The National Weather Service in Honolulu on Thursday issued a number of weather advisories for the Big Island that remain in effect throughout the coming days.
A high surf advisory is in effect until 6 p.m. Saturday for east-facing shores of Hawaii Island. According to the NWS, surf will increase to 7-10 feet. Strong breaking waves, shore break and strong longshore and rip currents can make swimming difficult and dangerous.
“Beachgoers, swimmers and surfers should heed all advice given by ocean safety officials and exercise caution,” the NWS said. “Know your limits; when in doubt, do not go out.”
A winter weather advisory is in effect until 6 p.m. today for the summits of Mauna Loa and Maunakea.
According to forecasters, a wintry mix of rain, snow and freezing rain is expected for the summits. Up to 2 inches of snow could fall. Forecasters cautioned of hazardous road conditions because of the wintry mix.
“Be prepared for slippery roads and limited visibilities and use caution while driving,” forecasters wrote.
A wind advisory also is in effect until 6 p.m. today for portions of the Big Island, including Hilo, Volcano, South Point, Pahala, Waikoloa, Honokaa and Waimea.
According to the NWS, east-northeast winds from 20-35 mph are expected, with gusts up to 50 mph. Winds that strong can down tents or other temporary structures, and can also down trees and cause power outages.
A small craft advisory remains in effect until 6 p.m. Saturday for leeward, windward and southeast waters around the Big Island. East winds could reach 25 knots and conditions could be hazardous to small crafts, according to the NWS.
A gale warning also is in effect through 6 p.m. today for the Alenuihaha Channel between the Big Island and Maui. East winds could reach 35 knots. Strong winds will cause hazardous sea conditions that could capsize or damage vessels.
“Operating a vessel in gale conditions requires experience and properly equipped vessels,” said the NWS. “It is highly recommended that mariners without the proper experience seek safe harbor prior to the onset of gale conditions.”
Nuisance coastal flooding also is expected during high tide throughout Friday morning for areas on the Big Island, including Kona and southern and northern parts of the island, the NWS said.
