Two deaths have been confirmed in the aftermath of Hurricane Lowell in Hawaii.

Police in Kauai found the body of a 74-year-old man along the ocean shoreline near Nōmilu Fishpond. The man was first reported missing on Tuesday. Officials believe his death was related to Lowell's storm surge.

In Waimānalo, on the island of Oahu, a man died after a large tree fell on him on Monday, as Lowell swept just west of the islands. Gov. Josh Green said the man was living in a tent in a park.

Lowell didn’t make landfall, but it still brought intense winds and rain, hitting Kauai the hardest. Higher elevations in Hawaii got as much as 18 inches of rain.

Lowell’s impacts in Hawaii are the third time in less than a month that the state has experienced severe weather. Many communities were still recovering from storms that struck the islands just two weeks apart in August — Hurricane Lala and Tropical Storm Moke.

"We're going to get through this together," Mayor of Kauai Derek Kawakami said on Wednesday.

The damage that remains

Downed trees and power lines have caused widespread power outages. As of Thursday, about 16,000 customers are still without power, down from more than 60,000 at the height of the storm.

Many people are also without running water as local officials are working to restore service. The Kauai Department of Water has an islandwide conservation notice in effect. The outages have also affected pumps and wells, so pressure can drop even if for those whose homes weren’t damaged.

Brown water advisories were also issued for islands of Kauai and Oahu and parts of Maui. The Hawaii Department of Health recommends staying out of these affected waters for 48 to 72 hours after the rain has stopped and after the beach has received full sunshine.

Public schools in Kauai County will remain closed to students through Friday, according to the Hawaii State Department of Education.

Thick layers of sand covered the entire first floor of the Sheraton Kauai Resort after dangerous surf from Hurricane Lowell surged into the beachside hotel. The heavy rain, storm surge and sustained winds over 50 mph tore up roads and trees across the western Hawaiian island.

Support for residents and volunteers help with recovery

The Hawaii National Guard’s Task Force is on the ground in Kauai supporting as the island begins recovery efforts. A team of Red Cross volunteers were also deployed to help at five state-managed shelters and two places of refuge where more than 300 people have fled the storm.

Food distribution sites have been set up at locations across Kauai. They will be open over the next several days to help residents affected by the extended power outages.

Red Cross volunteers are working alongside local volunteers who have been helping people since Hurricane Lala hit the islands on Aug. 12.

Flooding and mudslides remain a risk as the massive cleanup begins.

For those aiding in storm cleanup efforts, officials have provided several points of guidance:

• Do not re-enter damaged buildings until electricity is shut off, gas lines are secured and the structure is deemed safe.
• When cleaning or entering affected areas, wear personal protective equipment: waterproof boots, heavy-duty gloves, an N95 mask, safety goggles or glasses, long sleeves and long pants.
• If you come into contact with flood water or flood debris, wash exposed skin with soap and clean water as soon as possible.
• Use alcohol-based wipes or sanitizer if clean water is unavailable.
• Do not eat, drink or smoke in contaminated areas.
