Swell Summary
Surf along east facing shores will quickly rise late Tuesday, then peak Tuesday night into Wednesday as Tropical Storm Calvin approaches and moves through near or over the Big Island. A downward trend is anticipated through the second half of the week as Calvin begins to move away and dissipate south of the smaller islands. Heights may reach the advisory level Tuesday night through Wednesday for east facing shores, with warning level surf not out of question for the east facing shores of the Big Island. Small surf is expected elsewhere.
