First Alert Forecast: No tsunami threat after 4.6 magnitude earthquake off Kona coast plus big waves from south swells and passing showers

HONOLULU (HawaiiNewsNow) – Right before 6 pm, the USGS put a 5.2 magnitude earthquake statement and then changed it to 4.6 off the Kona coast. No tsunami threat.

As far as weather, a plume of tropical moisture moving in from the southeast is bringing a wet day across the islands, with showers becoming widespread this morning and continuing to spread westward through the day.

The heaviest rainfall has been focused over the eastern end of the state, particularly on the Big Island, where a Flood Advisory remains in effect for some windward and southeast communities throughout the day and even last night.

While trade winds are helping keep the wettest conditions focused on windward and mauka areas, some showers are making their way into leeward locations as well. With so much moisture in the atmosphere, brief periods of heavy rain are possible statewide today, which could lead to ponding on roads, reduced visibility, and localized flooding in low-lying areas.

Conditions are expected to gradually improve from east to west beginning Wednesday as the moisture and weak trough move away. A more typical Hawaii weather pattern returns for the second half of the week, with strengthening trade winds bringing the usual passing showers to windward and mauka communities while leeward areas see more sunshine.

For those heading out on the water, fresh to strong trade winds continue to create rough conditions around Maui County and the Big Island, with Small Craft Advisories in effect for many waters. South shore surf is on the rise thanks to a long-period south-southwest swell and could approach warning levels by late Wednesday.

North shores will also see increasing surf through the week from a pair of out-of-season north swells, while east shore surf gradually builds as the trades strengthen.
