The National Weather Service in Honolulu forecasts steady trade winds and brief showers for the Hawaiian Islands into next week. A high-pressure system to the north is maintaining these conditions, with rain expected mainly over windward and mountain areas, typically occurring at night through morning. A weak upper-level low will bring isolated thunderstorms to the western slopes of the Big Island on Saturday afternoon, according to the National Weather Service.
The National Weather Service forecasts the subtropical ridge to influence the region’s weather for the next seven days, maintaining moderate to strong easterly winds. An upper-level trough near the Central Pacific is causing instability and some rain this morning, affecting roads for commuters. There is a chance of unsettled weather ahead. Flight conditions will mostly be VFR, but brief periods of MVFR are possible in passing showers, especially near windward airports.
"A Small Craft Advisory (SCA) is now in effect for most marine zones east of Oahu through 6 am Saturday, and for some of the windier zones around Maui and the Big Island through 6 pm Saturday." Strong trade winds caused by high pressure northeast of the state will continue until the weekend when a distant trough may reduce winds. North and west-facing shores will see little surf activity, south-facing shores will experience a moderate increase from southern swells, and east-facing shores will remain steady with no significant changes, as reported by the National Weather Service.
