The National Weather Service issued a high surf advisory for the south shores of all islands through noon Saturday.
A large swell from east of New Zealand is expected to bring high surf to south shores in Hawaii. Surf of 6 to 8 feet is expected to build today, peak tonight and subside on Saturday.
Expect strong, breaking waves, shore break and strong currents, making swimming dangerous.
The NWS also issued a special weather statement for Hawaii island about an ash plume generated by a 5.5-magnitude earthquake at 2:45 a.m. today at the Halemaumau Crater at Kilauea. Moisture from a large cloud plume rising from Kapoho was expected to produce ice accumulations on the roads leading up to the summit on Maunakea until 8 a.m. today.
Wind directions, meanwhile, are expected to shift to a more easterly to southeasterly direction through Saturday morning, pushing any ash and particulates toward the west and northwest of volcano emission sources.
Trace amounts of volcanic ash and Pele’s hair will likely occur over northern Kau, Puna, portions of the South Hilo area and Saddle region. This includes the communities of Pahoa, Kapoho, Hawaiian Beaches, Hawaiian Paradise Park, Glenwood, Mountain View, Nanawale and portions of Hilo.
Vog emissions are also expected to push further northwest, approaching the smaller isles in the chain later this afternoon through Saturday evening. The Hawaii Interagency Vog Information Dashboard is at vog.ivhhn.org.
