Rough ocean conditions today are affecting roads and beach parks on Hawaii island and Maui so far as a high-surf warning remains in effect for most islands.

The state Department of Transportation said Bayfront Highway in Hilo is closed in both directions due to high surf.

On Maui, Baldwin Beach Park is closed today due to flooded conditions at its access road and pavilion. Officials said rough ocean conditions also prompted the closure at Ho‘okipa Beach Park.

The high-surf warning is in effect until 6 a.m. Tuesday, according to the National Weather Service.

Surf is expected to reach 18 to 28 feet tonight along the north shores of Oahu, Maui, Big Island and Molokai and the north and west shores of Kauai County.

Kim Tamaoka, spokeswoman of Kauai County, said ocean safety officials have warned numerous beachgoers to stay out of the water at affected shores.

Surf on the west shores of Oahu and Molokai are expected to reach 15 to 25 feet this morning and drop to 12 to 18 feet tonight.

On Hawaii island, surf on the north shore is forecast to reach 15 to 25 feet this morning and decrease to 8 to 12 feet tonight.
