A powerful kona storm system is bringing a combination of hazardous weather impacts across the Hawaiian Islands through the weekend, including significant flash flooding, damaging winds, snow and ice over the highest Big Island summits, and strong to severe thunderstorms. The National Weather Service has issued a Flood Watch for Maui County and a High Wind Watch for Maui County as the storm system lifts northward.

Why it matters

Kona storms can bring widespread disruption and damage to the Hawaiian Islands, with the potential for flash flooding, power outages, and dangerous travel conditions. The closure of popular parks and recreation areas highlights the severity of the weather impacts and the need for residents and visitors to heed weather warnings and take appropriate safety precautions.

The details

Damaging wind gusts are forecast along the north and east sides of the island mountains from Friday into Saturday. Unsettled wet weather conditions with southwesterly winds will continue into early next week before high pressure builds back in, allowing trade winds to return.
