A flood advisory for the island of Hawaii has expired, but a flash flood watch remains in effect through Sunday afternoon.

1:15 pm

The National Weather Service has issued a flood advisory for the island of Hawaii until 4:15 pm today.

At 1:11 pm, radar indicated heavy and near-stationary rainfall over the lower slopes of Kona, impacting the area from Holoualoa to Keahole Point. Rain was falling at a rate of up to 1 inch per hour, and additional heavy rain was expected to continue on the slopes this afternoon.

Locations in the ad include, but are not limited to, Kailua-Kona, Captain Cook, Kealakekua, Kainaliu, Honaunau, Honalo, Kahaluu-Keauhou, Holualoa, and Kalaoa.

The public should stay away from streams, drainage ditches, and low-lying areas prone to flooding, while still being aware that rain and runoff will cause dangerous driving conditions.

No one should cross swift or rising waters by vehicle or on foot.

THE PRESENT DAY

Heavy surf, strong winds, a flash flood watch and snow for the Big Isle peaks are part of the forecast for Hawaii’s weather today.

High surf warning continues for the east coasts of all major islands as high winds, with localized gusts of up to 45 mph, continue today across parts of Maui County and the island of Hawaii.

The National Weather Service expects a 9 to 13 foot swell along the east coast of all the islands from Kauai to the island of Hawaii today until 6 a.m. Monday.

The impacts are moderate but strong, the crashing waves and currents will make swimming difficult and dangerous, and beach lovers should heed all advice from ocean safety officials.

Elsewhere, the swell is steady at 4 to 6 feet for the northern shores, 3 to 5 feet for the southern shores, and 2 to 4 feet for the western shores, today and Saturday.

The wind advisory for parts of Maui County and the island of Hawaii was extended until 6 p.m. today, and may be extended further tonight, due to easterly winds of 20 to 30 mph, with localized gusts of up to 45 mph.

Such strong winds are capable of knocking down trees and temporary structures and causing local power outages.

Today’s forecast includes partially to mostly cloudy skies, with isolated rains and highs of 79 to 84 degrees Fahrenheit. The skies tonight remain mostly cloudy, with lows of 67 to 72 degrees.

Forecasters said the strong and gusty operations are expected to continue into early next week. Trade winds may ease slightly tonight, but a new high is expected to move over the weekend, boosting trading once again.

The NWS has also issued a flash flood watch for parts of the island of Maui and Hawaii, in effect from 6 p.m. today through Sunday afternoon.

Meteorologists say that a “persistent trough in the air” will bring the possibility of an extended period of rain to the windward areas of Maui and the island of Hawaii. Repeated heavy rain bands saturating the ground will create an increasing threat of flash flooding over the weekend.

Periods of snow and freezing rain are also expected for the summits of Big Isle due to the freezing temperatures that depression brings.

A winter weather advisory remains in effect for the summits of Mauna Kea and Mauna Loa until noon Monday.

Authorities warn that traveling to the summits could be very difficult due to the icy roads.

A gale warning remains in effect for the Alenuihaha channel until 6 pm Friday.

A small craft advisory remains in effect for all waters from northwest Kauai to the southeast of the island of Hawaii until 6 p.m. Sunday.
