A low northwest of the state will swing east before lifting north today and be absorbed is a stronger, nearly stationary, low far northwest of the state. A front just west of Kauai associated with the low will move eastward pushing a broad band of showers eastward across the state through the day. Strong southerly winds ahead of the front will shift over Oahu this morning with light westerly winds filling in behind the front. Drier and lighter winds are expected to fill in across the state Saturday as the front pushes east of the state and weakens. Chance of showers will increase again across the state Sunday into early next week. Land/seabreezes will dominate much of the weather pattern next week as the low remains north of the state.

Two main areas of showers were moving through the state this morning. The first, mainly impacting Oahu, will bring widespread MVFR with isolated IFR. This area will work east towards Maui County through the afternoon, bringing worsening conditions. The other is over Big Island, and MVFR is likely there through at least this morning. The first area described may get to Big Island late this afternoon.

As the low pressure system to the northwest further deepens, we will likely see a few strong to severe thunderstorms capable of producing waterspouts and damaging winds over the coastal waters. Rough boating conditions are expected with elevated seas and strong to near gale force southerly winds. As such a Small Craft Advisory is in effect for all waters through at least 6PM.
Strong southerly winds are expected to slowly decrease west to east today. Surf along the southern shores is slowly declining. The High Surf Advisory has been cancelled as surf has fallen below criteria.
Along north facing shores, the current northwest (320 degree) swell is slowly decreasing and should dissipate to background levels on today. However a smaller short-period northwest swell generated by the aforementioned low will fill in tonight through early next week.
Surf along east facing shores could see an increase later this week due to the strengthening southeasterly winds especially for southeast exposures.
