Destructive surf, locally damaging winds, and periods of squally weather for our Sunday, as a powerful winter storm system moves southeastward. 

The area of low pressure is just over 200 miles to the north of Kauai this morning, tracking 35 mph, and will pass just north of the islands tonight.

Winds will increase throughout the day, building to 25-40 mph, and gusts to 60 mph.

The storm system is also sending scattered showers, and potentially thunderstorms, that will continue throughout the weekend.

Some of the rain may be briefly heavy, accompanied by gusty winds.  Expect a cloudy, wet and windy day for both windward and leeward sides. 

Afternoon highs will only reach the mid 70s.

Unsettled weather may continue into the middle of the week as the storm lingers to the northeast of the state, with a more typical trade wind weather pattern later in the week. 

A Winter Weather Advisory has been issued by the National Weather Service for Haleakala Summit, where snowfall, wind, and unusually cold temperatures are expected. 

Out on the water, a High Surf Warning is posted for north and west facing shores of Kauai, Niihau, Oahu, and Molokai, north facing shores of Maui, and west facing shores of the Big Island. 

A High Surf Advisory is in place for north facing shores of the Big Island and west facing shores of Lanai, Maui, and Kahoolawe. 

Surf: N 40-60', W 30-40', E 4-7', S 3-5'.

A Gale Warning is in effect for waters around Kauai County, with a Gale Watch and Small Craft Advisory elsewhere. 

The National Weather Service has issued a Marine Weather Statement, extreme surges are expected for north and west facing harbors. Mariners should exercise extreme caution when using harbors this weekend.
