Hurricane Nolo may bring repeat flooding to Hawaii's Big Island
Hurricane Nolo is skirting Hawaii's Big Island, with forecasts calling for 20 to 30 inches of rain, though the storm may not bring hurricane-force winds. Five weeks ago, Hurricane Lala dumped feet of rain on the island, causing locally disastrous flooding, and a similar situation now appears likely to repeat. On Thursday, Nolo was then a tropical storm in the Pacific Ocean, west of the U.S. and Mexico coastlines, alongside Hurricanes Odalys and Polo.

- Forecast calls for 20 to 30 inches of rain as Hurricane Nolo skirts Hawaii's Big Island. — Figure appears in source but no forecasting agency is named; unattributed.
- The storm may not bring hurricane-force winds to the island. — Stated in source as forecast expectation, no source given.
- Hurricane Lala dumped feet of rain on the Big Island five weeks earlier, causing locally disastrous flooding. — Presented as background fact in source; no agency or damage figures attributed.
- Nolo, then a tropical storm, was in the Pacific with Hurricanes Odalys and Polo west of the U.S. and Mexico coastlines on Thursday. — Described in source as an image caption detail; internally consistent with Nolo later being a hurricane.
Analysts’ view opinion
Politically, the story here is repetition: a second major rain event on the Big Island within five weeks turns a weather story into a governance test. Voters generally forgive the first storm and judge the response to the second, so Hawaii's state and county officials — and the federal agencies backing them — will be measured on whether lessons from Hurricane Lala were actually applied. The forecast of 20 to 30 inches with sub-hurricane winds also creates a communication trap: if the wind emphasis reassures people into complacency and flooding still hits hard, the blame conversation shifts quickly from nature to warnings and preparedness.
- Back-to-back events compress the political timeline — officials get credit for visible pre-positioning and criticism for anything that looks like a repeat of unresolved problems.
- The 'no hurricane-force winds' framing is a messaging risk, because rainfall and flooding, not wind, appear to be the main hazard in this forecast.
- Recovery from the earlier storm becomes a live political issue: any areas still unrepaired will be read as evidence of slow follow-through, though the story does not detail that recovery's status.
- Federal-state coordination is the usual flashpoint after repeat disasters, with disaster declarations and aid speed the most politically visible variables.
- Repeated Pacific storm activity tends to strengthen arguments for climate resilience and infrastructure spending, while opponents typically counter that single seasons should not drive long-term budget commitments.
What to watch — Watch how quickly emergency declarations, evacuation guidance and aid requests move, and whether officials frame this as flood risk rather than wind risk in their public messaging.
The story establishes only the forecast and the recent precedent — it says nothing about the actual damage, the state of recovery from the earlier storm, or any official political response.

Context
Hawaii's Big Island is facing the prospect of a second extreme rainfall event in little over a month. Five weeks after Hurricane Lala dumped feet of rain on the island and triggered locally disastrous flooding, Hurricane Nolo is now skirting the island. Forecasters expect 20 to 30 inches of rain, even though the storm may not deliver hurricane-force winds to land. Nolo is one of several simultaneous systems in the Pacific, along with Hurricanes Odalys and Polo.
Key facts
- Forecasts for Hurricane Nolo call for 20 to 30 inches of rain as it skirts Hawaii's Big Island.
- The storm may not bring hurricane-force winds, making rainfall the primary hazard.
- Hurricane Lala dumped feet of rain on the Big Island five weeks earlier, causing locally disastrous flooding.
- Forecasters say a repeat of the Lala flooding scenario looks likely with Nolo.
- On Thursday, Nolo was still a tropical storm, located in the Pacific Ocean west of the U.S. and Mexico coastlines.
- Nolo was then accompanied in the Pacific by two other systems: Hurricanes Odalys and Polo.
- The report is dated September 25, 2026, at 11:35 a.m. EDT.
Timeline
- About five weeks before September 25, 2026Hurricane Lala dumps feet of rain on Hawaii's Big Island, leading to locally disastrous flooding.
