Central Pacific — Hawaii
Hawaii faces hurricane threats from both the Central and Eastern Pacific. With limited evacuation options and remote geography, preparing before the season is not optional.
⚠ Hawaii's Unique Risk
Hawaii's island geography means there is no evacuating the state once a storm is close. Storm surge, flooding, and high surf can isolate communities for days. Prepare fully before the season — not after a storm is named. The Central Pacific hurricane season runs June 1 – November 30.
Storm History
While direct hurricane landfalls on Hawaii are rare, significant storms have struck or come dangerously close:
Category 4 direct hit on Kauai on September 11, 1992. The most powerful hurricane in Hawaii's recorded history. Sustained winds of 145 mph. Caused $3 billion in damage, killed 6, and left tens of thousands homeless. The island took years to fully recover.
Approached Oahu as a Category 4 before weakening. Even as a tropical storm, Lane dropped record rainfall — up to 52 inches on the Big Island. Caused catastrophic flooding in Hilo and East Hawaii. A near-miss for Honolulu.
Made landfall on the Big Island's Puna district as a tropical storm, the first storm to directly strike a populated Hawaiian island since Iniki. Downed trees, destroyed homes, cut power to thousands.
A Category 1 that struck Kauai — the last hurricane to make landfall in Hawaii before Iniki. Reminder that the gap between major storms is not a guarantee of safety.
The lesson from each of these storms: when a storm threatens Hawaii, you cannot leave the state. Preparation must happen before the season begins.
Island-by-Island
Northernmost main island, no geographic protection from westward-tracking storms. Iniki (1992) proved a Category 4 landfall is possible. Limited evacuation routes within the island itself.
Largest island and geographically exposed to Eastern Pacific storms. The Big Island's landmass can disrupt storm tracks, but flooding from rainfall (Lane, Iselle) is a severe independent risk regardless of wind strength.
Includes Maui, Molokai, Lanai, and Kahoolawe. Partially sheltered by the Big Island from the southeast, but exposed to storms approaching from the south and west. Flash flooding risk is significant across all islands.
Home to Honolulu and 1 million residents. Partially protected by Maui County, but a direct storm from the south or southwest is possible. Hurricane Lane (2018) demonstrated that even a weakening storm can cause catastrophic rain-flooding on Oahu.
Smaller islands with limited infrastructure and medical resources. Hurricane prep is critical because emergency response takes longer to reach these communities. Stock 7+ days of supplies.
Primarily uninhabited atolls and marine refuges. Midway Atoll is under U.S. Fish and Wildlife Service management. Tropical cyclones in this region are tracked by CPHC but do not threaten populated communities.

Hawaii-Specific Guidance
Shipping disruptions after a major hurricane can last days to weeks. FEMA's standard 3-day recommendation is insufficient for an island state. Plan for at least 7–14 days of water, food, and medication.
Once a hurricane watch is issued, flights will fill and airports may close. You cannot evacuate the state. Know your county's designated shelters and your evacuation zone before the season starts.
Hawaii's steep terrain turns moderate rainfall into flash floods. Streams can rise 10+ feet within minutes. Even if a hurricane weakens offshore, catastrophic flooding from rainfall is a major independent risk — as Lane (2018) demonstrated.
Approaching hurricanes generate dangerous swells days before the storm arrives. Stay out of the ocean when any tropical cyclone is within 500 miles. Surge risk on low-lying coastal and leeward areas is significant.
Downed power lines on island topography can take weeks to restore in remote areas. A portable power station is strongly recommended. Never use a generator indoors — same rules apply as any hurricane.
Hawaii's Emergency Alert System and NOAA Weather Radio are your primary information sources once storm conditions develop. Know your local AM station that carries EAS alerts. Cell service may fail.
