The National Weather Service has extended a flood watch for the entire state of Hawaii, including Kauai County, through 6 p.m. on Monday, April 13. Forecasters warn that flash flooding from heavy rainfall remains possible, with the potential for significant flooding of roads, streams, and low-lying areas, as well as landslides in steep terrain. The public is advised to monitor forecasts and be prepared to take action if flash flood warnings are issued.

Why it matters

Hawaii is prone to severe weather events, and flash flooding can pose a serious threat to public safety and infrastructure. The extended flood watch underscores the need for residents and visitors to remain vigilant and prepared, as heavy rains and saturated soils increase the risk of dangerous flooding and landslides.

The details

The National Weather Service says a disturbance approaching from the northwest is expected to bring renewed deep tropical moisture across all Hawaiian Islands starting late tonight. Given the already saturated soils and elevated stream levels following recent heavy rainfall, forecasters warn that flooding could redevelop quickly. Multiple road closures have already been reported along the Kokee Contour Road on Kauai due to erosion caused by the severe weather.
