alert level reaches 5, so early evacuation is necessary.
When the weather gets rough, the risk of evacuation increases, such as poor road conditions and objects being blown away by strong winds. Even if an evacuation order has not been issued, if you feel even the slightest danger, evacuate yourself. If you feel unsafe, now is the time to evacuate. When evacuating, please be aware of the idea of “voluntarily evacuating to a safe place as soon as possible,” and when evacuating, call out to your neighbors and evacuate in groups.
