The invention discloses an early warning method, device and system and a storage medium, which are used for improving the processing efficiency of an early warning service. The method comprises the steps that when it is detected that a traffic event of a preset type occurs at a target position, a target early warning service matched with the traffic event type is determined; according to the target early warning service, a target service group where the target position is located in a shared cache is judged, the shared cache is composed of a plurality of service groups, and each service group is used for storing part of map data in a preset area; accessing the target service group, and obtaining a network connection vehicle list in a preset range with a target position as a center from the target service group; and sending an early warning service to a network connection vehicle corresponding to the network connection vehicle list to inform the network connection vehicle corresponding to the network connection vehicle list that a preset type of traffic event occurs at the target position. By adopting the scheme, the resource utilization rate and the processing efficiency of the early warning service can be improved.
