Hawaii’s rare winter storm dumps snow on Mauna Kea and triggers flood alerts

Hawaii is facing an unusual early winter storm, bringing heavy rain, strong winds, and even snow to the islands. The severe weather has forced the closure of the access road to Mauna Kea’s summit, where freezing temperatures and thick snow have created hazardous conditions.

A powerful low-pressure system from the northwest is sweeping across Hawaii, causing heavy rain, squalls, and unseasonably cool temperatures. The National Weather Service (NWS) has issued multiple warnings for flooding, high winds, and dangerous coastal conditions expected to last through the first half of the week.

At 4,200 metres, Mauna Kea—the state’s highest mountain—has seen temperatures drop below freezing. A snow layer up to 25 centimetres thick now covers its peak, a common occurrence at high altitudes in Hawaii but still disruptive. Authorities have closed the summit road due to ice and snow, cutting off access for visitors and workers. Lower regions are also at risk, with meteorologists warning of heavy squalls, flash flooding, and waves exceeding three metres. Coastal areas may experience significant wave surges, increasing the threat of erosion and damage to shoreline properties.

The storm has brought rare winter conditions to Hawaii, with snow on Mauna Kea and severe weather warnings in place. Residents and travellers are advised to stay updated on alerts as the low-pressure system continues to impact the islands this week.
