FIRST ALERT: Swell brings High Surf Advisory level waves; North and West shores, Niihau to Maui
Next 5 days: Lots of sunshine with a few windward showers at times
HONOLULU (HawaiiNewsNow) - Mostly drier trend through the weekend with light to moderate trade winds. Some brief windward showers, but probably not enough to make it over to the leeward side.
We know that vog from Kilauea Volcano/Hawaii Island can make some people uncomfortable; Kilauea being just above 4,000 ft above sea level. The eruption of Mauna Loa is about the 13,000 ft level, which means most of the particulate will not affect lower elevation populated areas of any of the islands. National Weather Service, HVO and USGS continue to monitor this dynamic situation.
A large, long period west northwest swell will build in today, peak tonight and Friday morning and then gradually fall Friday night into the weekend. This swell is expected to be large enough to increase north and west-facing shore surf, due to the more westerly swell direction, to High Surf Advisory (HSA) levels on the main islands (except Big Island) today. This swell may push north and west surf heights up to near High Surf Warning (HSW) thresholds at its peak tonight through Friday morning. This west northwest swell may sneak into Big Island’s western waters Friday and increase the odds for placing their west-facing shores within a HSA. A northeast swell moving into our nearshore windward waters Saturday may also lift north and east-facing shore surf across many islands to near HSA levels over the weekend.
