Dangerous surf and for some islands, a chance of heavy showers.

That cold front we were tracking yesterday just west of Kauai has dissipated as forecast. Just a few showers are expected for windward and mauka neighborhoods across the state this morning.

Light and variable winds will give way to sea breezes with the convective heating this afternoon, and interior areas could see clouds and showers form. For the Island of Hawaii and to a lesser extent Maui, the afternoon and evening could be very different. Moisture moving up from the south could be enhanced by some instability aloft. That may result in heavy showers or thundershowers for the east end of our island chain.

The wet weather could continue into Friday for Maui and the Big Island.

Stable and mostly dry weather should be in place for the weekend across the state.

Advisory-sized surf is building along north and west shores today and will peak this afternoon with heights approaching warning levels.

An even bigger northwest swell is expected late Friday, peaking on Saturday. Officials are advising those who work or live along those shorelines to get ready.

Waves today will be 20-24 feet north, 14-18 feet west, 2-4 feet east, 1-3 feet south.

High Surf Advisory north and west shores of Niihau, Kauai, Oahu, and Molokai. North shores only for Maui and the Island of Hawaii.

Small Craft Advisory for most Hawaii waters due to large open ocean swell.

Box jellyfish are expected along south shores. Check with lifeguards before you or the kids get in the water.
