Raging waters have forced over 5,500 residents across Oahu and Maui to evacuate their homes.

Up to 12 inches of rain fell rapidly on land already completely soaked by recent winter storms.

The sudden deluge pushed a 120-year-old dam on Oahu to the brink of failure, triggering urgent emergency alerts.

On Maui, communities still recovering from the devastating 2023 Lahaina wildfires now face overflowing retention basins.

State officials estimate the sweeping damage to schools, roads, hospitals, and homes could top $1 billion.

These specialized winter storms pull deep, moisture-laden tropical air directly across the Hawaiian islands.

Global heating increases the atmosphere's capacity to hold water, supercharging the frequency and intensity of these downpours.

Because mountain soils are already saturated, even minimal new rainfall instantly turns into hazardous runoff.

Hawaii's crisis highlights the urgent need to upgrade community resilience against back-to-back extreme weather events.
