Hurricane Nolo is threatening Hawaii with heavy rain, dangerous surf, high winds and flooding risks weeks after Hurricane Lala damaged the islands.
Overview
Nolo approached Hawaii as a tropical system south of the Big Island and was forecast to strengthen into a major hurricane. Watches covered the Big Island and other islands as forecasts called for 15 to 35 inches of rain and possible catastrophic flooding and mudslides. The storm later strengthened to Category 4 with sustained winds near 145 mph while remaining offshore and affecting the islands with rain, surf and wind hazards.
Why it matters
The storm threatens residents, travelers, infrastructure and emergency responders in Hawaii, especially where flooding, mudslides and water-system contamination risks were highlighted.
How it could play out
Loading where this could go
Key details
• Forecast rainfall ranged from 15 to 35 inches.
• Nolo strengthened to Category 4 with winds around 145 mph.
• The center remained offshore in the latest evidence.
• Winds were expected to carry tephra from Kīlauea that could block roads and contaminate rainwater catchment systems.
Keeping an eye on this saga?
Tilt can alert you when its scenarios shift, or send you a recommendation when one crosses a threshold.
Nolo comes ashore on or very near the Big Island while still a strong hurricane, producing destructive winds, flash flooding, landslides, and extended power outages. The repeated hit after Lala strains local emergency capacity and pushes insurers, banks, utilities, airlines, and tourism operators into immediate loss-assessment mode.
Nolo avoids a direct landfall but tracks close enough to keep the Big Island under persistent rain bands and tropical-storm-force winds. This outcome reduces wind damage compared with a direct hit but still creates dangerous flooding and multi-day travel disruption.
Nolo turns away before delivering its forecast worst-case hit, allowing officials to downgrade warnings and reopen transport links quickly. Because markets had begun pricing a costly repeat disaster after Lala, this scenario produces a modest relief rally in Hawaii-linked equities and travel exposure.
Instead of moving cleanly past the Big Island, Nolo’s path brings damaging rain, high surf, and transport disruption across multiple Hawaiian islands. The market impact broadens from a Big Island event to a statewide tourism, shipping, utility, and banking concern.
