LIHU`E, KAUA`I (Ben Caxton) — Forecasters say giant waves are on the way for Kaua`i this weekend. A strong storm system with Gale force winds passing by 500 miles to the northwest will send a large north-northwest swell to the islands. Surf is expected to rapidly build early Sunday morning, peak Sunday evening into Sunday night at giant levels and steadily decrease Monday into Tuesday. Due to the combination of the giant surf, strong northerly winds, and near peak monthly high tides, overwash of low-lying coastal areas and roadways is likely Sunday through Monday, with the most vulnerable time frame around the high tide cycle Sunday night. Also, significant beach erosion can be expected and strong harbor surges may cause damage to boats and infrastructure along north and west facing coastlines and harbors.
