Honolulu will continue to experience breezy trade winds, with unstable conditions persisting into the early morning due to a weak upper low moving westward across Hawaii. However, more stable air is expected from the east later today, which should reduce local shower activity through Wednesday, according to the National Weather Service forecast.
Island residents can expect a brief break from rain, but rainfall is forecast to increase from late Wednesday into Friday due to deep tropical moisture leftover from former Hurricane Kristy. While heavy showers are likely, a flood watch has not been issued yet. The weekend may bring drier conditions and milder trade winds.
Aviation warnings have been updated, indicating moderate to heavy showers, especially on windward slopes, with the chance of isolated thunderstorms over Kauai this morning. Breezy easterly trade winds are expected to continue. The National Weather Service has updated AIRMET Sierra for mountain obscuration in the northern and eastern sections of Kauai, and AIRMET Tango remains in effect for temporary moderate low-level turbulence. Maritime conditions will also be affected by strong easterly trades, which are expected to persist through Friday before possibly easing over the weekend.
Mariners and beachgoers should be aware of challenging conditions, with a Small Craft Advisory in effect for parts of Oahu and the Big Island. Surf conditions will vary by shore: east-facing shores are likely to be rough due to strong trade winds, while north and south shores may see fluctuating surf sizes from different swell energies. This weekend could bring increased surf activity from swells originating near Kamchatka in the far northwest Pacific.
