(BIVN) – The High Surf Warning that was in effect for East Hawaiʻi shores on Wednesday has been cancelled and a High Surf Advisory has taken its place.
The National Weather Service in Honolulu says a long-period, north northeast swell produced by a storm in the Northeast Pacific will generate surf heights of 10 to 15 feet along north facing shores of Molokai, Maui, and Big Island, and 8 to 12 feet along east facing shores of each isle.
The swell also brings the potential for surges in north facing harbors, including Hilo and Kahului Harbors, forecasters say. Mariners using these harbors should exercise caution when entering or leaving port and when mooring or launching vessels, the National Weather Service says.
On Wednesday, the high surf event closed the Hilo Bayfront Highway in both directions and shutdown the Laupahoehoe Boat Ramp.
According to Hawaiʻi County Civil Defense, surf is forecast to continue through this evening in the area from Upolu Point to Cape Kumukahi.
Due to the high surf, the county says the following are in effect:
- State Department of Transportation has Closed Bayfront Highway in both directions. Use Kamehameha Avenue as an alternate route.
- County Parks and Recreation has Closed Laupahoehoe Boat Ramp.
- Oceanfront residents and beachgoers along the affected shores are advised to be on the alert for high and dangerous surf.
- Boat owners and oceanfront residents should take action to secure their property.
- Closures of roads and beaches may occur without notice.
