A high-surf warning remains in effect until at least 6 p.m. today for the north and west shores of Oahu, Kauai, Niihau and Molokai and the north shores of Maui.

A less urgent high-surf advisory is in effect for the west shores of Hawaii island, the National Weather Service said.

A large northwest swell was expected to peak today after building overnight, the weather service said.

Surf today will be 25 to 35 feet along the north and west shores of Kauai and Niihau and the north shores of Oahu, Molokai and Maui; the west shores of Oahu and Molokai can expect surf of 15 to 25 feet. This will produce strong breaking waves and rip currents, and could generate surf in harbor channels, the agency warned.

Surf will be 8 feet along the west shores of the Big Island.

The waves will likely diminish tonight and Tuesday, forecasters said.

A small-craft advisory remains in effect until 6 p.m. Tuesday for Hawaii waters except for the lee of Maui County, with east winds of 17 to 29 mph and seas of 10 to 15 feet.

Senators to hear plan for ditches from plantation era

Improving plantation-era ditches that connect dams around Anahola, Kauai, will be the subject of an informational briefing Jan. 14 before the state Senate Ways and Means Committee.

The $2.5 million in improvements are part of Gov. David Ige’s supplemental budget request, the Garden Island reports.

If approved by the Legislature, the capital improvement project will enable agricultural production on Hawaiian homelands, a Department of Hawaiian Home Lands spokeswoman said. The improved irrigation system would make as much as 106.2 million gallons available to DHHL’s agricultural homesteads.

It will also address long-standing infrastructure concerns. The reservoirs and irrigation systems at Anahola “represent a liability to the DHHL, with the maybe potential for another (Ka Loko) type disaster,” the department wrote in its June 2010 regional plan for Anahola, referring to the 2006 dam break near Kilauea that killed seven people.

Currently, 46 agriculture lessees oversee property on the department’s Anahola lands. But there are roughly 2,100 applicants waiting to secure agricultural leases of their own on Kauai, including some who have been waiting for decades.
