First, no one knows where this storm is going, it's not even in the gulf yet, severe shift west... would put it in Texas, slight turn, west is more of what it's done.
The Eastern side has more rain and is considered the "bad" side of the storm. Depending on how big the storm is depends on what gets hit. Again this is a wait and see game.
Your husband will not be commuting after today. If the storm is close, everything will be shut down and contra flow will be put into effect at the earliest saturday. All roads lead out.
Keep an eye out, watch the storm and see what your particular parish recommends you do and then listen to them. Go to the red cross websites and other sites that tell you how to prepare for a storm. Let's put it this way, Katrina... we got the "good" side. Baton Rouge was out of power for a few days, to a week in some areas. Some of these storms are big.
The directions, mean the storm side, not the way it's moving. If it's the east side of the storm, it means east of the eye, no matter what direction it's moving in.
Hope this helps.
