HONOLULU (HawaiiNewsNow) - A High Surf Advisory is now in effect for the north and west facing shores of Niihau, Kauai, Oahu and Molokai and the north shores of Maui until 6 a.m. Thursday, replacing the high surf warning that had been in effect.
Forecasters said surf is diminishing to 15 to 20 feet tonight and 8 to 12 feet Thursday. Along west facing Shores, surf is diminishing to 10 to 15 feet tonight and 4 to 8 feet Thursday.
On Kauai, officials closed all North Shore beaches, from the Hanalei Pavilion to Kee Beach to swimming due to high surf conditions. Ocean Safety officials reported wave heights of up to 20 feet in these areas.
Another large northwest swell arriving Friday is expected to produce surf reaching the high surf warning criteria along north and west facing shores of most of the smaller Hawaiian Islands Friday night and Saturday.
Meanwhile, the National Weather Service (NWS) says that the recent dry and relatively cool weather pattern will soon give way to southerly winds, volcanic haze and increasing showers.
The NWS says the weather pattern will spread across most of the state starting Thursday. "This unsettled weather will occur ahead of a front that is expected to move down the island chain from Friday through early Saturday."
Models indicate that there may be sufficient low-level moisture and atmospheric instability to produce some brief periods of localized heavy showers this weekend.
