VIDEO: A downside to the incredible amount of rain from the winter storms -- and beautiful green growth that came after -- is the increased quantity of fuels for wildfires.
Rising Bay Area temperatures are now drying out all the extra vegetation, putting many parts of California at higher wildfire risk.
2017 was a particularly bad year for the Wine Country wildfires. The smoke spreading across the Bay Area sparked an idea for a Campolindo High School senior to try to do something to help. "Everyone's lives were interrupted, lives were lost," said Vasya Tremsin, who co-founded Torch Sensors and is the company's COO. "Billions of dollars in damages, etc. So I thought to myself, 'Why is there a smoke alarm indoors that exists and is ubiquitous all around the world, but there is no outdoor smoke alarm for an outdoor fire sensor at all?'"
