Incoming storm systems, coastal flooding, wind damage and extreme cold in the Bay Area

The Bay Area is currently experiencing a significant multi-hazard weather event, with forecasts predicting ongoing heavy rain, damaging winds, coastal flooding, and a sharp drop in temperatures inland. These conditions are causing widespread impacts across the region, demanding heightened preparedness and vigilance from residents and officials alike.

Forecasts and Advisories for Rain, Wind, Flooding, and Cold

The National Weather Service (NWS) has issued multiple advisories due to the overlapping storm systems. A Coastal Flood Advisory remains in effect for shoreline communities such as Pacifica and Sausalito, which are experiencing minor to moderate flooding during high tides, leading to shoreline erosion and property risks. Additionally, a Flood Advisory is in place for San Francisco County, where low-lying neighborhoods are inundated, prompting evacuations and emergency responses.

Marine conditions are hazardous, with a Small Craft Advisory issued across San Francisco Bay and surrounding channels. Strong winds and rough seas have made marine traffic dangerous, with authorities urging boaters to stay ashore. Widespread rainfall continues to cause flash flooding and rising water levels in North Bay communities, disrupting transportation and damaging infrastructure.

On-the-ground impacts include numerous downed trees, especially in San Francisco and Walnut Creek, where fierce winds have caused debris to block roads and topple power lines. Utility crews are working tirelessly to restore outages caused by fallen trees and lightning strikes—such as a recent incident in Walnut Creek where a lightning strike caused a large tree to fall onto power lines, resulting in localized outages. The storm's persistent nature has overwhelmed drainage systems, leading to standing water on streets and impassable routes, complicating emergency response efforts.

Infrastructure challenges are evident with the closure of Pacifica Pier, which remains shut through February 18, 2026, due to safety concerns during storm surges. Shoreline erosion risks continue to grow in Sausalito and Pacifica, prompting officials and residents to monitor tide levels closely during peak high tides. Transportation remains hampered by flooded roads and storm damage, with residents advised to avoid hazardous areas.

Extreme Cold and Mountain Hazards

In a surprising development, inland Bay Area regions are under an extreme cold warning, with temperatures plummeting into the mid-20s Fahrenheit overnight. This sudden cold snap increases risks of frostbite and hypothermia, particularly for outdoor workers and vulnerable populations. Power grids are under additional stress, and residents are urged to ensure proper heating and safety measures.

Adding to regional concerns, recent avalanche incidents near Lake Tahoe have resulted in multiple fatalities, including residents and outdoor enthusiasts. These avalanches are believed to be worsened by snow drought conditions, which destabilize snowpack and increase avalanche risk. Community mourning continues as families pay tribute to those lost, and authorities emphasize mountain safety and hazard awareness.

Community Response and Resilience

Amid these challenges, community-led initiatives are crucial. Social media campaigns by local scientists and outreach programs are promoting disaster preparedness, emphasizing securing property and creating emergency kits. UC Berkeley students are developing innovative solutions like fire-resistant landscaping and hazard reporting apps to enhance community resilience.

Current Status and Recommendations

The storm systems are expected to persist through the weekend, with heavy rain, strong winds, coastal flooding, and inland cold temperatures continuing to threaten safety and infrastructure. Residents are advised to:

• Stay informed through official weather updates and alerts.
• Secure property—reinforce windows, clear gutters, and elevate valuables.
• Avoid flooded roads, shoreline zones, and storm-damaged infrastructure.
• Participate in preparedness activities and review multi-hazard safety plans.
• Keep emergency supplies current and accessible.

Broader Outlook

This convergence of severe weather, seismic activity, and extreme cold highlights the importance of integrated disaster preparedness strategies in the Bay Area. Understanding mountain hazards, especially in the context of climate variability and snow droughts, is vital for public safety. The region’s collective response—driven by authorities, scientists, and resilient communities—is essential to mitigating risks and safeguarding lives during these complex, overlapping crises.

In summary, the Bay Area faces a challenging weekend with ongoing storms, coastal flooding, and cold inland temperatures. Continuous vigilance, community engagement, and proactive measures are critical to navigating these hazards and building long-term resilience.
