Forecast: Hector to bring some changes to the islands

Hector weakens slightly as it approaches the islands.

Hurricane Hector remains a powerful Category 4 hurricane this morning, but the satellite presentation has degraded slightly since the previous advisory.

At 5 a.m., the storm was still a Category 4 with sustained winds of 130 mph and located 540 miles east-southeast of Hilo.

The forecast track will take the storm to the south of the islands, making it's closest pass sometime Wednesday afternoon.

The Big Island and parts of Maui could see some large surf along east shores.

Effective at noon today, a high surf warning will be posted for the Big Island's east shores. Waves there could be 12-15 mph.

Maui's east shores will be under a high surf advisory with waves expected to be 6 to 10 feet.

Otherwise, expect a dry trade wind weather pattern with breezy winds today with a strong high pressure system far to the north of the state.

A trade wind weather pattern remains in the forecast for much of the state with scattered shower activity favoring windward and mountain areas through the weekend.

Hurricane Hector will be passing into the Hawaii region later tonight through Thursday.

Wind speeds will trend higher across the state as Hector passes south of the island chain.

Enhanced shower activity remains in the forecast for the eastern slopes of the Big Island for the same time period.

Hector will then exit the region by Friday, with a return to typical summertime trade wind weather pattern for the Big Island.

Oahu waves today will be 3-5 feet east and south, 3 feet or less north, 2 feet or less west.

Tropical storm watch for the Big Island and coastal waters south and west.

Hurricane warning for all waters 40nm - 240nm offshore.

Gale watch for the Pailolo and Alenuihaha channels, along with Maalaea Bay.

Small craft advisory for the Kaiwi channel, Oahu Maui and Big Island windward coastal waters, along with coastal waters south and west of the Big Island.
