HNL Alert from the Oahu Department of Emergency Management

Issued: 07:52 AM 04-12-2026  

Heavy rain expected Sunday; open shelters and half marathon road closures in effect.

Officials continue to monitor weather conditions and respond to storm-related impacts across Oʻahu as a Flash Flood Watch remains in effect through 6 p.m. Monday, April 13.

Periods of heavy rain are expected Sunday, with moderate to heavy showers of 1” to 2” of rain per hour are forecast potentially through Monday morning. This creates the increased likelihood for additional flooding and landslides due to saturated ground and elevated stream levels. Residents are urged to remain vigilant and take necessary precautions.

Emergency Shelters:
Six City emergency shelters remain open across Oʻahu and will continue operations through at least Tuesday due to the ongoing weather threat and potential for additional rainfall. Shelters are open to both residents and visitors and are pet-friendly. Individuals are encouraged to bring essential items including food, water, medications, and pet supplies. Case workers remain onsite to assist occupants with housing plans as conditions evolve.
