Honolulu residents can breathe a sigh of relief as moderate trade winds are predicted to maintain a steady course today, with a North Pacific disturbance granting leeward areas a few showers—some potentially heavy. The National Weather Service in Honolulu reports that the surface ridge to the north is currently flatter, ushering in stable conditions expected to last into the week.
According to the latest updates, scattered showers have been making their presence known in windward locations, occasionally gracing leeward communities. Forecasts suggest sea breezes could contribute to shower activity later in the day. "Moderate trades will prevail today with localized sea breezes developing in some of the more sheltered leeward areas this afternoon," the National Weather Service noted. On the horizon, slightly stronger trades are anticipated Tuesday through Friday, potentially loosening up over the weekend as the northern ridge loses some of its influence.
Furthermore, an upper-level atmospheric disturbance positioned northwest of the islands has been stirring up instability, which could yield robust showers and brief downpours. This atmospheric temperamental guest is forecasted to mellow out by Tuesday, giving way to a more serene weather pattern dominated by normal trade wind conditions—punctuated mainly by windward and mauka showers.
The aviation community will see moderate trades directing low clouds and scattered showers to windward and mauka regions. "MVFR conditions can be expected in any showers. Otherwise, VFR should prevail," as foreseen by the National Wether Services. The onset of stronger trades tomorrow may necessitate special attention for aviation regulations, such as AIRMETs, although none are currently in place.
As for the waters surrounding the islands, mariners should anticipate moderate to locally sprightly trade winds starting today. A Small Craft Advisory could go into effect for certain regions by Tuesday. Surf enthusiasts can look out for a moderate swell approaching the north-facing shores by mid-week, likely to lift waves to beyond head-high levels, but not quite reaching High Surf Advisory criteria. Meanwhile, the southern shores will remain calm, and the eastern shores should expect a slight rise in activity thanks to the strengthening trades.
