A Potentially Historic El Niño Is Underway

A potentially historic El Niño is underway, and businesses have an opportunity to prepare before its effects are fully realized.  Forecasters indicate there is a greater than 90% chance the current event will reach very strong status this fall and winter, with some outlooks suggesting it could become one of the strongest El Niño events recorded since 1950.

While no one can predict exactly how weather patterns will develop across every region, organizations should understand how a major climate event can affect operations, supply chains, transportation networks and overall business resilience in the months ahead. Taking proactive steps now may help businesses reduce disruptions and better position themselves to respond if conditions intensify.

What Businesses Can Do Now

Whether this El Niño ultimately becomes the strongest on record remains to be seen. What is already clear is that many organizations have an opportunity to review preparedness measures before weather-related disruptions occur.

Organizations may want to consider the following actions:

  • Review business continuity and emergency response plans to ensure critical operations can continue during disruptive events.
  • Identify key suppliers, vendors and transportation partners that may be vulnerable to weather-related impacts.
  • Evaluate contingency plans and alternative sourcing options for critical goods and services.
  • Review backup power capabilities and confirm that critical equipment and operations can be supported during utility interruptions.
  • Assess potential vulnerabilities at facilities, including drainage systems, flood exposures, water intrusion risks and protection of critical equipment.
  • Verify emergency communication procedures for employees, customers and business partners.
  • Review inventory strategies and assess whether critical materials or equipment should be secured in advance of potential disruptions.
  • Monitor forecasts and seasonal outlooks from trusted sources such as NOAA, the National Weather Service and local emergency management agencies. 

Strong preparedness efforts are not about predicting exactly what will happen. They are about understanding where vulnerabilities exist and reducing the potential impact of unexpected events.

The Bottom Line

A potentially historic El Niño is no longer a future possibility. It is a developing climate event that forecasters expect to strengthen through the coming months, with some outlooks suggesting it could become one of the strongest El Niño events on record.

While the specific impacts will vary by region, history has shown that strong El Niño events can influence weather patterns, transportation systems, supply chains, utility reliability and business operations across multiple industries.

Organizations cannot control the forecast, but they can control how prepared they are to respond.

By reviewing continuity plans, assessing operational dependencies, evaluating supplier relationships and strengthening response procedures now, businesses can be better positioned to navigate disruptions if conditions intensify in the months ahead.
