Honolulu is seeing a weather reroute as the surface level trough and accompanying upper-level low pack up their bags and head west of Kauai, taking the brunt of the moisture with them. According to the latest bulletin from the National Weather Service, island residents can look forward to decreased shower activity from Tuesday into Thursday as a result of this departure. It's not all sunshine and rainbows quite yet, though; come the weekend, another upper-level trough is expected to make an appearance, likely ushering in a fresh wave of trade wind showers and a weaker cold front to cool things down a tad for the western islands.
Forecasters are keeping their eyes peeled today for a sliver of tropical moisture that could add some zest to the Big Island's weather, notably the windward and southeast slopes, where showers may get a little more persistent. "Later today, a pocket of tropical moisture will extend north, clipping the Big Island," as stated by the National Weather Service, signaling a wetter spell for that area while the rest of the islands should see more typical trade wind-induced showers.
For those taking to the skies, the aviation forecast spells out mostly VFR conditions, though some sections of the Big Island might see cloud and shower activity stirring up MVFR conditions. But for now, flyers can breathe easy with no AIRMETs currently in effect. Seafarers have a bit of a rougher ride with seas over 10 feet expected to continue through the day for the northwestern coastal waters, though this should simmer down by tonight below Small Craft Advisory levels.
Surf's not quite up to standards of yesteryear for anyone hoping to catch a sizeable break. The high surf advisory has already been canceled this morning with the north-northwest swell dropping just below those trigger levels. However, there's a glimmer of hope as the forecast teases "pulses of medium and long period swell energy continuing from the northwest to north direction," which might just merit dusting off your longboards for next week's waves, as noted by the National Weather Service.
The fire weather outlook is looking non-threatening with no critical conditions expected in the coming days, thanks to increased relative humidity and moderate trades. Those on the Big Island and Maui can expect inversion heights hovering between 7,500 to 8,500 feet today, keeping the fire risk at babble. On the marine front, the advisory flags are waving for some coastal areas, with a Small Craft Advisory in effect 'til 6 PM HST this evening for several zones around Kauai and Oahu.
