Kauai is set to experience a significant increase in moisture and rainfall starting late Wednesday, September 16, 2026, due to remnants of Tropical Storm Norbert.
Moderate trade winds will strengthen to breezy levels, with inversion heights ranging from 7,500 to 8,500 feet.

Impact & Risks

The increased moisture and heavy rainfall could lead to localized flooding, especially in windward and mountainous areas. The National Weather Service has not issued any watches or warnings yet, but a flood watch may be announced as conditions evolve. Breezy winds of up to 20 mph (32 km/h) could also create hazardous conditions for small watercraft and outdoor activities. Residents and visitors should remain vigilant, particularly during the late-night hours when heavy rainfall is most likely.
