Because of their width, double-wide garage doors are more susceptible to wind damage than single doors. Unless you have a tested hurricane-resistant door, the wind may force it out of the roller track -- especially if the track is light weight or some of the anchor bolts are not in place. This occurs because the door deflects too much under excessive wind pressure and fails.
To secure your garage door:
If you decide to retrofit your garage door with a kit that allows you to operate the door after it is installed, make sure the door is balanced by lowering it about halfway and letting go. If the door goes up or down, the springs will need adjusting. Note: Since the springs are dangerous, only a professional should adjust them.
If you are unable to retrofit your garage door with a kit specifically designed for your door, you can purchase garage door retrofit kits to withstand hurricane winds at your local building supply store. Also, check to see if the supplier can do the installation.
