A resilient Oʻahu starts with communities that are informed, prepared, and able to support one another.
In 2025, the City launched HNL Alert, a new mass notification system that allows residents and visitors to sign up for updates about severe weather, emergencies, and other important community news via text message, push notification, or email. The new system allows for real-time updates that help the public make informed decisions for their safety. The City urges everyone to sign up, stay informed, and be prepared—there are two ways to sign up for HNL Alerts:
Text “HNLALERT” to 888777 to quickly subscribe to the most important alerts by text.
Create an account at hnlalert.gov to customize preferred alert topics and notification methods.
Effective emergency response also requires sound pre-disaster planning. In 2025, the City updated and adopted its Local Hazard Mitigation Plan. The plan identifies strategies and actions for reducing local risks from hazards like flooding, tsunami, wildfire, and sea level rise. FEMA’s approval of this updated plan maintains the City’s eligibility for many federal grant programs that support hazard mitigation efforts.
The City’s hazard mitigation efforts also help residents better understand and prepare for risks before disasters occur. Following FEMA’s release of updated Flood Insurance Rate Maps for Oʻahu, the City conducted extensive outreach throughout 2025 to help residents understand evolving flood risks across the island and upcoming regulatory changes before the maps take effect in June 2026.
Properties newly classified in high-risk areas must comply with flood hazard area regulations and may be required to obtain flood insurance. Through the City’s participation in FEMA’s National Flood Insurance Program (NFIP) Community Rating System, eligible NFIP-backed policyholders benefit from discounted flood insurance premiums.
