This is a photo of I-37 heading north OUT of Corpus Christi, TX from Thursday afternoon; people are heeding the warnings to LEAVE before the storm arrives. Below are MANDATORY EVACUATION ORDERS issued by various governments.  

Understand that even though it is called "Mandatory" people are not forced to evacuate if they choose to remain on their property.  In such a situation, such persons are told that if they change their mind during the storm, and call for help to try to get out, NO HELP WILL BE SENT.  That's the price  free people pay when they ignore evacuations.
