Residents of Fukui Prefecture are cleaning flood damage under a heatstroke alert following record-breaking rainfall this week [1, 2].
The situation creates a dangerous secondary crisis for survivors. Those clearing debris from flooded homes must now contend with extreme temperatures that increase the risk of heat-related illness during physical labor.
Heavy rains hit the region on Friday, leading to the issuance of a Level 5 emergency warning, the highest alert level [1]. In Katsuyama, recorded rainfall exceeded 350 millimeters within a 24-hour period [1]. The flooding caused significant property damage, including submerged homes and collapsed furniture [1, 2].
By Saturday morning, authorities had lifted all emergency safety measures and evacuation orders [1]. However, the relief was short-lived as a heatstroke alert was issued for the prefecture. Local forecasts indicated maximum temperatures would exceed 35 degrees Celsius [1], while broader national warnings suggested some areas could approach 40 degrees Celsius [5].
In the Maruoka district of Sakai City, residents began clearing ruined belongings from the streets early Saturday morning. The volume of debris remains high as families struggle to salvage what remains of their possessions.
"On the streets of Maruoka in Sakai City, many items have been put out due to the effects of yesterday's heavy rain," a reporter said. "Cleanup work is being carried out at a rapid pace from early this morning" [2].
The physical toll of the cleanup is compounded by the psychological stress of the disaster. One local resident expressed frustration over the scale of the task.
"I wonder when it will ever be cleaned up," the resident said [2].
“Cleanup work is being carried out at a rapid pace from early this morning”
This sequence of events illustrates the increasing prevalence of 'compounding disasters,' where a primary weather event is immediately followed by another extreme climatic condition. For Fukui, the transition from a Level 5 rain emergency to a high-temperature alert limits the window for safe recovery, forcing residents to choose between delaying essential cleanup or risking heatstroke.
