(BIVN) – A High Surf Advisory is in effect for the north-facing shores of Hawaiʻi Island, the National Weather Service in Honolulu says, while a Wind Advisory is in effect for the summits of Mauna Kea and Mauna Loa.
Surf is expected to peak today, building to 12 to 18 feet along exposed north facing shores of the Big Island. Forecasters note the swell coming in is lower than expected. Waves will gradually lower tonight.
Another large northwest swell is expected on Tuesday. The swell will peak “well above warning levels Tuesday night,” forecasters say, and “exposed coastal waters will once again rise to over 10 feet as these swells come rolling through.”
At the summits, northeast winds of 30 to 45 mph with localized gusts to 55 mph have triggered a Wind Advisory, in effect until noon today.
The winds atop Mauna Kea and Mauna Loa “can make driving difficult, especially for high profile vehicles,” forecasters say.
According to Hawaiʻi Volcanoes National Park, the summit of Mauna Loa is closed due to the Wind Advisory.