- Thursday (before September 25, 2026)Nolo is a tropical storm in the Pacific, west of the U.S. and Mexico coastlines, alongside Hurricanes Odalys and Polo.
- September 25, 2026Nolo, now a hurricane, skirts the Big Island with 20 to 30 inches of rain forecast; a repeat of Lala-style flooding appears likely.
Who has a stake
- Residents of Hawaii's Big Island — Face a second extreme rainfall and flooding event within five weeks, with 20 to 30 inches of rain forecast.
- Weather forecasters and warning agencies — Must communicate that the main threat is rainfall and flooding rather than hurricane-force winds.
- Local emergency and disaster response services — Responding to repeat flooding in areas still recovering from Hurricane Lala's impacts.
- Shipping and coastal interests in the eastern/central Pacific — Three systems active at once — Nolo, Odalys and Polo — west of the U.S. and Mexico coastlines.
Why it matters
A storm need not make landfall with hurricane-force winds to be destructive; rainfall of 20 to 30 inches can cause disastrous flooding on its own. Back-to-back events like Lala and Nolo strike communities before they have recovered, compounding damage and stretching relief capacity. The presence of three named Pacific systems at once also highlights how clustered tropical activity tests forecasting and warning systems.
UPSC angle
Prelims pointers
- Hurricane Nolo: forecast of 20 to 30 inches of rain over Hawaii's Big Island, without necessarily bringing hurricane-force winds.
- Hurricane Lala hit Hawaii's Big Island five weeks before Nolo, causing locally disastrous flooding.
- Nolo was a tropical storm on Thursday before intensifying into a hurricane.
- Hurricanes Odalys and Polo were simultaneously active in the Pacific west of the U.S. and Mexico coasts.
- Tropical cyclones in the Atlantic and eastern/central Pacific are called 'hurricanes'.
- Report dated September 25, 2026 — peak tropical cyclone season in the Pacific basin.
Mains framing
The Nolo–Hawaii episode illustrates that the destructive potential of a tropical cyclone is not captured by wind speed alone. The source notes that Nolo may not deliver hurricane-force winds, yet the forecast of 20 to 30 inches of rain makes flooding the dominant risk — the same mechanism by which Hurricane Lala caused locally disastrous flooding on the Big Island five weeks earlier. Two features compound vulnerability: recurrence, as a second extreme rainfall event arrives before recovery from the first is complete, and clustering, with Nolo, Odalys and Polo active simultaneously in the Pacific, dividing forecasting and response attention. The way forward, on the evidence in the source, lies in warning systems and public messaging that foreground rainfall and flood thresholds rather than category-based wind classification, and in anticipating that the same terrain can be hit repeatedly within a single season. Beyond this, the source does not state mitigation or policy measures.
Key terms
- Hurricane
- The name given to a strong tropical cyclone in the Atlantic and eastern/central Pacific; Nolo, Lala, Odalys and Polo are named examples in the source.
- Tropical storm
- A tropical cyclone weaker than a hurricane; Nolo was at this stage on Thursday before strengthening.
- Hurricane-force winds
- The high wind speeds associated with hurricanes, which the source says Nolo may not bring to the Big Island.
- Big Island (Hawaii)
- The Hawaiian island hit by Hurricane Lala's feet of rain and now in Hurricane Nolo's path.
- Hurricane Lala
- The storm that dumped feet of rain on Hawaii's Big Island five weeks earlier, causing locally disastrous flooding.
Practice questions
- Why can a tropical cyclone without hurricane-force winds still cause disastrous damage? Discuss with reference to the forecast for Hurricane Nolo over Hawaii's Big Island.
- Examine the challenges posed to disaster response when the same region is struck by two extreme rainfall events within a few weeks, as with Hurricanes Lala and Nolo.
- What are the implications of multiple simultaneous tropical cyclones — such as Nolo, Odalys and Polo — for forecasting and early warning systems?
