Honolulu is preparing for several days of gusty conditions as a high-pressure system strengthens north of the islands, bringing stronger trade winds, increased cloud cover, and showers over windward and mauka areas. "Trades are anticipated to be strongest on Wednesday," with wind speeds possibly exceeding advisory thresholds in some locations, according to the National Weather Service.
Later in the week, the high-pressure system is expected to move northeastward, gradually weakening the winds, though showers may increase over Maui and the Big Island due to moisture from a developing low and frontal boundary. Aviators and mariners are advised to remain cautious, as breezy to windy trades may cause turbulence and high seas, with an ongoing AIRMET Tango and potential Gale Warnings in effect, as reported by the National Weather Service.
Coastal areas may experience significant wave runup, beach erosion, and localized flooding on north- and east-facing shores. A High Surf Advisory is in effect and may be extended. Surfers may see increased surf from "a pulse of long period south swell energy." Fire warnings remain due to dry and windy conditions, but "inversion heights will remain around 6,000 to 7,000 feet today."
