Molokaʻi & Maui Operations Face Potential Disruption from Heavy Rainfall; Big Island Summits Warned of Winter Storm Conditions

·4 min read·👀 Watch

Executive Summary

Immediate operational risks for Molokaʻi and Maui businesses due to flood warnings, while Big Island summit operations face winter storm hazards. Monitor weather alerts closely for supply chain and staffing impacts.

  • Small Business Operators: Assess supply chain fragility and employee commute safety.
  • Real Estate Owners: Review property drainage and access routes; check summit infrastructure.
  • Tourism Operators: Prepare for potential flight/tour cancellations and customer accommodation issues.
  • Agriculture & Food Producers: Secure perishable goods and monitor infrastructure for flood/snow damage.

Watch & Prepare

High Priority

Ignoring these warnings can lead to supply chain disruptions, employee safety issues, property damage, and power outages impacting business operations.

Monitor official weather alerts from the National Weather Service Honolulu (NWS Honolulu) and local county civil defense agencies. If flood warnings are extended or upgraded on Molokaʻi or Maui, or if winter storm conditions impact transportation routes on the Big Island, trigger contingency plans for staff safety, supply chain rerouting, and customer communication. For agriculture, monitor critical infrastructure like irrigation and storage for damage. For tourism, actively communicate with guests about potential tour cancellations or advisories.

Immediate Operational Risks: Flood Warnings on Molokaʻi & Maui, Winter Storm Warning for Big Island Summits

As of Sunday afternoon, March 22, 2026, a kona low-pressure system has drawn significant moisture towards the Hawaiian Islands, prompting immediate weather advisories that demand business continuity planning. Molokaʻi is under a Flood Warning until 8:30 AM HST Monday, signaling a high probability of heavy rainfall leading to hazardous conditions on the island. Maui County is under a Flood Watch until 6:00 PM HST Monday, indicating potential for flash flooding. Concurrently, the summits of the Big Island are under a Winter Storm Warning, with expectations of heavy snow and potential blizzard conditions.

These conditions, driven by abundant moisture and a favorable low-pressure system, translate to direct operational challenges across multiple sectors. The immediate concern is the disruption to ground transportation, potential power outages, and the safety of staff and customers. Businesses must assess their vulnerability to these immediate weather events.
