Additionally, you may want to park your cars in garages instead of the street. They're calling for 115 mph winds and flying debris can do some damage. Also, it should go without saying, that flying debris can also injure or kill you... so while it may be tempting to go out and and run around in the storm, I'd recommend making your trips between your hotels and the convention center as quick as possible.
Hopefully the storm will just drift off course though.
