Continued Wet Weather Raises Operational Risks for Island Businesses

·7 min read·👀 Watch

Executive Summary

Persistent wet weather and potential flash flooding across Hawaii pose immediate operational and supply chain risks for businesses, particularly on Maui and the Big Island. Operations should be reviewed for resilience over the next 7 days.

Watch & Prepare

High PriorityNext 7 days

The risk of flash flooding and continued high winds can lead to property damage, disrupt transportation and logistics, and impact business operations if not proactively managed.

Businesses should monitor the [National Weather Service Honolulu](https://www.weather.gov/hfo/) for updated flash flood watches and warnings. Specifically, watch for any sustained periods of high wind advisories (Tropical Storm Force or greater) or flash flood warnings in your immediate operational area. If these conditions persist for more than 24 hours or escalate beyond initial forecasts, trigger your business continuity plan, focusing on securing assets, protecting perishable inventory, and ensuring employee safety.

Continued Wet Weather Raises Operational Risks for Island Businesses

Persistent wet weather and the threat of flash flooding across Hawaii are increasing operational risks for businesses, especially on Maui and the Big Island. While the primary storm system has moved, ongoing atmospheric conditions necessitate a review of business continuity plans.

The Change

The Kona low system that impacted Hawaii has begun to move north, but forecast models indicate a continued threat of heavy rainfall and potential flash flooding for Maui County and Hawaii Island. Strong winds may also persist in parts of Oahu and Kauai through [March 16, 2026]. This prolonged period of unstable weather continues to strain infrastructure and disrupt normal business operations, with an estimated 49,000 residents still reporting power outages as of [March 15, 2026].

Who's Affected

Small Business Operators (small-operator):

  • Disruptions: Potential for temporary closures due to localized flooding or power outages. Supply chain disruptions for goods and perishable inventory are likely. Staffing challenges may arise if employees are unable to commute safely.
  • Costs: Increased costs due to potential spoilage, overtime pay for recovery, or temporary relocation if facilities are compromised.

Real Estate Owners (real-estate):

  • Property Damage: Risk of minor to moderate property damage from flooding, particularly in low-lying areas. Landlords should anticipate tenant requests for repairs and potential rent abatements.
  • Infrastructure Strain: Prolonged power outages could impact building systems (HVAC, elevators) managed by property owners and increase maintenance needs.

Tourism Operators (tourism-operator):

  • Activity Cancellations: Outdoor tours, beach activities, and inter-island travel may face cancellations or significant delays due to weather conditions, impacting revenue.
  • Guest Experience: Power outages and travel disruptions can negatively affect the guest experience, leading to potential complaints or reduced bookings.

Agriculture & Food Producers (agriculture):

  • Crop Damage: Heavy rainfall can lead to crop saturation, root rot, and potential loss, particularly for crops sensitive to waterlogged conditions.
  • Harvesting & Logistics: Delays in harvesting due to field conditions and disruptions in transportation can impact the timely delivery of produce to markets and processors.

Second-Order Effects

Continued power outages and transportation disruptions are likely to exacerbate existing supply chain vulnerabilities. For instance, delays in food distribution from farms to retailers can lead to increased spoilage, higher wholesale prices, and reduced availability for consumers. This, in turn, can put pressure on small business operators to absorb rising costs or pass them on, potentially impacting their margins and demand. Furthermore, prolonged disruptions can slow the recovery of affected agricultural land, impacting future yields and the overall food security on the islands.

What to Do

This weather pattern necessitates a proactive approach to risk mitigation over the next seven days. Businesses should monitor weather alerts and assess their operational resilience.

Small Business Operators:

  • Mitigation: Review inventory and implement flood protection measures for vulnerable stock. Ensure backup power solutions are functional if electricity is critical. Communicate potential disruptions to staff and customers.
  • Action: Review insurance policies for weather-related damage and business interruption clauses. Confirm with suppliers about their own continuity plans and potential impacts on delivery schedules.

Real Estate Owners:

  • Mitigation: Inspect properties for potential flood entry points and clear storm drains. Ensure critical building systems are operational or have backup plans.
  • Action: Communicate with tenants regarding weather preparedness and the schedule for any necessary repairs. Be prepared for potential increases in maintenance requests.

Tourism Operators:

  • Mitigation: Develop contingency plans for weather-related cancellations, including flexible rescheduling options and clear communication protocols for guests.
  • Action: Monitor inter-island flight and ferry schedules closely. Advise guests to allow for extra travel time and be prepared for itinerary adjustments.

Agriculture & Food Producers:

  • Mitigation: Assess field drainage and implement measures to protect high-value crops from waterlogging. Secure storage facilities against moisture damage.
  • Action: Coordinate with buyers and logistics providers to understand potential delays and adjust harvest schedules accordingly. Monitor crop health indicators for signs of stress or disease.

Action Details

Businesses should monitor the National Weather Service Honolulu for updated flash flood watches and warnings. Specifically, watch for any sustained periods of high wind advisories (Tropical Storm Force or greater) or flash flood warnings in your immediate operational area. If these conditions persist for more than 24 hours or escalate beyond initial forecasts, trigger your business continuity plan, focusing on securing assets, protecting perishable inventory, and ensuring employee safety.
