Additionally, a high surf advisory remains in effect for Oahu, Kauai and Molokai’s west-facing beaches and north-facing Maui beaches.
Both the warning and advisory are in effect until 6 a.m. Tuesday. The warning applies to Niihau, Oahu North Shore, Kauai North, Koolau Windward, Molokai Windward and Molokai North Shores.
Forecasters are warning of dangerously large breaking waves about 25 feet high on the affected islands. On Hawaii Island, expect large breaking waves of 12 to 16 feet across the northern beaches.

A flood warning is in effect for Oahu as a weak cold front moves over the Hawaiian Islands from the northwest today.
At 6:46 a.m., radar showed heavy rain falling on East Oahu at a rate of 0.5 to 1 inch per hour, according to the National Weather Service. A flood warning was later posted until 9:15am today.
Some of the locations that will experience flooding include Honolulu, Waihole, Waikana, Kahalu’u, Ahuimanu, Kaua`a, Ia, Pearl City, Halawa, Kaneohe, Moanalua, Punaluu, Salt Lake, Mililani, Kalihi, Kaneohe Naval Base, Wahiawa, Maunawili, Haula and Kailua. .
“Rainfall and runoff will also cause hazardous driving conditions due to puddles, reduced visibility and poor braking action,” NWS officials said in a bulletin this morning.
The advisory may need to be extended if flooding continues.
The cold front moving slowly down the island chain today is expected to stop over Maui County later today, forecasters said. Clouds and rain will develop from Kauai to Maui through Tuesday.
The newly returning trade winds will be a local breeze today after the cold front from Kauai to Molokai, and will retreat to typical trade wind weather Tuesday into Friday.
A high surf advisory remains in effect for the north and west beaches of Niihau and the north shores of Kauai, Oahu, and Molokai while a high surf advisory remains in effect for the west beaches of Kauai, Oahu, Molokai and the north shore of Maui until Tuesday at 6 a.m.
A large swell from the north-northwest grew overnight and will continue to expand eastwards, bringing “dangerously high” waves to exposed northern beaches and high surf on western beaches today, weather officials said. The swelling is expected to gradually weaken and move north on Tuesday.
“Dangerous breaking waves” near 25 feet are expected in warning areas, while surf heights of up to 15 feet are expected in advisory areas, according to the National Weather Service.
