Heavy showers and gusty winds are still possible as a Kona low continues to bring stormy weather to the islands.

The entire state is under a flood watch through Sunday night into Monday morning. Officials say additional rain on already saturated grounds could lead to sudden flooding. A winter storm warning is in place until 6 a.m. Monday for Hawaiʻi Island summits. (What does all the alert terminology mean?)

Crews with the Hawaiʻi Department of Transportation and contractors have been working to clear trees, rocks, and other debris from roadways on all islands. Some roadways are closed due to flooding or other weather-related conditions. Officials recommend staying put and to only travel if needed. All Maui Bus services are suspended until further notice due to hazardous road conditions from the storm.

The County of Maui Department of Water Supply set up drinking water tanks in several parts of Upper Kula late Saturday after a mainline break impacted area water service. Severe weather caused a water mainline break, resulting in low pressure and water outages. Due to inclement weather, it’s unclear when the repairs can be made.

The City and County of Honolulu’s Department of Environmental Services is asking residents to conserve water to help reduce strain on the wastewater system. Heavy rains are causing inflow and infiltration into the wastewater system, placing additional pressure on pump stations and treatment facilities. Conserving water helps lower the risk of sewer system overflows.

The County of Maui Department of Water Supply also advises all residents and visitors to conserve water due to potential power and electronic system disruptions. Non-essential water use should be limited until weather conditions improve.

On Kaua‘i, nearly 286,000 gallons of wastewater spilled approximately between Friday night and Saturday morning. The spill at the Waimea Wastewater Treatment Plant was due to high flows from the heavy rains and high infiltration and inflow from the storm. Officials say future spills may occur until the storm passes.

Officials advised postponing outdoor activities or travel until Monday or Tuesday when the storm begins to drift northward away from the islands.

The islands could experience winds of 25 to 40 mph with gusts up to 60 mph. Gusts on the summits of Maui and Hawaiʻi Island could reach up to 110 mph. A high wind warning for Maui and Hawaiʻi counties has been extended through 6 p.m. Sunday.

Hawaiian Electric said that, as of Saturday night, about 70,000 customers were without power on Oʻahu; 15,700 customers in parts of Maui County; and 28,300 customers on Hawaiʻi Island.

On Oʻahu, a majority of those without electricity are in the windward and east Honolulu areas due to storm-damaged high-voltage transmission lines that traverse the Koʻolau Mountain Range. A helicopter crew inspected the damaged lines. Repairing damage from the storm could take anywhere from hours to days or even longer as crews will need to navigate mountainous terrain, HECO said.

Various areas of Upcountry, South, Central and East Maui are impacted by power outages. Damage assessments and potential repairs are being stalled due flash flooding, downed trees, and road closures, the utility said.

On the Big Island, the majority of the outages are in the Puna area. North and South Kona, North Kohala, South Hilo and South Point are also experiencing outages.

Oʻahu, Hawaiʻi Island and Maui Nui residents can track Hawaiian Electric power outages here. Kauaʻi residents can track KIUC outages here.

The state Department of Land and Natural Resources has closed state parks and properties. All camping permits through next week have been canceled, and none will be issued for the rest of this week.

The National Park Service closed Haleakalā National Park on Maui from sunset Thursday through at least sunrise on Sunday. “We will open the park as soon as it is safe to do so,” park Superintendent Natalie Gates said in a statement.

Parts of Hawaiʻi Volcanoes National Park are closed or will close, including the Maunaloa summit. Road access is already impacted near Kīlauea’s Halemaʻumaʻu Crater due to cleanup after the recent eruption. Check the park website for the latest.

The City and County of Honolulu’s Department of Emergency Management has an online form Oʻahu residents can fill out to self-report damage to their homes. The purpose of the form is to collect information that will help local officials understand the damage and impacts the storm had on the community. The City will also use this information to determine whether it can request assistance from federal programs.

The Hawaiʻi Department of Commerce and Consumer Affairs (DCCA) Insurance Division is reminding residents to review their insurance policies and to file claims quickly. Starting claims promptly helps ensure coverage is applied correctly and delays are avoided. It has a post disaster claims guide and a video on how to file an insurance claim for additional help.

On Kauaʻi, county officials said they’ve received multiple reports of price gouging. Hawaiʻi law prohibits price increases during a state of emergency, and anyone caught doing so may be fined up to $10,000.

“These protections are meant to ensure that families can still access necessities like food, water, fuel, and other important supplies when they need them most,” Alden Alayvilla, the communications officer for Kauaʻi County, said in a statement.

Maui and Honolulu counties have not received reports of similar activity. Reports can be made to the state DCCA. Officials recommend taking photos of the price or keeping the receipt.
