A slow-moving, torrential tropical storm pelting the Hawaiian islands with flash floods, high winds, and even blizzards at high altitudes has triggered a state of emergency.

The “Kona low,” as the storm system is called, is expected to last through Tuesday evening after hovering over the archipelago throughout the weekend and Monday. Hawaii Gov. David Ige signed the emergency order, which “allows the state to use funds to support state and county efforts in providing quick and efficient relief of suffering, damage, and losses,” Monday evening as flash flooding, road closures, power outages, and landslides remain dangers even in areas where the storm has passed.
