Methods, systems, and computer-readable media provide for the reporting of an environmental condition to vehicles prior to encountering the environmental condition. According to various embodiments described herein, local environment data corresponding to the environmental condition is collected from sensors on a vehicle. The local environment data is used to determine that the environmental condition exists at the current location of the vehicle. A notification that includes the geographic location of the environmental condition is created and provided to one or more other vehicles in the vicinity of the environmental condition.
