Hawaii Torrential Rains Threaten Century-Old Dam Collapse; Over 5,000 Evacuated | WPN World People News

Hawaii has recently been hit by intense torrential rains, triggering severe flooding. Authorities have also warned that a roughly 120-year-old dam is at risk of collapsing, prompting emergency evacuation orders for more than 5,000 residents as the situation grows increasingly critical.

The disaster has mainly affected northern parts of Oahu, where days of heavy rainfall have caused rivers to swell and muddy floodwaters to overflow. Streets have been submerged, vehicles swept away, and some homes have even been dislodged from their foundations. Local authorities activated emergency alert systems, urging residents living downstream of the Wahiawa dam to evacuate immediately to prevent further escalation.

According to reports from the Associated Press and other media outlets, the dam—built in the early 20th century—has long been considered structurally vulnerable. Rapidly rising water levels during the storm have pushed it close to its capacity, with officials warning it could “fail at any moment,” triggering heightened alarm. Authorities noted that some areas recorded over 200 millimeters of rainfall in a short period, saturating the ground and overwhelming drainage systems, allowing floodwaters to spread quickly. The event is being described as one of the most severe floods in the region in over two decades.

Rescue efforts are ongoing, with more than 200 people already evacuated from affected areas, including airlifts conducted by helicopter. Some residents have been hospitalized due to hypothermia, though no fatalities have been reported so far. However, rescue operations have been complicated by disrupted transportation and interference from civilians flying drones to capture footage of the disaster.

In addition, the flooding has caused extensive property damage, with numerous homes destroyed or washed away entirely. Critical infrastructure—including roads, schools, and medical facilities—has also been impacted. Hawaii Governor Josh Green stated that economic losses from the disaster could exceed $1 billion.

Meteorological authorities indicated that the extreme rainfall is linked to a Kona low weather system, with further rainfall expected in the coming days. Officials are urging residents to remain vigilant and comply with evacuation orders. Experts also warn that as climate change intensifies, extreme rainfall and flooding events may become more frequent, posing growing risks to aging dams and infrastructure.
