A strong high will build north of the state while remnants of Fausto continues to weaken and shifts far northwest. Breezy easterly trades will strengthen to locally windy levels Friday afternoon and evening then hold into Saturday. A drier and more stable airmass will also settle in over the state that could produce very windy downsloping winds that may warrant a Wind Advisory. Trades will ease back to the usual breezy levels Sunday into early next week as the high weakens. Typical summertime showers are expected for windward and mountain areas.
Moderate to breezy trade wind weather will prevail through the period. Occasional MVFR ceilings and lowered visibilities over windward and mauka areas may occur within brief, heavier showers.
No AIRMETs are currently in effect. Friday's lower level trades may strengthen enough to warrant an AIRMET TANGO across and immediately S through W of high terrain.
Trades strengthen into Friday in support of the current Small Craft Advisory (SCA). Further expansion of the SCA may be warranted as strong trades become established this weekend.
The current medium period S swell will fade through the weekend. A mix of small south swells over the next few days will maintain surf along S facing shores slightly below the seasonal average.
An E swell will arrive tonight and persist through the weekend. This swell is a combination of the short period trade wind swell and the medium to long period east swell generated by Hurricane Genevieve in the East Pacific. N shores will see flat to tiny surf through early next week.
Small Craft Advisory from 4 AM Friday to 6 AM HST Saturday for Big Island Windward Waters-Kaiwi Channel-Maui County Leeward Waters-Maui County Windward Waters.
Small Craft Advisory until 6 AM HST Saturday for Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters- Maalaea Bay-Pailolo Channel.
