El Niño 101: What Every Resilient Business Should Know

A major climate shift may be on the horizon. According to AccuWeather, conditions are aligning for a potential El Niño to develop in 2026—bringing with it widespread and often unpredictable impacts across the United States.

What is El Niño?

El Niño is part of a larger climate pattern driven by warming ocean temperatures in the Pacific. As those temperatures rise, they disrupt global weather systems—shifting storm tracks, altering precipitation patterns, and increasing volatility across regions.

What Could El Niño Mean for the U.S.?

If El Niño develops, businesses should prepare for less predictable and more uneven weather impacts, including:

• Shifts in storm patterns and severity
• Potential suppression of Atlantic hurricanes—but not elimination of risk
• Increased rainfall and flooding in some regions
• Drought and prolonged heat in others
• Peak impacts building into late 2026 and early 2027

The key takeaway: this is not a “one-risk” scenario—it’s a volatility scenario.

What El Niño Means for Business Continuity

El Niño challenges a common assumption in resilience planning: that risk follows predictable seasonal patterns. Instead, organizations may face simultaneous or unexpected disruptions—from flooding and power outages to supply chain delays and workforce displacement.

Resilient businesses don’t try to predict every outcome—they prepare across core operational dependencies:

How to Prepare for El Niño: 5 Pillars of Resilience

1. Power: Plan for Outages—Not Possibilities

Severe storms, grid strain, and extreme heat all increase the likelihood of outages.

Recommendations:

• Secure backup power solutions (generators, fuel supply)
• Test failover capabilities before peak storm season
• Identify critical systems that must remain operational

2. Connectivity: Stay Online When Infrastructure Fails

Connectivity disruptions—whether from fiber cuts, network outages, or infrastructure damage—can halt operations instantly.

Recommendations:

• Establish redundant connectivity (LTE, satellite, or secondary providers)
• Ensure remote access to critical systems and data
• Validate network failover through regular testing

3. Communications: Control the Narrative Before and After the Storm

Clear, timely communication is essential to maintaining trust and reducing confusion.

Pre-event:

• Define communication protocols and escalation paths
• Segment audiences (employees, customers, stakeholders)
• Pre-draft messages for likely scenarios

Post-event:

• Provide real-time updates on operational status
• Share recovery timelines and next steps
• Maintain consistent messaging across all channels

Tools matter: Platforms like MyAgility enable organizations to send targeted email and SMS alerts to specific groups—ensuring the right people get the right information at the right time.

4. Workspace: Ensure Operations Continue—Anywhere

Flooding, storm damage, or unsafe conditions can make primary facilities unusable.

Recommendations:

• Pre-arrange alternate workspace solutions (mobile offices, recovery centers)
• Enable remote work capabilities with secure access
• Identify critical roles that require physical space vs. remote flexibility

5. People: Turn Plans into Action Through Practice

Even the best plan fails if teams don’t know how to execute it.

Recommendations:

• Conduct regular tabletop exercises (2–4 times per year)
• Simulate a range of scenarios—not just one type of disruption
• Clarify roles, responsibilities, and chain of command
• Identify gaps in decision-making, communication, and response time

Tabletop exercises ensure your team doesn’t just have a plan—they can execute it under pressure.

Resilience is the Advantage

El Niño is a powerful reminder that disruption doesn’t follow a script. As climate patterns shift, so do the risks businesses face.

The organizations that come out ahead won’t be the ones who guessed right—they’ll be the ones who prepared across every critical dependency: power, connectivity, communications, workspace, and people.

Because when volatility increases, resilience becomes a competitive advantage.
