Honolulu Flood Watch: What to Do Now
Stay out of floodwater and move to higher ground immediately if flash flooding occurs.
If you are in Honolulu, the National Weather Service Honolulu office lists a Flood Watch for Oʻahu, including Honolulu Metro, through 12:00 a.m. EDT on October 9, 2026. Excessive rainfall may cause flash flooding. If you encounter floodwater, do not enter, cross, or drive through it; turn around and move to higher ground immediately. The watch may be updated, canceled, or replaced before that time, so check the latest official alert before relying on the stated end time.
