Heavy rains turned a key corner of Windward Oahu into a no-go zone on Monday, with Waikane Valley Road and a stretch of Kamehameha Highway shut down after fast-rising water made the roadway impassable. Honolulu police closed the intersection at Waikane and urged drivers to steer clear while water and debris remained on the pavement. Officials had not given any estimate on when the road might reopen.
According to KITV, the Honolulu Police Department shut down Kamehameha Highway from Waikane Valley Road to the Waikane Store and asked the public to avoid the area and use caution. In its March 23 report, the station noted that crews were monitoring conditions but offered no timetable for when traffic might resume.
The traffic mess is the latest fallout from a burst of intense Kona-storm rainfall that hammered parts of Oahu earlier in the week, prompting rescues and evacuation orders in some communities, as reported by the Associated Press. That system led to multiple road closures across Windward Oahu and stretched emergency crews as they responded to stranded residents.
Why this stretch floods
The Waikane area lies below steep watersheds that channel runoff into the Waiahole and Waikane streams, which can swell quickly during heavy downpours. Streamgage data for Waiahole Stream above Kamehameha Highway show clear flood-stage thresholds and sharp spikes in flow during storms; recent readings are available from the USGS…
