Executive Summary

A severe weather system is forecast to impact the Hawaiian Islands within days, potentially disrupting supply chains, utilities, and transportation networks. Businesses must enact immediate contingency plans to mitigate operational losses and ensure employee safety.

  • Small Business Operators: Plan for potential closures, reduced foot traffic, and supply chain interruptions.
  • Real Estate Owners: Assess property vulnerability and prepare for potential damage.
  • Tourism Operators: Expect flight delays/cancellations and reduced visitor activity.
  • Agriculture & Food Producers: Secure crops and livestock, and prepare for transportation delays.
  • Healthcare Providers: Ensure staffing and resource availability for potential surge or access issues.
  • Action: Implement emergency preparedness protocols immediately.

Action Required

High PriorityImmediately

The weather event is expected within days, potentially impacting immediate operations, transportation, and employee safety if preparations are not made.

All impacted roles must immediately activate or develop emergency preparedness plans. This includes communicating with staff and customers, securing assets, verifying critical infrastructure (like backup power), and adjusting operations based on real-time weather advisories. For all sectors, monitoring official weather updates and coordinating with local emergency management agencies is crucial.

Imminent Severe Weather Threatens Operational Disruptions Across Hawaii Businesses

A severe weather system is forecast to impact the Hawaiian Islands starting late tomorrow and lingering through Wednesday, with potential for renewed activity later in the week. Forecasters anticipate prolonged periods of showers and strong winds, posing significant risks to infrastructure, supply chains, and business operations across all sectors.

The Change

The National Weather Service has issued advisories for potential high winds, heavy rainfall, and rough seas affecting the Hawaiian Islands beginning Tuesday night, March 11th, 2026, and continuing through at least Wednesday, March 12th. A lull is expected briefly on Thursday, March 13th, before weather conditions potentially worsen again. This system is characterized by its duration and the possibility of significant rainfall accumulation, increasing the risk of localized flooding, landslides, and power outages across the state. While specific intensities are still being refined, the forecast calls for conditions that could significantly hamper transportation, communication, and daily business activities.

Who's Affected

Small Business Operators (e.g., restaurants, retail, service providers):

  • Risk: Potential for mandatory or voluntary closures due to unsafe conditions or utility disruptions. Reduced foot traffic during the event. Supply chain disruptions leading to inventory shortages and increased costs. Staffing challenges as employees may be unable to commute safely.
  • Impact: Direct revenue loss during closures, increased operational costs for protective measures, potential spoilage of perishable goods.

Real Estate Owners (property owners, landlords, property managers):

  • Risk: Increased risk of property damage from high winds, heavy rain, and potential flooding. Power outages affecting tenant services. Access issues for maintenance and repair.
  • Impact: Costs associated with repairs, potential loss of rental income if properties are uninhabitable, increased insurance claims.

Tourism Operators (hotels, tour companies, vacation rentals):

  • Risk: Flight delays and cancellations due to weather impacting visitor arrivals and departures. Reduced demand for tours and activities. Potential cancellations of bookings leading to revenue loss. Staffing difficulties if employees cannot travel to work.
  • Impact: Significant revenue reduction, reputational damage if unable to provide services, increased costs for managing cancellations and rebookings.

Agriculture & Food Producers (farmers, ranchers, food processors):

  • Risk: Crop damage from high winds and heavy rain. Livestock endangerment. Disruption of harvest and transportation logistics. Potential for localized flooding impacting fields and facilities.
  • Impact: Loss of yield, increased costs for protective measures and recovery, delayed market supply, potential spoilage of produce.

Healthcare Providers (clinics, hospitals, private practices):

  • Risk: Staffing shortages if employees cannot commute. Increased demand for emergency services due to weather-related incidents. Utility disruptions impacting critical equipment. Telehealth service interruptions due to internet connectivity issues.
  • Impact: Strain on resources, disruption to patient care, potential inability to reach facilities, emergency preparedness costs.

Second-Order Effects

Consecutive days of severe weather can cascade through Hawaii's isolated economy. Short-term disruptions to transportation and logistics (shipping, trucking, air cargo) can quickly lead to inventory shortages. This strain on supply chains will increase costs for businesses, particularly for imported goods, which are already subject to the Jones Act. These higher operating costs for businesses, especially in the food and retail sectors, may necessitate price increases for consumers, contributing to inflation and potentially reducing discretionary spending. For tourism operators, prolonged disruptions could lead to cancellations, impacting revenue and subsequent spending on local services. Furthermore, widespread power outages can cripple businesses reliant on digital infrastructure and climate control, further exacerbating economic losses and impacting remote worker productivity.

What to Do

Small Business Operators:

  • Immediate Action: Review and activate your emergency preparedness plan. Secure outdoor assets, monitor weather advisories closely, and communicate operational status and potential disruptions to staff and customers. Consider stocking essential supplies for your business and employees, and verify backup power options if applicable.
  • Timeline: Implement protocols immediately. Decision to close should be made 12-24 hours in advance of predicted severe impact.

Real Estate Owners:

  • Immediate Action: Conduct a pre-weather inspection of properties, focusing on drainage systems, roofs, and windows. Secure loose items on property premises. Ensure tenants are informed of emergency procedures and contact information. For commercial properties, review contingency plans for essential services.
  • Timeline: Inspections and securing measures should be completed by tomorrow evening.

Tourism Operators:

  • Immediate Action: Proactively contact guests regarding potential travel disruptions. Monitor airline and travel advisories closely. Adjust staffing schedules to account for potential commute difficulties. Review cancellation and rebooking policies to ensure client service during disruptions.
  • Timeline: Begin customer notifications and policy reviews immediately.

Agriculture & Food Producers:

  • Immediate Action: Secure crops and livestock. Inspect and reinforce shelters and irrigation systems. Prepare harvest plans to salvage ready crops if conditions allow before the worst weather hits. Contingency planning for transportation delays for both incoming supplies and outgoing produce is critical.
  • Timeline: Take protective actions for crops and livestock before tomorrow night.

Healthcare Providers:

  • Immediate Action: Activate emergency staffing plans and ensure adequate on-call protocols are in place. Verify the operational status of backup generators and critical medical equipment. Confirm emergency communication channels for staff and patients, especially for telehealth services. Review supply chain for critical medical items that may be affected by transportation delays.
  • Timeline: Emergency protocols and staffing plans should be in effect by tomorrow morning.
