Key Points Leading up to the 2026-27 El Niño

Key Forecasting Principles & Winter Outlook

• Signal Strength vs. Certainty: We are highly confident a very strong El Niño will persist through the winter. However, very strong signals do not guarantee strong impacts everywhere. We are discussing a shift in probabilities, not a prediction of specific outcomes or certainties.
• Oceanic Signal & Atmospheric Response: The ocean is sending a strong climate signal, but the question is not whether El Niño exists. The key question is how efficiently the atmosphere will respond and convert that signal into local weather impacts favoring storm activity in Southern California.
• Climate Background vs. Weather Events: El Niño influences the background environment for the season, but it does not determine the timing, track, or intensity of individual storms. Elevated odds exist, but we cannot yet speak with confidence about specific storms, exact locations, or specific rainfall amounts.
• Actionable Operational Forecasting: There is a meaningful difference between a seasonal outlook (which describes risk) and an operational storm forecast (which describes what is expected to happen). The most actionable forecasts will come just days before an event, once storms move onto the horizon of predictability. Weather forecasting is a wide range of reasonable outcomes, not a binary choice between "nothing happens" and "disaster."
• Credibility & Messaging: We are careful not to overstate long-range risks, as maintaining credibility is critical for when high-confidence warnings become necessary. Right now, this winter is best described as having a noteworthy climate signal combined with substantial uncertainty about the details. Our messaging will evolve as the season unfolds and science provides greater certainty.

Kelvin Waves – Basics of “Water Slosh” with El Niño

• Sea level is higher near Southeast Asia during Neutral/Normal conditions as trade wind pile water up in the Western Pacific Ocean.
• During El Niño water comes sloshing back in underwater waves across the Pacific as trade wind break down or reverse (strong El Niño). These waves can refract and change direction, height and period.

City Departmental Preparations

• Continuous monitoring of weather forecasts
• Internal and external coordination for El Niño/winter storms
• Inspections of city facilities prior/after storms
• Pre-stage equipment and barriers for storm response
• Public information

Fire Department/OES

• Coordination with NWS, and County partners
• Public Information & Education
• Training & Exercises
• City Emergency Operations Plan (EOP)
• Upstaffing of Fire personnel:
  • Swift water/ocean rescue certified personnel
  • Additional apparatus including Type 3 engines
  • Visible presence and patrolling of hazard areas
• Emergency Operations Center (EOC) Activation (Level 1-3)

Police

• Continuous monitoring of weather forecasts and coordination with regional law enforcement and emergency management partners.
• Pre-event briefings with city departments, fire, public works, and utilities to ensure unified situational awareness.
• Increased staffing and readiness of patrol units during forecasted storm periods for rapid response.
• Pre-positioning of critical equipment such as barricades, high-clearance vehicles, and traffic control assets.
• Implementation of an emergency communications plan to push timely information to the public via Nixle, social media, and city platforms.
• Coordination with shelters and outreach teams to assist unhoused and vulnerable populations before and during storm impacts.
• Rapid response protocols for flooded roadways, downed power lines, traffic hazards, and evacuations.
• Assessment of flood-prone and landslide-risk areas to plan resource allocation and patrol deployment.
• Collaboration with Public Works on road closures, debris flow monitoring, evacuations, and real-time hazard updates.

Public Works - Drainage System Readiness (Citywide)

• Inspect drains, culverts, creeks, channels
• Perform recommended maintenance
• Coordinate with Creeks, Fire, Police, Parks
• Monitor forecasts; adjust operations

Public Works - Regional Coordination & Public Messaging

Waterfront

• Constructing defensive sand berms at Mission Creek and Harbor West Parking lot in October (earlier than usual).
• Removing catamaran sailboats off Leadbetter beach in October (earlier than usual)
• Preparing materials and equipment for potential closures of parking lots and other coastal areas that could be impacted by increased tide and swell events.
• Identifying dates and times of King High tides which increase risk of flooding and coastal damage. (Thanksgiving and Christmas King Tides)
• Notifying slip holders and anchorage users to prepare their vessels for winter.
• Stocking chain, materials, and equipment to secure marina docks during large swells.
• Preparing sandbags for Waterfront businesses and tenants.
• Preparing and clearing drainage systems in known areas of flooding within the Waterfront.

Sustainability & Resilience

• Working with Public Works and Santa Barbara County Flood Control District to inspect major creeks and remove hazardous downed trees and debris as needed.
• Operate and maintain tide gates at Andrée Clark Bird Refuge to minimize flooding.
• Conducting annual creek walks to remove trash and note creek changes and issues.
• Completing maintenance activities at restoration and water quality improvement project sites to remove hazardous debris and maintain drainage features
• Catch basin screen replacement and maintenance
• Work to move unhoused individuals and remove illegal dumped items within creek areas.
• Monitoring flooding and shoreline erosion changes over time.
• Contract with Marborg to provide debris removal services before, during, and after storm.
• Manage several long-term flood and erosion risk reduction projects at Waterfront, Laguna Creek, and Sycamore Creek.

Office of Housing and Community Vitality

• Freedom Warming Centers (operated by Good Samaritan Shelters)
  • Provides pop up shelter at the Unitarian Society November 15 through March 15
