Analysis
Hakui and Himi
The cities of Hakui and Himi experienced unprecedented rainfall, setting new records for precipitation within a 24-hour period. Hakui, in Ishikawa Prefecture, and Himi, in Toyama Prefecture, each received approximately 350 millimeters of rain by Thursday afternoon, significantly exceeding their August averages. This deluge overwhelmed local river systems, leading to the Inoyama River in Hakui overflowing its banks and causing widespread flooding. The intensity of the rain, with some areas like Shika reporting 100 millimeters per hour, overwhelmed drainage and levee systems, resulting in submerged homes and vehicles.
Ishikawa Prefecture
Ishikawa Prefecture bore the brunt of the severe weather, with 10 rivers flooding and several levees failing. The impact was visible in footage showing houses and cars submerged in water, and roads rendered impassable. Approximately 270 households became isolated due to landslides blocking access. Governor Yukiyoshi Yamano acknowledged the difficulty in preparing for such extreme natural forces, emphasizing the prefecture's efforts to assist those affected, including isolated residents, those with inundated homes, and evacuees in shelters. The focus is now on restoring infrastructure and helping residents return to normalcy.
Japan Meteorological Agency Warnings
The Japan Meteorological Agency (JMA) initially issued the highest-level emergency rain warning (Level 5) for parts of Ishikawa and Toyama prefectures, signifying a life-threatening situation and urging immediate safety measures. This warning was later downgraded to Level 3, which advises evacuation for vulnerable groups like the elderly. Additionally, widespread Level 4 alerts for landslides remained in effect, also calling for evacuations. The JMA forecasts continued heavy rain, with 200 mm expected in Ishikawa and Toyama by Friday noon, and an additional 80 mm over the subsequent 24 hours, indicating a persistent threat from the unstable weather system.
