Forecast: Tracking a weak cold front and a massive swell

HONOLULU (HawaiiNewsNow) -

For most of the morning and early afternoon, the cold front has stalled over Oahu.  A blanket of low clouds is hovering over the Gathering Place.  Light rain is now turning into mist for many mauka spots on Oahu and some rain is forming over parts of Maui County.  We are expecting the front to hold together to bring rain to Molokai before it begins to dissipate over Maui County.  

Meanwhile, gentle northeast winds will bring some more showers over the Koolau mountains on Oahu through this evening.  Weather models are showing moderate rain amounts, and we are not expecting intense downpours since there is little upper level support associated with this system.  So far this morning, the North Shore of Oahu has received between 1/4" to 3/4" of rain during the passing of the front.

The front is also going to switch up our winds for a brief period. As of Friday afternoon, winds behind the front over Kauai have switched to the north/north-west and winds ahead of the front are still kicking up from the south.  The northeast winds are helping clear out the vog for Kauai and Oahu, but it is still lingering over Maui County along with sunshine for Hawaii Island.

As the front dissipates tonight, a nighttime land and daytime sea breezes wind pattern will return for all islands. Weather models are hinting that remnant moisture from the dissipated front may still provide some clouds and possibly even some light showers over the interiors of Oahu, Molokai and Kauai in conjunction with the sea breeze convergence Saturday afternoon. 

A High Surf Warning remains up until 6 pm Saturday.  Even though the swell will reach its peak this afternoon, it will take time for the waves to calm down. 

NWS Surf Outlook: 
Surf will remain elevated near advisory levels early next week, with a new northwest swell bringing advisory or possibly warning level surf once again on Wednesday.  On the North Shore, we are still expecting 30-40 ft today then dropping to 20-30 ft on Saturday along with large and dangerous sets on the West Shores.

High seas of 18 feet are expected this afternoon, so a Small Craft Advisory remains up for our coastal waters.

High surf warning until 6 pm HST Saturday for north and west facing shores of Niihau Kauai Oahu and Molokai, and for north facing shores of Maui

High surf advisory until 6 pm HST Saturday for west facing shores of the Big Island

Small craft advisory until 6 pm HST Saturday for all Hawaiian waters except Maalaea Bay
