San Diego Gears Up for Major Travel Disruptions as Pineapple Express Storm Hits on Christmas Eve, Threatening Flooding and Airport Chaos for Holiday Travelers!

Published on December 20, 2025

San Diego, California is on high alert as a powerful atmospheric river, known as the Pineapple Express, heads toward the region, bringing significant rainfall and flooding risks right before Christmas Eve. The storm, which is expected to deliver up to two inches of rain, has raised concerns about travel disruptions, especially for the holiday season when millions of travelers are expected to crowd the roads and airports. Areas such as Fashion Valley in Mission Valley, notorious for flooding, are particularly vulnerable to the storm’s impacts. As the storm intensifies, city officials, local utilities, and emergency services are on full alert to minimize damage and help residents and visitors stay safe during the busy travel period.

Introduction: San Diego Faces Holiday Travel Chaos as Pineapple Express Storm Approaches

San Diego is no stranger to unpredictable weather, but the Christmas Eve storm currently barreling toward the region has the potential to bring the city to a halt. The Pineapple Express, a type of atmospheric river, draws moisture from the tropics and unleashes it on the West Coast, often resulting in heavy rainfall, flash floods, and dangerous travel conditions. This weekend storm could dump up to two inches of rain on coastal areas, with even higher rainfall amounts expected inland. The National Weather Service is forecasting that these conditions could disrupt holiday travel, particularly for those heading to San Diego International Airport and the surrounding areas.

As the holiday season kicks into full swing, the storm’s timing couldn’t be worse. With millions of people traveling through Southern California for the Christmas holidays, the heavy rain is expected to create hazardous conditions on the roads and potentially cause delays at one of the busiest airports in the country. San Diego International Airport, which will see upwards of 85,000 passengers on Tuesday, one of the busiest travel days of the year, is already gearing up for potential delays and cancellations. The storm’s effects are anticipated to stretch far beyond the airport, affecting traffic on the I-5, I-805, and I-15 corridors, the main highways leading to and from the city.

AAA estimates that over 10 million people will be traveling through Southern California during the holiday period, representing a 2% increase from the previous year. This surge in travel, combined with the storm’s expected intensity, could leave thousands of vehicles stranded on local roadways. AAA has already warned drivers to expect delays and is urging them to take necessary precautions such as leaving more space between vehicles, checking tire pressure, and ensuring that cars are in good working condition before hitting the road.

In addition to concerns about travel disruptions, flooding remains one of the most pressing issues for San Diego. The city is monitoring more than 46,000 storm drains, which will be critical in preventing water from backing up and causing localized flooding. With areas like Fashion Valley Mall and Mission Valley particularly vulnerable to rising river levels, the city has mobilized flood mitigation efforts to keep streets clear and prevent property damage.

Despite these challenges, the storm’s impact could have some positive effects as well. Fire officials are hopeful that the rains will help mitigate the region’s fire danger, which had been a persistent concern during the dry months. As temperatures cool and the ground becomes saturated, the fire risk will decrease, at least for the coming month.

Key Impacts of the Pineapple Express Storm on San Diego’s Travel and Safety

As the Pineapple Express storm moves closer, here’s a breakdown of what San Diego can expect in terms of weather impacts, travel disruptions, and public safety efforts.

1. Heavy Rainfall and Flood Risks in San Diego County

• The Pineapple Express storm is expected to dump one to two inches of rain at the coast, with higher amounts in inland areas.
• Areas such as Fashion Valley in Mission Valley are particularly vulnerable to flooding, as heavy rains could swell the San Diego River and lead to flooded streets and shopping areas.
• City officials are monitoring flood risks closely and have already cleared channels and storm drains in flood-prone areas.

2. Disruptions at San Diego International Airport

• San Diego International Airport is expecting 85,000 passengers on the busiest travel day of the year, and the storm’s arrival may lead to delays and cancellations.
• Travelers should check flight statuses frequently, as the heavy rain and wind may affect airport operations, including security wait times and boarding procedures.
• The storm could also result in crowded terminals as travelers seek shelter from the rain, increasing the likelihood of long lines and delays.

3. Road Travel Hazards and AAA Warnings

• With 10 million travelers expected in Southern California, the storm’s impact on road conditions will be significant. AAA anticipates 200,000 calls for stranded vehicles, with dead batteries, flat tires, and running out of gas being the primary causes.
• The I-5, I-805, and I-15 highways are expected to experience heavy congestion and slow-moving traffic. Drivers are urged to slow down, leave extra space between vehicles, and avoid distractions while driving in wet conditions.

4. Public Safety and Flood Prevention Efforts

• City officials have cleared more than 46,000 storm drains and flood channels to reduce the risk of localized flooding. Residents have been asked to help by clearing debris from drains near their homes.
• San Diego Gas & Electric (SDG&E) is preparing for potential power outages, particularly as wet weather increases the risk of vehicle accidents involving power poles and transformers.
• In addition, the utility company will have crews on standby around the clock to address any outages quickly.

How to Prepare for the Pineapple Express Storm in San Diego

With the storm fast approaching, residents and travelers alike are advised to take the following steps to ensure their safety during the holiday season.

1. Stay Informed About Weather and Travel Conditions

• Keep an eye on local weather reports and road conditions via apps and the San Diego County website to receive real-time updates.
• Check your flight status at San Diego International Airport before heading out to ensure there are no delays or cancellations due to weather.

2. Secure Your Home and Vehicle

• Ensure that storm drains near your home are clear of debris to help prevent flooding.
• If you’re traveling by car, make sure your vehicle is roadworthy, with adequate tire pressure, full windshield wiper fluid, and a charged battery.

3. Plan for Delays and Longer Travel Times

• Be prepared for increased traffic congestion, especially near San Diego International Airport, Mission Valley, and other busy areas.
• Allow extra time for airport security, as the storm is likely to slow down airport procedures.

4. Prepare for Possible Power Outages

• If the power goes out, use flashlights instead of candles, and ensure that your devices are charged before the storm hits. Avoid downed power lines and report them to SDG&E immediately.

The Positive Side of the Pineapple Express Storm: Reduced Fire Danger

While the storm brings a host of challenges, it could help reduce fire danger in the region. Fire officials have expressed relief that the rain will significantly saturate the ground, preventing the wildfire risk that has plagued the region during the dry months. The cooler temperatures brought by the storm will also provide a much-needed break from the heat, which has been a major concern for local residents and tourists.

Conclusion: Preparing for San Diego’s Holiday Storm

As San Diego braces for the upcoming Pineapple Express storm, residents and travelers alike are urged to prepare for heavy rain, flood risks, and travel disruptions. While the storm poses challenges for the holiday travel season, proactive efforts from city officials, utility companies, and emergency services are in place to mitigate the impact on the public. By staying informed, taking necessary precautions, and planning for potential delays, everyone can help ensure their safety during this significant weather event.
