Honolulu Fire Department and Ocean Safety personnel assisted a pair of one-man canoe paddlers Saturday as strong winds and high surf ushered in what is expected to be a windy and rainy three-day weekend.

The two paddlers ran into trouble in windy conditions off Black Point and called for help about 11:30 a.m., according to Department of Emergency Services spokeswoman Shayne Enright. One of the two men experienced fatigue and was brought to Kaimana Beach via personal watercraft by Ocean Safety personnel.

The blustery conditions prompted the National Weather Service to issue warnings and advisories.

A wind advisory is in effect for the main Hawaiian islands through 6 p.m. today as a high-pressure system to the north is expected to keep easterly winds of 25 to 30 mph — and gusts of more than 50 mph — moving across the island chain.

The weather service warned that high winds could bring down tree branches and make driving difficult.

Meanwhile, a high-surf advisory is in effect for east-facing shores of Kauai, Oahu, Molokai, Maui and Hawaii island through 6 p.m. Wednesday. A high-surf advisory is also in effect for the north- and west-facing shores of Niihau, Kauai, Oahu and Molokai and the north-facing shores of Maui through 6 p.m. Monday, as well as the west-facing shores of Hawaii island through 6 a.m. Monday.

Surf is expected to build to 16 to 22 feet along north- and west-facing shores of Nii­hau, Kauai, and Molokai and along north-facing shores of Oahu and Maui.

Oceangoers can expect strong breaking waves, shore break and strong longshore and rip currents.

The NWS also issued a small-craft advisory for Hawaiian coastal waters within 40 miles; a gale warning for Hawaiian offshore waters beyond 40 nautical miles and extending to 240 nautical miles; and a winter weather advisory for the Hawaii island summits.
