Hawaii faces a fast-moving preparation window as Lala approaches the Big Island and is expected to strengthen. Forecast hazards reach beyond the storm’s center, with heavy rain and surf potentially affecting multiple islands.
A hurricane warning has been issued for Hawaii County as Tropical Storm Lala approaches the Big Island of Hawaii and is forecast by the National Hurricane Center to strengthen into a hurricane. The storm could bring as much as two feet of rain and sustained winds of 75 mph near Hawaii from Friday night, August 14, 2026, into Saturday, August 15.
Lala’s center may pass near or south of the Big Island, but the threat is much wider than one forecast line on a map. Heavy rain, flash flooding, damaging wind and dangerous surf could affect communities across Hawaii as the system moves west-northwest.
Lala’s warning signals a narrow window
A hurricane warning means hurricane conditions are expected within 36 hours. That is a more urgent designation than a hurricane watch, which means hurricane-force winds are possible in the forecast area.
CNN reported that the warning was issued as Lala took aim at Hawaii. Forecast information cited by USA Today said the National Hurricane Center expected the system to become a Category 1 hurricane as it approached the Big Island.
The timing matters because tropical-storm-force winds could begin reaching the Big Island early Saturday. Those winds were forecast to spread toward Maui later Saturday, then reach Oahu late Saturday night into Sunday morning.
Storm forecasts can shift, especially when a system remains over open water. But officials’ message has been consistent: residents should not wait for a final track adjustment before taking basic preparation steps.
The rain threat may be the biggest risk
The National Hurricane Center forecast calls for exceptionally heavy rain on parts of the Big Island, particularly windward slopes. Some locations could receive up to 25 inches, while the broader headline forecast has warned of as much as two feet of rain.
That kind of rainfall can rapidly change conditions on steep terrain and in stream corridors. Fast-rising water, flash flooding, mudslides and blocked roads can become hazards even in places that do not receive the storm’s strongest winds.
Other islands farther west could receive 2 to 4 inches of rain, with isolated totals as high as 8 inches, according to the forecast. Those lower totals do not eliminate the flooding concern, particularly where rain falls in a short period or drains into already swollen streams.
Hawaii County Civil Defense urged Big Island residents to prepare for flooding rains, high surf and damaging winds. The agency advised people to have food, water and fuel available and to sign up for emergency alerts.
Winds could extend far from center
Forecasts called for Lala to reach sustained winds of about 75 mph, with higher gusts, as it neared Hawaii. Hurricane-force winds begin at 74 mph, meaning even a relatively low-end hurricane can damage roofs, trees, power lines and unsecured outdoor property.
National Hurricane Center Director Michael Brennan cautioned that people should not concentrate only on the exact forecast path of Lala’s center. Winds and heavy rain can spread well away from the core of a tropical cyclone.
That is especially important for Hawaii’s islands, where local terrain can intensify rainfall and create sharp differences in wind exposure from one neighborhood to another. A forecast track south of the Big Island does not mean the island’s northern or eastern areas are free from serious impacts.
As of the earlier forecast cited by USA Today, the chance of hurricane-force winds on the south side of the Big Island was 10% or less. That probability was not a guarantee of safety; it reflected both uncertainty in the exact track and the possibility that the strongest winds could stay concentrated elsewhere.
Surf and coastal flooding add danger
Lala is also expected to send a large easterly swell toward the islands. Surf was forecast to build first along east-facing shores, moving from east to west as the system approaches.
Waves of 15 feet or higher are possible through the weekend, according to the National Hurricane Center forecast. Prolonged high surf can cause coastal flooding, beach erosion and dangerous ocean conditions long before — or after — the closest approach of a storm’s center.
Kauai County warned that river crossings, trails and outdoor recreation areas can become hazardous quickly during severe weather. The county said emergency rescues may not be possible in dangerous conditions and cautioned people not to cross swollen streams.
The surf risk also complicates preparation. Residents and visitors may be tempted to watch large waves, but shorebreak, rogue waves and changing currents can make exposed coastlines hazardous even when skies briefly appear calm.
Officials stress preparation, not panic
Honolulu Mayor Rick Blangiardi said Oahu residents should use the available time to prepare rather than panic. He urged households to check emergency supplies, make a family plan, secure property and stay informed as forecasts evolve.
Honolulu officials also warned that gusty conditions ahead of Lala could increase wildfire risk on Oahu. Securing loose objects and avoiding activities that could spark a fire are practical measures before stronger winds arrive.
- Keep enough drinking water, food, medications and essential supplies for several days.
- Charge phones and backup batteries before winds or outages begin.
- Secure outdoor furniture, trash bins and other items that can become airborne.
- Avoid beaches, stream crossings and flood-prone roads when conditions worsen.
- Follow official Hawaii County, county emergency-management and National Weather Service alerts for local instructions.
Preparation needs vary by household, particularly for people with medical needs, pets, limited transportation or homes in flood- and coastal-risk areas. The key issue is acting while travel and supply access remain routine.
The exact path remains uncertain
Forecasters expected Lala’s center to pass near or just south of the Big Island, but the track forecast carried a margin of error of roughly 50 to 60 miles at 48 hours before landfall. For a compact island geography, that is a consequential difference.
A shift in either direction could change which communities see the most severe wind, while rain and surf impacts may remain widespread regardless. That is why the forecast has emphasized hazards over a single point on the map.
A hurricane hunter aircraft flew into Lala to help meteorologists assess its structure and intensity. Those observations can improve forecasts, but they cannot remove all uncertainty around rapid strengthening, rainfall placement or localized wind effects.
The clearest takeaway is that Hawaii’s risk is not limited to whether Lala makes a direct hit. With a hurricane warning in place for Hawaii County and impacts expected to begin Friday night, residents across the islands have reason to follow official updates and complete preparations before conditions deteriorate.
