Trade winds will relax a bit as a weak trough passes by the area. A mid-level disturbance will also bring a slightly less stable airmass over the state, which means we'll have an increase in windward and mauka showers for Sunday, especially at night and in the morning.
Longer term, trade winds will be light for much of the coming week as high pressure moves farther northeast from the islands. We're still tracking Tropical Storm Blas, which should weaken into a remnant low in the next 24 hours. Moisture from Blas may get caught up in the light trades and increase showers later in the week.
Surf on the south shore has fallen below advisory levels but head-high sets are still possible Sunday. There's also a long-period east swell from Blas that could bring east shore surf near advisory levels Sunday and Monday. For now, there are no marine warnings or advisories in effect.
