The tsunami advisory has been dropped. The PTWC says tsunami wave heights across the state of Hawaii are now below advisory levels and are continuing to diminish. Based on all available data, the PTWC has cancelled the advisory.

Small sea level changes and strong or unusual currents may persist for several additional hours in some coastal areas and appropriate caution should be exercised by boaters and swimmers.

Looking Ahead

ARTICLE CONTINUES BELOW AD

Moderate to fresh trade winds are forecasted to bring passing showers across the islands during the next several days, with rainfall focusing over windward and mauka areas. Some of the larger areas of showers will reach leeward locations at times. Daytime heating will also continue to trigger afternoon and early evening showers over the leeward Big Island slopes and coast. Another round of unsettled weather is possible again this weekend into next week as an upper level disturbance approaches the islands from the northeast, and deep tropical moisture spreads over the state once again.
