For someone evacuating by bicycle, the main goal should be simply to get away from the storm surge, which for a Cat 5 storm in S. Louisiana, could be
30 MILES from the coast
I would ride north, find a public shelter in a steel framed building, and just try to survive it.
To ride straight west on I-10, you'd have to go a much longer distance to get away from the surge... and if the storm takes a sudden shift to the west, you and everyone sitting in gridlock traffic on I-10 is f***ed.
