As severe weather approaches Hawaii, residents are advised to review their insurance policies and consider adding flood insurance. DTRIC Insurance Vice President Mike Mishima emphasizes the importance of documenting belongings through photos and videos, including specific details about appliances. In the event of storm damage, it is crucial to capture evidence before any cleanup and to report claims to insurance companies promptly. Mishima also recommends securing important documents in water-tight storage and suggests digital backups as an alternative.
