A method for initiating movement of a mobile machine is provided. In response to determining that the mobile machine needs to move to a new location based on environmental parameters corresponding to a current position of the mobile machine, a safe location for the mobile machine is determined based on the environmental parameters. An estimated time of travel is calculated from the current position of the mobile machine to the safe location based on a selected travel route for the mobile machine. Then, movement of the mobile machine is initiated prior to a first estimated time when the selected travel route will be impassable due to the environmental parameters based on the estimated time of travel using the selected travel route from the current position of the mobile machine to the safe location.
