Vedant Thakker was 16 years old when a brush fire in the hills above his Fremont neighborhood made wildfire risk feel personal. The California high school student later built Red Flag Check, a free website and app that lets people enter an address and see whether they are inside a National Weather Service red flag warning zone, downwind of one, adjacent to one, or outside the current warning area. He is now teaching seniors at Fremont’s Age Well Center how to use the tool, according to NBC Bay Area and the Oakland Firesafe Council.The project began with a simple frustration. Red flag warnings often cover large geographic areas, leaving residents unsure whether their own home is actually at risk. Vedant wanted a clearer answer, especially for older adults who may be more vulnerable during fast-moving wildfires.
A nearby fire changed his focus
Like many teenagers, Vedant had not paid much attention to the news before the brush fire broke out near his Fremont neighborhood. Seeing flames close to home changed that immediately. He recalled thinking that the fire was happening right there, near him, and that it felt unreal. From then on, he began paying closer attention to wildfires and to the red flag warnings issued when weather conditions raise the risk of fire.The problem, he found, was that those warnings did not always tell residents whether their particular address was affected. He wanted to know whether a home was directly at risk, and if so, how much. That question became the foundation for Red Flag Check.
What Red Flag Check does
Red Flag Check is available at redflag-check.info and uses live National Weather Service data. Users enter an address and receive one of four location categories: inside the warning zone, in a downwind threat area, adjacent to the warning zone, or outside the current warning area. That distinction matters because wildfire danger is not limited to the exact boundary of a warning. Vedant explained, as per the reports, that people who are not directly inside a warning area may still face a major indirect threat if they are downwind of a fire.The tool is free and is intended for informational use during red flag warning events. The Oakland Firesafe Council notes that it uses publicly available weather and fire data to help residents understand their relative position during dangerous conditions.
Built with AI, aimed at seniors
Vedant developed the app using publicly available weather and fire data, along with artificial intelligence to help him write the code. NBC Bay Area reported that he may have developed Red Flag Check largely on his own, but he did not create it for himself.For the past few years, Vedant has volunteered at the Fremont Age Well Center, where the seniors he works with have come to feel like family. As he researched wildfires, he learned how vulnerable older adults can be during disasters. He pointed to the 2018 Camp Fire, in which the average age of those who died was 72. That statistic helped make the seniors at the Age Well Center the natural first audience for his app.
Teaching seniors to use it
Vedant is now teaching the seniors how to use Red Flag Check, hoping that more specific information can give them greater confidence when wildfire conditions become dangerous. The app gives them a way to translate a broad regional warning into a more personal assessment of their location.The Oakland Firesafe Council praised the project for recognising a community need and for using volunteer time and programming skills to create a new resource. The organisation also shared the app with residents as part of its wildfire preparedness work.For Vedant, the response from seniors is what makes the effort worthwhile. He said he loves when they appreciate that he thought about them, adding that he feels it is something he should do given the affection they have shown him over the past two years.
A tool, not an evacuation alert
The Oakland Firesafe Council is clear that Red Flag Check is not a substitute for official emergency notifications. Residents are encouraged to rely on AC Alert, Genasys Protect and other official channels for evacuation orders and public safety information.The council also warns that people can still be at risk from a wind-driven wildfire even if they are outside a red flag warning area. It advises residents to stay informed, have a plan and be prepared.That framing is important. Vedant’s app does not replace emergency services or evacuation orders. Instead, it gives people a free, address-specific way to understand where they stand during a red flag warning and to take preparedness more seriously.
Why the project matters
Wildfire warnings often arrive as broad alerts covering cities, counties or entire regions. For someone unfamiliar with maps or weather terminology, it can be difficult to know whether a warning includes their street, their neighborhood or a nearby hillside.Red Flag Check tries to close that gap by turning live government data into four plain-language categories. The tool is especially useful for older adults, who may have less time to react in an emergency and may benefit from clearer, more local information.Vedant’s work shows how a student’s concern for his own neighborhood can become a practical community resource. A brush fire near his Fremont home led him to build a tool that now helps seniors understand wildfire risk, one address at a time.
