1. An apparatus comprising at least one processor and at least one memory storing computer program code, the at least one memory and the computer program code configured to, with the processor, cause the apparatus to at least:

  • obtain road attribute data for a location, wherein the road attribute data indicates properties of a road segment at the location, wherein the road attribute data includes a weight associated with the road attribute data for the location;

    obtain real-time weather information for the location, wherein the real-time weather information for the location is associated with a weight based, at least in part, on a type of weather at the location;

    analyze the real-time weather information and the road attribute data based on a set of rules using the weight of the road attribute data for the location and a weight associated with the real-time weather information based on the type of weather at the location to determine whether a weighted combination of the real-time weather information and the road attribute data constitute a hazardous driving condition at the location;

    if the hazardous driving condition exists, generate a hazardous driving condition message comprising data identifying the location and data identifying the hazardous driving condition; and

    transmit over a communications network the hazardous driving condition message to a navigation device.
