HONOLULU (HawaiiNewsNow) – Isolated heavy showers and thunderstorms will be in the weather mix Sunday night and Monday as a moist and unstable southeast wind flow remains over the islands. The greatest threat will be for windward areas of all the islands, with Kauai and Oahu having the highest chance for downpours.

At this point, the chance for flooding is not high enough for a Flood Watch, but you get a First Alert if one is issued.

The unstable conditions are expected to persist Monday. An active shower pattern will slowly diminish Tuesday into Wednesday. with locally breezy trade winds filling in through at least Friday. Winds may decline again in the upcoming weekend.

In surf, a small to moderate north-northwest swell is expected to peak early Monday morning with some slightly overhead sets. Choppy surf will continue for east shores as the trade winds build over the coming week. A small boost in south shore surf may be possible as soon as Monday night as a series of small long-period swells moves through the islands.
