Atmospheric rivers are long, narrow streams of moisture that can stretch for thousands of miles and bring heavy rainfall to the American West. In areas affected by wildfires, these events can increase the risk of landslides, as seen in the Feather River Canyon following the 2021 Dixie Fire. Without vegetation, raindrops have a stronger impact on the soil, leading to increased landslide activity.
Experts like Nina Oakley and Kristen Guirguis are studying the interactions between atmospheric rivers, wildfires, and landslides, highlighting the compounding effects of climate change on these events. Caltrans is actively working to clear debris and maintain travel corridors in regions prone to landslides, like the Feather River Canyon.
As temperatures rise and the atmosphere holds more water vapor, the likelihood of intense storms and landslides in burn areas increases. Scientists are developing ways to predict the impact of atmospheric rivers and inform the public about potential hazards. Understanding the mechanics of these events and staying informed ahead of storms are crucial steps for communities to stay safe in areas prone to wildfires and landslides.
