The beautiful islands of Hawaii are reeling from their worst flooding in more than two decades. From early to mid-March, powerful rainstorms swept across the islands, drenching communities with record rainfall and causing flash floods. The brunt of the storms was felt on Maui and Oahu, though impacts were reported across all five islands.

The heavy rain first began around March 13, when a strong Kona low moved over the islands. This seasonal storm system can bring heavy rain to Hawaii, especially when it lingers over the islands, as it did this year. By March 15, the rainfall intensified. Many areas on Oahu and Maui received 8 to 12 inches (20 to 30 cm) of rain over just two days. This is far above typical monthly totals. Soils became saturated, and streams and rivers surged to record levels.

On Oahu’s North Shore, thousands of residents were forced to evacuate as rising waters threatened homes. In some areas, the muddy floodwater even pushed houses off their foundations.

Meanwhile, on Maui, rising waters turned valleys and roads into fast‑moving, dangerous streams. Some low-lying areas were completely flooded, forcing residents to seek higher ground.

More than 230 people were rescued from floodwaters on Oahu and Maui. The storm also caused extensive damage to road and bridges on both islands. Across Hawaii, thousands of people were left without electricity at various points as flooding and high winds downed lines.

By March 21, 2026, the worst of the storm appeared to be over. As floodwaters recede, communities across Oahu and Maui are beginning the long process of recovery. Residents and volunteers are cleaning mud and debris from homes. Repair crews are working to restore roads and bridges. The American Red Cross and other nonprofits are providing food, shelter, and emotional support to those affected. Hawaii’s governor, Josh Green, estimates total damages could top $1 billion. This would make the storm one of the most destructive in the state’s history.
