Hurricane Hector was the strongest ever overnight, with sustained winds of 140 mph at its center. It is forecast to slowly weaken as it approaches the islands and track just to the south of us.

With its current forecast, we will see some big surf along east and south shores, stronger trade winds, and perhaps some increase in moisture for the Big Island.

Just a slight deviation in the track could bring big changes to the storm's impact on Hawaii. Stay alert and stay in touch with us, your Severe Weather Station.

Meanwhile, it's the calm before the storm. Very stable and dry trade wind weather is expected today. Trades will blow 15-20 mph and bring just a few passing showers.

High in Honolulu will be 90 degrees. A high pressure system northwest of the Hawaiian Islands is what's keeping breezy trade winds in the forecast through Tuesday.

Drier and more stable air moving across the region will keep shower coverage limited to mainly windward and mountain areas through Tuesday afternoon.

Hurricane Hector will cross into the local region from Tuesday night into Thursday and it remains too early to determine specific impacts on island weather at this time. Hector will likely clear the region by Friday, with typical summertime trade wind weather heading into next weekend.

Surf is slightly elevated along east shores and the south side is getting a little bump.

Waves today will be 2-5 feet east, 2-4 feet south, 3 feet or less west, 2 feet or less north.

Hurricane Warning for all waters 40 - 240 nautical miles offshore.

Small Craft Advisory for the Pailolo and Alenuihaha channels, Maalaea Bay, along with coastal waters south and west of the Big Island.

Box Jellyfish are likely along south shores today and tomorrow.
