At 11 a.m. Saturday, Jimena was about 720 miles east of Honolulu and 600 miles east of Hilo, moving northwest at 8 mph.

The heavy showers that drenched much of the state Friday moved offshore overnight, but the hot, humid weather will linger as Hurricane Jimena continues on a path to pass north of the main Hawaiian islands.

A flash flood watch for Hawaii island expired at midnight, although scattered showers could affect areas along the leeward coast, according to forecasters.

Weather officials issued a flood advisory for Kauai at 11:33 a.m. after radar showed nearly-stationary heavy rain near Kokee State Park.

Locations in the advisory include, but are not limited to, Polihale, Haena, Wainiha, Na Pali State Park, Kalalau Valley, Barking Sands, Kipu Falls, Waimea, Puhi, Princeville, Pakala Village, Mana, Kokee State Park, kekaha and Hanalei. The advisory runs through 5:15 p.m.

A flash flood watch remains in effect for Oahu, Kauai and Niihau until 6 p.m. Saturday.

A high surf warning for east shores of most islands has been extended until 6 p.m. Monday. A high surf warning for the south-facing shores of all islands was posted early Saturday morning and is in effect through 6 p.m.

Surf generated by Jimena will reach 10 to 18 feet on east shores, forecasters said. The dangerous swell could continue into next week.

A storm near New Zealand continues to whip up surf for the south shores, up to of 6 to 10 feet today.

Weather for much of the state will still be hotter and more humid than usual, forecasters say, with scattered showers and a chance of thunderstorms. Vog is also expected to move over Oahu Saturday through Labor Day.

Jimena is too far away to predict its exact impacts on Hawaii’s weather.

But Jimena, like Ignacio, is expected to cut off the tradewinds as it moves north of the state as a tropical storm.

That will mean the hot, humid weather and afternoon showers will likely continue through at least the early part of next week.

After that, Jimena could take a turn to the southwest, which could bring an increased chance of rain as the system moves closer to the islands.

But forecasters caution that a lot could happen in the next week and it is way too early to predict exact impacts.

At 11 a.m. Saturday, Jimena was about 720 miles east of Honolulu and 600 miles east of Hana moving northwest at 8 mph.

Jimena, now barely a hurricane, had sustained winds of 75 mph. The hurricane-force winds extend 15 miles and tropical storm force winds extend outward of 185 miles.

The storm is expected to continue toward the northwest with a slight increase in forward speed late Saturday into Sunday.

Out in the West Pacific, Typhoon Kilo is sending a small west swell to the state. West shores should see 3- to 5-foot wave faces through Saturday.
