Flood Watch Issued as Heavy Rain Hits Hawaii
US · Published Oct 28, 2026
• A Flood Watch is currently in effect across Hawaii through Wednesday evening due to a complex weather pattern bringing deep tropical moisture to the islands.
• The approaching trough of low pressure, combined with moisture from Tropical Storm Olana, is expected to result in heavy rainfall and thunderstorms.

Impact & Risks

The heavy rainfall poses a significant risk of flooding, particularly in low-lying areas and regions near higher elevations. Thunderstorms accompanying the rain could lead to localized hazards such as flash flooding and reduced visibility. Residents in flood-prone areas should remain vigilant, as the accumulation of 2 to 8 inches of rain could overwhelm drainage systems. Travelers and outdoor enthusiasts should exercise caution due to slippery roads and potential disruptions.
