As the remnants of what was once tropical cyclone Hector disperse, Honolulu locals can anticipate more sun and stable conditions heading into the Labor Day weekend. The National Weather Service in Honolulu reports this morning's weak low level trough, which increased clouds and shower activity over Oahu and Kauai, is now on the wane. "Clouds and showers will trend lower by this afternoon, as the trough continues to weaken and drift westward," according to the NWS Honolulu weather forecast.
The fading trough is promptly followed by a rise in high pressure that promises a significant reduction in humidity and the ushering in of moderate to locally breezy trade winds. These winds are expected to last into the next weekend, providing residents with a drier and more comfortable outdoor experience. A transition to these less humid conditions is said to start today, as large scale subsidence lowers the temperature inversion across the Hawaii region.
In terms of air travel, the transition back to normal trade wind patterns is forecasted for this afternoon and should bring about general VFR conditions, although MVFR conditions might occur in showers. "Low cigs and SHRA will mainly impact windward and mauka areas this morning," the NWS further explains. For mariners, a strengthening high pressure north of the waters will elevate trade winds through to midweek, calling for a Small Craft Advisory through tomorrow night in certain areas.
Surfers can expect the east facing shores to decline in wave activity today, settling into small choppy waters tomorrow, as even the south facing shores cling to small background swells, avoiding a complete flat spell. For those looking to enjoy the waters or hoping for a long weekend sail, be advised that the Small Craft Advisory is in effect until 6 AM HST Tuesday for several channels and coastal areas around Maui County and the Big Island. This advisory encompasses Maalaea Bay, Pailolo Channel, and the Big Island Leeward and Southeast Waters, ensuring safety for vessels susceptible to stronger winds and choppy conditions.
