My dad and stepmother are heading north away from Covington. They should be out of harms’ way by the time Katrina hits the city.

This is a list of sites which have information/visuals of the hurricane approaching the city:

New Orleans traffic cameras
List of live cameras and webcams
Causeway bridge camera

Satellite imagery of the hurricane
National Weather Service advisory for New Orleans
