Authorities in Hawaii have begun closing several parks and hiking trails as a powerful storm system threatens to bring intense rainfall, strong winds, and potential flooding across the islands this week.

Officials with the Hawaii Department of Land and Natural Resources (DLNR) announced multiple closures as part of safety precautions while the storm approaches. Weather forecasters warn that the developing system could produce severe weather conditions through the weekend.

The closures come as the National Weather Service issued warnings about a powerful kona storm expected to move across several Hawaiian islands.

State of Emergency Declared as Storm Approaches

Governor Josh Green declared a state of emergency ahead of the incoming storm to ensure emergency resources can be deployed quickly.

In a video posted online, Green urged residents to take the weather threat seriously and prepare for hazardous conditions.

“Our priority is keeping the people of Hawaii safe,” the governor said, cautioning drivers and residents to be extremely careful in the coming days.

Meteorologists say the storm could bring heavy rainfall, thunderstorms, and powerful winds, with some areas potentially receiving over 20 inches of rain. Flooding could impact both smaller islands and densely populated urban areas.

State Parks and Trails Shut Down Across Islands

In response to the forecast, authorities have shut down several parks and trails across the state to protect residents and visitors.

Kauaʻi Closures

On the island of Kauaʻi, multiple popular outdoor destinations were closed beginning Monday afternoon.

• Polihale State Park closed to both day-use visitors and overnight campers starting at 3 p.m.

• Kalalau Trail has been closed until further notice.

• Kōkeʻe State Park allowed campers to remain until Tuesday morning at 11 a.m., after which all camping activities were suspended.

  
  
  

Officials say the closures will remain in place until the storm passes and conditions improve.

Oʻahu Access Restrictions

On the island of Oʻahu, authorities also implemented access restrictions.

Vehicle access to the Mokulēʻia section of Kāʻena Point State Park was scheduled to close at 1 a.m. Tuesday.

Officials with the DLNR’s Division of Conservation and Resources Enforcement and State Parks staff have been working to notify campers and hikers and assist with evacuations from affected areas.

Residents Urged to Avoid Coastal and Forest Areas

Authorities warned that dangerous conditions may develop quickly as the storm intensifies.

Residents and tourists have been urged to stay away from coastal areas and forests, where hazards could include:

• Flash flooding

• Rising streams

• Falling trees

• Storm surge

• High surf

Those already in remote areas that could become inaccessible due to road closures or flooding have been advised to shelter in place if evacuation becomes unsafe.

Flood Watch in Effect Through Saturday

A flood watch remains in effect until Saturday, according to weather officials.

Emergency management authorities are advising residents to prepare for possible disruptions, including:

• Power outages

• Road closures

• Large waves and coastal surge

• Strong winds and thunderstorms

Residents are also being encouraged to identify evacuation routes, prepare emergency supplies, and make plans for pets and vulnerable family members.

The state has also suspended all camping permits in state parks until further notice as the storm threat continues.

Kona Storm Expected to Move Across Islands

The storm is expected to first impact Kauaʻi, Niʻihau, and Oʻahu, before spreading to other islands later in the week.

Meteorologists warn the weather system could intensify as it moves across the state, bringing worsening conditions in the coming days.

Officials say they will continue monitoring the situation closely and provide updates as needed.
