While current forecasts suggest Calvin will weaken below hurricane status before reaching the state, County officials maintain that it is essential for Big Island residents to remain vigilant and prepared for potential hazards. The County emphasizes the importance of recognizing the potential impacts, which include heavy rains and flooding, high surf and high winds that can affect the islands.

As part of the County’s commitment to public safety, all residents are urged to be proactive and take appropriate preventive measures to safeguard themselves and their property before conditions become hazardous. Residents can stay informed about the latest updates by following guidance from public messaging from outlets including the National Weather Service and Hawaiʻi County Civil Defense.

The Hawai‘i Tourism Authority is also closely monitoring Hurricane Calvin as it approaches the islands.

The Hawai‘i Department of Transportation also is taking steps to be prepared for possible impacts from Calvin or its remnants.

Contractors are being notified about potential storms and possible flooding, and DOT crews and the contractors they work with routinely check drains and bridges, rockslide areas and low-lying spots along roadways.

At airports, DOT staff will work with tenants to ensure aircraft are secure, as well as other heavy equipment, and at harbor districts are in communication with the U.S. Coast Guard so appropriate action can be taken with harbor users and tenants should storm conditions require any port closures.

DOT crews also will take proactive steps such as topping off gas tanks of work vehicles in the field, as well as generators at airports, harbors and other facilities.


The department advises everyone to follow directions from local emergency management. Travelers should check with their airlines and cruise lines about possible delays.

Anyone who comes across a flooded road is advised to inform police and not to attempt to cross it. If you see downed utility lines, they should be treated as energized and authorities should be notified.

Any emergency updates from the DOT will be posted to its Facebook and Twitter feeds.
