Big Island Flooding Update: Highway 11 Reopens After Heavy Rainfall (2026)

The recent deluge on the Big Island of Hawaii has left residents and authorities alike grappling with the aftermath of heavy rainfall and flooding. While the wet season may have officially ended, the island's windward regions were drenched, with some areas receiving over 10 inches of rain in just 24 hours. This deluge caused significant disruptions, including the closure of Highway 11, a vital transportation route, between mile markers 57 and 62. The closure, which lasted from 11:30 a.m. to 9 p.m. on Tuesday, was a stark reminder of the challenges posed by the unpredictable nature of Hawaii's weather. What makes this particularly fascinating is the contrast between the official end of the wet season and the intense rainfall that followed. In my opinion, this event highlights the importance of staying vigilant, even when the rainy season has seemingly come to a close. The heavy rainfall not only caused flooding but also led to the closure of roads, affecting both residents and visitors. The Hawaii Police Department's decision to reopen a portion of Highway 11 near Kawā and Honuʻapo in Kaʻū was a welcome relief, but it also underscores the need for better preparedness and alternative routes in the event of such weather events. One thing that immediately stands out is the significant impact of the rainfall on various locations across the Big Island. From Saddle Quarry to Honoli'i Stream, the rain gauges recorded impressive totals, with some areas receiving over 13 inches of rain in just 24 hours. This raises a deeper question: How can we better prepare for and mitigate the effects of such intense rainfall events? The flooding not only caused inconvenience but also raised concerns about the safety of residents and the potential for damage to infrastructure. What many people don't realize is the vulnerability of certain areas to flooding, even in the face of seemingly mild weather conditions. If you take a step back and think about it, the impact of this rainfall event extends beyond the immediate closure of roads. It highlights the need for better drainage systems, more robust infrastructure, and a deeper understanding of the island's unique weather patterns. The event also serves as a reminder of the importance of community resilience and preparedness. As residents and authorities, we must work together to ensure that we are ready for whatever nature throws our way. This includes investing in better infrastructure, improving communication networks, and fostering a culture of preparedness and awareness. In my view, the recent flooding on the Big Island is a call to action for all of us. It is a reminder that we must be proactive in addressing the challenges posed by our unique and often unpredictable weather patterns. By taking steps to improve our preparedness and resilience, we can better protect our communities and ensure a safer, more sustainable future for all.
