When Wildfire Comes
Hello, my name is Dr. Christopher Potter and I am a wildfire scientist with over 30 years of experience working for NASA, and with local communities impacted by wildland fires. I have studied wildfire on the urban interface using satellite imagery and ground measurements for all of the most destructive fires in the western United States, and I myself live in a high-risk wildfire zone in northern California. In this weekly podcast, titled "When Wildfire Comes", we will hear from a special guest about their close encounter with a major wildfire that occurred during the past several years. This is not a breaking news report, but 30 minutes during which our guest recounts their emotions and their first-hand observations of a wildfire approaching and burning in their town or community, and the lessons to be learned from such a horrifying event.

In the later afternoon of Aug 8, 1997, I rushed home to Los Gatos, a small town in the Santa Cruz Mountains to the south of San Jose. A fire had broken out in the hills above town and that we were being asked to evacuate. I raced home to see helicopters overhead with water tankers attacking flames in the shrublands less than a mile from our home. The story continues in this inaugural episode of "When Wildfire Comes".
