The closures at Hawai'i Volcanoes National Park aim to ensure the safety of visitors and staff. Areas near the coastline and those prone to flooding or landslides are particularly vulnerable. The park has also warned of potential unannounced closures if conditions worsen. Visitors and residents are urged to stay informed and avoid outdoor activities during the storm.
