Overnight camping in state parks on Maui, Oahu and the Big Island has been canceled for the Labor Day weekend, as Lester approaches the state.
But city parks on Oahu are still allowing camping -- for now.
The state Department of Land and Natural Resources said that all camping and lodging areas on the Big Island, Maui and Oahu will be closed for overnight use beginning Friday and won't reopen until Monday, at a minimum.
The parks will remain open for daytime use.
Meanwhile, the gates at Kaena State Park, which normally open at 2 p.m. on Fridays for weekend access, will remain locked through the weekend.
The closures mean many Oahu residents will have to change their plans for the holiday weekend.
Kahana State Park and Malaekahana State Recreation Area are among the state parks where overnight camping won't be allowed starting Friday.
In a news conference Friday, Honolulu Mayor Kirk Caldwell said city parks (including Hanauma Bay) will remain open for now. But he urged residents to stay tuned, and warned that plans could change if the hurricane tracks closer to the island.
