Additionally, due to potential inclement weather, the Kilauea Certified HI5 Bottle Redemption Center, located at 5-2723 Kūhiʻō Highway, is closed. Updates will be given if conditions improve.

Boaters should prepare for gusty winds, steep and fast-building seas, and blinding downpours. Stay low or go below, and make sure all on board are wearing life jackets.

Boaters should seek safe harbor immediately until this storm passes. Wind gusts 34 knots or greater, small hail, high waves, dangerous lightning, and heavy rain are possible with this storm.
