Kauai Northwest Waters-Kauai Windward Waters-Oahu Windward Waters-
Maui County Windward Waters-Big Island Windward Waters-
A very large north swell will continue to impact the coastal waters tonight and Friday. The swell...and strong northeast winds will combine to produce large breaking waves in north facing Harbor entrances and may cause Harbor surges. Haleiwa Boat Harbor...Hilo Harbor and Kahului Harbor are likely to be affected. Mariners using these harbors should exercise caution when entering or leaving port and when mooring or launching vessels. The swell is expected to slowly subside through Friday.
