A flash flood watch expired for Oahu and Kauai as what's left of former Tropical Storm Iselle gradually moved west. Storm surf also prompted a high surf advisory for east shores of several islands.
The flash flood watch expired at noon as morning rains eased on Oahu and Kauai.
Clouds and showers should clear in the afternoon on Oahu and by evening on Kauai.
Winds will come from the north as Julio passes. The light north winds Sunday and Sunday night may allow some afternoon showers to form in leeward areas. Similar light wind conditions are expected for Monday.
Trade winds will return in the wake of Julio's passage Tuesday, reaching Kauai on Wednesday.
A flood advisory for Kauai expired at 10 a.m. as rains eased, and a flash flood warning for Kauai lapsed at 4 a.m. Heavy rain overnight blanketed the island, causing a rapid rise in the Hanalei River.
Also Saturday morning, the weather service canceled a flash flood watch for Maui County and the Big Island that had been in effect since Thursday afternoon.
A high surf warning is in effect until 6 a.m. Monday for east shores of Kauai, Oahu, Molokai, Maui and the Big Island.
Waves with faces of 8 to 12 feet was coming ashore Saturday morning and the surf should rise to up to 15 feet as another swell generated by Hurricane Julio arrives.
The Health Department is also warns beachgoers to stay out of brown water contaminated with runoff from overflowing cesspools, sewer manholes, pesticides, animal fecal matter, dead animals, pathogens, chemicals, and other flood debris.
The runoff is also known to attract sharks because of possible dead animals being washed into the ocean.
"This is definitely not the time to be recreating in Hawaiian waters," the Health Department said in a news release.
