The invention is suitable for the technical field of road early warning, and provides a traffic accident early warning method and device, terminal equipment and a storage medium. The method comprisesthe steps of: acquiring the weather data of a target region in a target time period and the accident risk level of the target region; based on the weather data and the accident risk level, acquiring arisk assessment value of the target region in the target time period; acquiring vehicle position information, and predicting whether the vehicle passes through the target region in the target time period or not based on the position information; and if the vehicle passes through the target region in the target time period, sending an early warning signal to the vehicle, wherein the early warningsignal is generated based on a risk assessment value. According to the invention, whether the target region has a risk in the target time period is evaluated through the weather data and the accidentrisk level, risk evaluation is more accurate, in addition, the risk degree is sent to the vehicle, a driver can be reminded to drive safely, and accidents are avoided.
