BayouWatch is an early-warning aid, not a substitute for official guidance from the National Weather Service, Harris County Flood Control District, or local emergency management. Always follow evacuation orders from official authorities.

Sensor readings, forecasts, and simulations shown on this site are provided on a best-effort basis and may be delayed, incomplete, or occasionally inaccurate due to hardware, network, or upstream data-provider issues.

BayouWatch is a nonprofit student research project built by Carnegie Vanguard High School students for the Houston community, and is provided as-is with no warranty of uninterrupted availability.
