First Alert Forecast: Could more rain be arriving to the islands this weekend?

HONOLULU (HawaiiNewsNow) – It is windy for now, but the winds will gradually slow down later this week and then enhanced showers especially for Friday into Saturday. Just wanted to give you a first alert heads up.

Breezy trade winds will continue across the islands through Thursday, keeping the typical spring weather pattern in place with passing showers focused over windward and mauka communities, especially overnight and during the early morning hours.

Leeward areas should still see plenty of sunshine overall, though brief showers may occasionally drift through on the stronger trades. The breezy conditions will also make it feel a bit cooler and rougher along east-facing shores and channels.

Looking ahead to Friday and the weekend, the forecast becomes a little more unsettled.

An upper-level disturbance moving near the islands will increase atmospheric instability while deeper tropical moisture spreads into the state.

That combination could lead to muggier conditions, more widespread trade wind showers, and pockets of heavier rainfall — mainly along windward slopes and mountain areas. While it is still too early to pinpoint exact locations, localized downpours and ponding on roads are possible, particularly during nighttime and morning periods.

For beachgoers and boaters, rough and choppy east shore conditions will continue due to the strong trades, while a new northwest swell arriving Thursday will provide a modest boost to north and west shore surf. South shores will remain relatively small but steady.

Mariners should be aware that Small Craft Advisories remain posted for many Maui County and Big Island waters through Thursday because of the gusty winds and rough seas.

By early next week, the extra humidity may linger before trade winds strengthen again around midweek, helping return the islands to a more typical breezy trade wind pattern.
