Do you know whether your home is inside a red flag warning zone?
Vedant Thakker, who was 16 when a brush fire broke out in the hills above his Fremont neighborhood, built Red Flag Check, a free website and app. Users enter an address and see one of four location categories based on live National Weather Service data.
Why it matters
Red flag warnings often cover large geographic areas, leaving residents unsure whether their home is at risk. The tool aims to give Fremont residents a clearer picture of their personal exposure.
Red Flag Check classifies each address into one of four categories using live National Weather Service data. The source does not report usage numbers or accuracy testing for the tool.

The details

Seasonal Patterns
Red flag warnings are issued by the National Weather Service when hot, dry and windy conditions raise fire danger across broad areas. Red Flag Check narrows that regional signal to individual addresses in a way the official warning system does not.
Residents can check their address with Red Flag Check during red flag warnings, but the app is not a substitute for official alerts. Fremont residents should rely on AC Alert and Genasys Protect for evacuation orders.
The takeaway
A free address-level tool can help residents judge personal wildfire risk when broad warnings leave them uncertain. Official channels such as AC Alert and Genasys Protect should still guide any evacuation decision.
