High pressure north of the Hawaiian Islands is keeping moderate to breezy trade winds in place, with windward and mauka showers and drier conditions leeward. Forecast updates show a higher chance of rain over the Big Island’s windward slopes later today. Trade winds are expected to ease and shift more easterly early next week as the surface ridge weakens. "The mid-level ridge should remain strong enough to maintain stable conditions," with only a small chance of tropical moisture reaching the Big Island, though it will more likely pass to the south, according to the National Weather Service.
High pressure north and northeast of the islands is keeping trade winds moderate to breezy, with showers mainly over windward and mountain areas at night and early morning. The National Weather Service says aviation conditions will remain mostly VFR, with brief MVFR possible in showers. A Small Craft Advisory is in effect through Sunday for windy waters near Maui County and the Big Island. Surf will be choppy along east shores, south swells will ease over the weekend, north shores will stay calm, and a Coastal Flood Statement is in effect for minor flooding during afternoon high tides.
The National Weather Service reports that moderate to brisk trade winds will continue through Sunday, with a high-altitude ridge keeping conditions stable and dry. Afternoon humidity levels are expected to reach the 40s percent range. "We do not anticipate fire weather headlines through the weekend, but fire weather concerns will be elevated," the National Weather Service stated. Residents, along with maritime and aviation interests, are advised to monitor forecasts for the latest updates.
