UPDATE: Honolulu is preparing for a wave of heavy rainfall over the next several days, with the National Weather Service (NWS) urging residents, mariners, and aviators to take immediate precautions. The weather forecast indicates a typical rainy spell as a dissipating front west of Kauai transitions into a trough, creating conditions ripe for showers predominantly affecting windward and mauka areas starting Saturday and continuing into early next week.
Residents should expect a gradual strengthening of southeasterly winds today, pushing showers towards the east and southeast slopes of the islands. While trade winds will ease slightly, the shift to an easterly direction may enhance rainfall during certain periods, though no significant sources of moisture have been detected in the latest predictions.
Aviation warnings are in effect, with potential moderate turbulence and low-level wind shear impacting PHOG this afternoon, despite the generally favorable VFR conditions expected. The NWS emphasizes the importance of heeding these warnings as pilots navigate through changing weather patterns.
Mariners are also on alert with a Small Craft Advisory in place until early Saturday for Maui County and Big Island waters. Forecasts predict combined seas exceeding 10 feet due to a moderate to large northwest swell. With surf conditions along northern and western shores intensifying, a High Surf Advisory may be issued as the incoming swell peaks.
The oceanic activity coincides with monthly spring tides, raising concerns for minor coastal flooding during early morning peak tides. Additionally, as trade winds strengthen later on, east shore surf is expected to become choppier, further complicating maritime activities.
Despite these weather advisories, the NWS currently predicts that critical fire weather conditions are unlikely this week in Honolulu. Relative humidity levels are near seasonal norms, and light winds are expected to increase only to moderate strength, keeping fire risks below critical thresholds.
Officials are closely monitoring the evolving weather situation, as forecasts remain subject to change. Residents are advised to stay updated on the latest developments and take necessary precautions as conditions shift.
This evolving situation highlights the importance of being prepared for sudden weather changes, and residents are encouraged to share this information widely to ensure everyone stays safe during the upcoming rainy spell.
