Hawaii declares state of emergency due to severe winter storm

In early 2026, the Hawaiian Islands faced an intense period of severe weather that tested the state's resilience.

The most critical event occurred in March 2026, when a powerful Kona low system—a seasonal cyclone known for dragging subtropical moisture over the islands—unleashed devastating rainfall.

Governor Josh Green acted proactively, issuing an emergency proclamation on March 9th to mobilize the Hawaii National Guard and emergency agencies before the storm peaked.

The impact was historic, causing nearly $1 billion in damages and triggering fears that the aging Wahiawa Dam might collapse, which forced thousands to evacuate.

Infrastructure, including roads and local communities on Oahu and Maui, suffered greatly from flooding and landslides.

Experts warn that these heavy rain events are increasing in both frequency and intensity due to global warming.
